WHC-SD-W252.-ACDR-001, Rev. 0
Heating, Ventilating, and Air Conditioning The heating, ventilating, and air conditioning (HVAC) system will be designed to meet operating requirements during normal mode of operation. There will be a separate HVAC system for each side of the building. The HVAC systems will be designed for energy efficiency in accordance with the requirements of DOE Order 6430.1 A. The design parameters are as shown in the CDR. The ventilation for the pump room will be sized for the high heat load of the pumps.
Fabrication Shop Replacement Building The Kaiser Engineers Hanford Company (KEH) Fabrication Shop Replacement Building will not be needed because the fluid coolers will not be located where the shop is located. Therefore, the CDR references pertaining to this structure should be disregarded. Other Structures One 600-gallon fuel storage tank is specified in the CDR. The requirement for this tank has been deleted. Special Equipment and Processes Fluid Coolers (Replaces CDR Section on Cooling Tower) The fluid to be cooled will be circulated inside the tubes of the heat exchanger. The heat will flow from the process fluid through the coil tubes to the water outside which cascades downward over the tubes. Air is forced upward through the coil, evaporating a small percentage of the water. Sensible heat and the latent heat of vaporization are discharged to the atmosphere. The remaining water will fall to the sump to be recirculated by the spray pump while water entrained in the air stream will be reclaimed and returned to the sump by mist eliminators at the fluid cooler air discharge. The CDR references in the Cooling Tower section to the surface coil, spray water pump operations, and sensible cooling via forced air are not relevant to the fluid coolers. Pumps The closed-Joop cooling circulating pumps will be horizontal, single-stage pumps with mechanical seals, dynamically balanced impellers, and replaceable impeller and casing wear rings. The double-suction pumps will be of carbon steel construction. -91/26/95
Pumps will be powered by a National Electrical Manufacturer's Association (NEMA) electric motor designed for indoor operation. Air Cooler (Replaces CDR Section on Chillers) The process/instrument air compressors and after-cooler will be cooled using a separate closed-loop cooling water system. The primary heat sink for this system will be a small, dry surface air cooler designed to transfer heat from the cooling fluid to the air. The fluid to be cooled will be circulated inside the cooler tubes. Air will be forced upward through the cooler to dissipate heat to the atmosphere by sensible cooling. A backup raw water heat exchanger will be installed for use when the outdoor dry bulb temperature is too high to provide acceptable cooling water temperatures to the air compressors. Mechanical System Description Evaporator Condenser Closed Loop Cooling System The E-C-l, E-C-2, and E-C-3 condenser cooling water effluent will be eliminated by modifying the.existing once-through cooling system to a closed-loop cooling system. The proposed cooling water system will use a fluid cooler to remove waste heat from the evaporator condenser cooling water (see Engineering Sketch ES-252-ACD-10 through 14). Surge capacity will be provided by a surge/expansion tank. A separate chemical addition tank will be provided for addition of corrosion inhibitors to the closed-loop system. The design heat load of the cooling water system will be30xl0 Btu/hr.

Heating, Ventilating, and Air Conditioning The heating, ventilating, and air conditioning (HVAC) system will be designed to meet operating requirements during normal mode of operation. There will be a separate HVAC system for each side of the building. The HVAC systems will be designed for energy efficiency in accordance with the requirements of DOE Order 6430.1 A. The design parameters are as shown in the CDR. Fire Protection Fire protection criteria will be as described in the CDR. Electrical The discussion of electrical power in the CDR remains unchanged. 3. Special Equipment/Process Systems Wet Surface Fluid Coolers (Replaces CDR Cooling Section) Tower
The fluid to be cooled is circulated inside the tubes of the heat exchanger. Heat flows from the process fluid through the coil tubes to the water outside which is cascading downward over the tubes. Air is forced upward through the coil, evaporating a small percentage of the water. Sensible heat and the latent heat of vaporization are discharged to the atmosphere. The remaining water falls to the sump to be recirculated by the spray pump while water entrained in the air stream is reclaimed and returned to the sump by mist eliminators at the wet surface fluid coolers air discharge. Associated references in the CDR to the spray water pumps and heat dissipation by sensible cooling are not relevant to the fluid coolers. Pumps The closed-loop cooling circulating pumps, blowdown transfer pumps, and TEDF transfer pumps will be horizontal, single-stage pumps with mechanical seals, dynamically balanced impellers, and replaceable impeller and casing wear rings. The pumps will be of carbon steel construction. Pumps will be powered by a NEMA electric motor designed for indoor operation.
Heat Exchanger The exchanger will have a heat transfer surface area of 590 square feet with a removable tube bundle. The size of the heat exchanger is based on a conservative blowdown system heat load and flow rate. This load is currently being re-evaluated. The heat exchanger will be constructed with a carbon steel shell and stainless steel tubes. Mechanical System Description 284-E Powerhouse Cooling Water System Modification The list in the CDR of equipment connected to the closed-loop cooling system should include the following: Boiler blowdown heat exchanger. The heat sink for the 284-E Powerhouse closed-loop cooling system will be wet surface fluid coolers. The design heat load of the cooling water system will be 7.18 million Btu/hr. The proposed wet surface fluid coolers will be sized to permit operation at two cycles of concentration. At two cycles of concentration, the wet surface fluid cooler will produce a maximum blowdown flow of approximately 14.7 gpm. The maximum amount of spray water evaporated will also be approximately 14.7 gpm. A maximum of 29.4 gpm of makeup water will be required for wet surface fluid cooler operation. The only source of makeup water for the wet surface fluid coolers closed loop system will be the softened water system. Raw water will be used for the wet surface fluid cooler basins. The closed-loop cooling water will be circulated by a 25 hp horizontal pump. A redundant pump will be installed to provide operating and backup capability. The pumps will be operated alternately. Each pump is capable of delivering 400 gpm at 150 feet of total head. Both pumps will be electrically powered. Standby power will not be provided. The brine tank size will be the same as shown in CDR but will be located southeast instead of east of the powerhouse. The softener regenerate will be discharged to the TEDF by a 1-1/2 hp horizontal pump. A redundant pump will be installed to provide -251/26/95

Electrical System Description No changes from the CDR are required for the ACD except that references to the cooling towers should be replaced by wet surface fluid coolers. PTECS Description The TEDF transfer pump(s) and fluid cooler overflow pump(s) (if required) will transfer the effluent through a new 2-inch drain line to a new manhole. The flow from the 282-E and 283-E will also discharge into this manhole. From this manhole, a new 6-inch PVC line will carry the effluent to the TEDF. The waste stream will pass through a sampling and monitoring station and a metering manhole enroute to the TEDF. The routing of the TEDF will be essentially the same as the existing 42-inch concrete pipe (see Engineering Sketch ES-252-ACD-29). The new drain piping will be installed underground for freeze protection. The new 6-inch line will be graded for gravity flow. Consideration was given to using the existing 42-inch concrete pipe as a PTECS line. In order to accommodate the design flow of 33 gpm (FDC Appendix A, Table A-l) at a self-cleaning velocity of 2 feet per second, with an estimated Manning roughness coefficient of 0.013 for concrete pipe, over the distance of about 3600 feet from the powerhouse to the proposed TEDF transfer line junction with an estimated slope of 0.0062, a full-flowing pipe of 3-inch diameter would be required. A larger concrete pipe would have a velocity less than 2 feet per second. Thus, the 42-inch concrete pipe would be too large to maintain a self-cleaning velocity of flow. A more direct re-routing of the PTECS line to connect with the TEDF transfer line directly north of the facility will be considered during Definitive Design, after KEH develops the data necessary to evaluate this option. Telecommunication System Description No changes are needed to the CDR for the ACD.
Demolition No changes are needed to the CDR for the ACD.
282-E Raw Water Reservoir Reservoir Level Control. The level in the 282-E Raw Water Reservoir will be controlled in order to minimize overflows from the reservoir (see Engineering Sketch ES-252-ACD-37). The level will be controlled in a manner identical to the level control in the 282-W Raw Water Reservoir. An ultrasonic level transducer will measure the reservoir level and transmit the level to a level controller. This controller will control an inlet control valve which will modulate the flow into the reservoir in order to maintain a constant level in the reservoir. At the 282-E Raw Water Reservoir there are two inlet houses, the 282-EA and the 282-EB Weir Houses. Presently the inlet pipes to these two inlets are not interconnected near the reservoir, however, an intertie will be installed immediately adjacent to the reservoir. There is an existing 8-inch bypass pipe located immediately adjacent to the 282-EA Weir House which will also be connected to the intertie between the two weir houses. The inlet control valve will be installed on this bypass pipe. The inlet control valve will consist of an 8-inch motor-operated V-port ball valve. Hows in the range of 0 to 3,000 gpm will flow through this pipe. A manual 8-inch gate on the bypass pipe upstream of the V-port ball valve will be manually adjusted to reduce the pressure on the inlet flow to approximately 55 psig. The remaining pressure drop will occur across the motor-operated V-port ball valve to control the flow. Flows greater than 3,000 gpm will flow through an orifice plate installed in the position of the existing 12-inch cone valve in the 282-EB Weir House. This orifice plate will pass up to 2,000 gpm. (Therefore, maximum flow into the reservoir would be 5,000 gpm). If it is necessary to provide flows greater than 3,000 gpm, an operator would have to open a manual gate valve to allow the flow to pass through this pipe (the remainder of the flow would come through the 8-inch bypass pipe and V-port ball valve). If the reservoir water level becomes too high when the pipeline in the 282-EB Weir House with the orifice plate is operating, a high level switch will automatically close a knife gate valve installed on this line. Then the flow would come entirely through the 8-inch bypass pipe. The piping inside the 282-EA Weir House will be abandoned in place. Drainage Modifications. Other modifications will be similar to the 282-W Reservoir. A new pipe will be installed in the 282-E Reservoir overflow to carry any overflow to the new PTECS pipeline. Also a sump pump will be installed in the 282-E Reservoir Pump House to pump floor drainage in the pump house to the new PTECS pipeline.

WHC-SD-W252-ACDR-001, Rev. 0 3.2.8 Heat Tracing Heat tracing involves placement of heating elements under the insulation of piping and equipment. Electric or steam heat tracing may be used. This will find application on sections of above ground pipe and equipment which are undrainable or otherwise unprotected during periods of low heat load. 3.2.9 Supplementary Heating WSFCs can have electric heaters installed in the sumps to prevent the water temperature from dropping below a preset value. This is very frequently done. 3.2.10 Protection of Auxiliary Components In general, three different ways of auxiliary component freeze protection may be provided: heat tracing; housing in a new heated building; and, housing in an existing heated building. The protection methods for these components depends on the component to be protected and its physical location and location relative to other components. In general, a single piece of equipment installed outside could be protected by insulation and heat tracing. However a small building would be more appropriate to protect several components that need to be located in the same area. If equipment can be located in an existing, heated building no additional protection would be required. Each situation is individually evaluated to determine the most appropriate method. In terms of priority, use of a small pre-engineered heated buildings appears to offer the best solution because it would optimize layout and maintenance access. Existing heated buildings will receive second consideration due to the complexity of locating new equipment in an existing facility. Space must be found, evaluated and discussed with the building staff to determine acceptability. Where appropriate, valving should be leak tight to prevent leakage of water into a section of piping where freezing could occur. Valve materials, especially seat materials, must be carefully selected to be reliable in cold weather. In addition, drains are required to eliminate any leakage into the dry piping. 3.3 WSFC Location and Orientation Considerations The WSFC should be located away from structures which would present a restriction or any other interference to inlet and outlet airflow of the WSFC. The A-6

WHC-SD-W252-ACDR-001, Rev. 0 valves will be removed and reinstalled as part of W-252. These valves must be shown on subsequent design drawings. Existing control valve FV-ECl-1 is installed in the 12-inch raw water discharge piping from the primary condenser. Control valve FV-EC3-1 is installed in the 3-inch raw water discharge piping from the after condenser. The conceptual P&IDs show FV-EC3-1, along with the associated bypass piping and instrumentation, as being used. Control valve FV-ECl-1 will be reused, with the required instrumentation and bypass piping, in the primary condenser 12-inch discharge piping. Because closing these control valves could isolate the entire flow from circulation pumps P-J-101 and P-J-102, a minimum flow recirculation line will be installed from the discharge header to the suction header of the pumps. The piping and control valve will be sized for approximately 25 percent design flow from one circulation pump. The minimum flow control valve will automatically open as required to protect the pumps during low flow conditions. SOW 10.2.3.2d and Open Item 21: Evaluate the use of a fan coil unit to supply closed-loop cooling to the compressor jackets instead of a chiller. The cooling water requirements for the compressors, CP-E-1 and CP-E-2, as well as the aftercooler have been evaluated. The maximum allowable cooling water temperature for the compressors is 115 F, based on manufacture's information. A maximum cooling water temperature of 115 F is also acceptable for the aftercooler. An analysis has been performed to size a dry fan coil unit for this application. Based on this evaluation, a dry fan cooler is appropriate for this application and will be included in the design. However, in the event of extremely high ambient temperatures, additional cooling will be required to maintain the maximum cooling water temperature. A supplemental water-towater cooler will be included in the design to ensure the cooling water does not exceed 115 F. Open Item 23: The water chemistry control for the closed-loop and the cooling towers requires evaluation to determine (1) control and equipment required and (2) if a FDC change is required. As discussed in response to open item 5, design changes to control the closedloop system chemistry are recommended. Concentrated corrosion inhibitor could be added to the system by manually filling chemical addition tanks. The system chemistry would be monitored by analyzing water samples taken from a local sample connection. A manual chemical addition system is appropriate for a closed-loop system of this type because the water chemistry should only require infrequent adjustment. The same system would be used to control chemistry with the system operating or shut down. However, it would be necessary to operate a circulation pump while adding chemicals during shut down periods. B-4

WHC-SD-W252-ACDR-001, Rev. 0 small increases in contamination with the same degree of accuracy as the PIOPS or other equivalent commercially available instruments. Recommendation: Retain this system in its current configuration. A new "Best Available Technology" (BAT) radiation monitor is slated to be installed down stream of this location. Open Item #13, "Need to provide additional guidance for on-line alpha-beta monitoring which is compatible with commercially available instruments.": The drawing ES-252-Y8 in the Conceptual Design Report entitled, "P & ID, 241-A EFL Monitoring System," for the proposed liquid effluent radiation monitoring systems for 244AR and 241-A shows independent sample stream pumps for the alpha-beta monitoring instruments. The PIOPS that have been previously manufactured for WHC have been designed with pumps as a part of the system. This reports recommends the use of PIOPS liquid effluent monitors for the W-252 Project, however the preferred procurement will not come with the monitoring skids equipped with a sample pump. The FDC contains a statement which calls for continuous alpha-beta monitoring. Continuous alpha monitoring of a liquid effluent is not possible. Alpha analysis of liquids must be performed by liquid scintillation or solid-state spectrographic technologies in laboratories. Recommendation: The above referenced drawing should be changed to show radiation monitoring skids without independent sample pumps. Also, amend the-FDC to indicate continuous beta-gamma monitoring. EVALUATION Regulatory Requirements: Releases to the soil column are defined to include effluent discharge to surface ponds. Currently the combined B-Plant cooling water effluent and chemical sewer effluent join into a single line that is discharged to B-Pond under normal operating conditions. Project W-049 intends to reroute the B-Plant chemical sewer into the 200 Area Treated Effluent Disposal Facility (TEDF). Project W-252 plans to reroute the B-Plant/WESF cooling water line and the 242A Evaporator steam condensate line into TEDF. Regulatory requirements state that the dose shall be limited to 0.04 mSv/yr (4 mrem) from discharges to the soil column. This limit is based on unlimited continuous public use (i.e. 2 liter/d consumption from public drinking water supplies). Derived Concentration Guides (DCG) for liquid effluent are established by the Department of Energy (DOE Order
WHC-SD-W252-ACDR-001, Rev. 0 5400.5). This DOE Order provides the concentrations of radionuclides in water for continuous unrestricted use from exposure to water for one year resulting in an effective dose equivalent of 1.0 mSv (100 mrem). Four percent of the DCG provides the basis for establishing public drinking water radionuclide limits. The following concentrations (0.04 x DCG) are the individual maximum average radionuclide concentrations acceptable to maintain regulatory compliance for the radionuclides of interest in the present systems evaluated [A note to the reader, a sum of concentrations rule must be applied to calculate the 0.04 mSv dose (4 mrem); this requires calculating the percentages of maximum concentrations of the individual radionuclides and summing the percentages ( DOE Orders 5400.1 and 5400.5, and WHC-CM-7-5)].
