SUMMARY

DESCRIPTION purpose of the irradiation facility (IF) cooling systems is to safely remove the fission and ay heat from the target solution and dissipate it to the environment. The primary closed loop ling system (PCLS) removes heat from the subcritical assembly. The light water pool vides passive heat removal for the subcritical assembly and is described in detail in tion 4a2.4. The radioisotope process facility cooling system (RPCS) is the secondary cooling tem for the facility. See Chapter 13 for a discussion of accident scenarios.

target solution vessel (TSV) and neutron multiplier within each IU are cooled by the PCLS e the IU is in operation. The PCLS is a closed loop chilled water system that rejects heat to RPCS, an intermediate chilled water loop, which rejects heat to the process chilled water tem (PCHS). The PCHS is a closed chilled loop that rejects heat to the atmosphere by use of cooled chillers. Figure 5a2.1-1 depicts the heat flow path from generation to the environment.

neutron driver cooling is addressed in Section 4a2.3 and the recirculating heating, tilation, and air conditioning (HVAC) fan-coil unit that is part of the radiological ventilation e 1 recirculating cooling subsystem (RVZ1r) is discussed in Section 9a2.1.

primary and secondary IF cooling systems maintain the capability to provide sufficient heat oval to support continuous operation at full licensed power as discussed in the subsequent tions.

.2.1 DESIGN BASES AND FUNCTIONAL REQUIREMENTS primary closed loop cooling system (PCLS) provides forced convection water cooling to the et solution vessel (TSV) and neutron multiplier during irradiation of the target solution and ediately prior to transferring target solution from the TSV to the TSV dump tank. The PCLS provides indirect cooling of the light water pool via natural convection heat transfer to the LS components submerged in the pool, as described in Subsection 4a2.7.3. The PCLS cts heat to the radioisotope process facility cooling system (RPCS). A total of eight pendent instances of PCLS are installed in the SHINE facility, one for each irradiation unit

. There are no common pressure retaining components between the instances of PCLS. The or PCLS equipment is located in the primary cooling room and the IU cell.

h instance of PCLS includes two pumps, a heat exchanger, and a cooling water clean-up stream located in the primary cooling rooms adjacent to the east side of each IU cell. In the ell, the PCLS is connected to the subcritical assembly system (SCAS) and includes an air arator, an expansion tank, and nitrogen-16 (N-16) delay tanks. Figure 5a2.2-1 provides a LS flow diagram.

process functions of the PCLS cooling system are to:

• remove heat from each TSV and neutron multiplier during full-power IU operation;

• cool the light water pool by natural convection heat transfer to PCLS components inside the light water pool;

• maintain water quality to reduce corrosion and scaling;

• limit concentrations of particulate and dissolved contaminants that could be made radioactive by neutron irradiation;

• reduce N-16 radiation exposure within the primary cooling room in support of as low as reasonably achievable (ALARA) goals; and

• remove entrained gases from the cooling water.

LS removes heat from the TSV and neutron multiplier during startup and irradiation by ulating water in an upward direction [

]PROP/ECI along the exterior surfaces of the TSV and neutron multiplier walls. The subcritical embly support structure (SASS) provides the shell side pressure boundary to direct the ling water flow past the TSV and neutron multiplier. The PCLS is attached to the SASS upper lower plenums.

LS is designed to remove a minimum of 580,000 British thermal units per hour (Btu/hr) 0 kilowatts [kW]) of heat from each IU during full-power operation and during shutdown ditions when target solution is in the TSV.

LS is designed to maintain the pressure of the cooling water in the SASS higher than the rnal pressure of the TSV. The TSV is designed and fabricated to prevent target solution from ing into the PCLS. See Section 4a2.4 for additional information related to the TSV.

PCLS cleanup side stream maintains system cooling water quality. The PCLS is designed to rate without corrosion inhibiting chemicals in the process fluid. The cleanup side stream can NE Medical Technologies 5a2.2-1 Rev. 0

PCLS piping confines the cooling water within the IU cell and within the primary cooling room ted adjacent to the IU cell. Pressure retaining components are constructed of materials that ctively resist corrosion to limit activation products that could cause increased radiation osure of personnel and surrounding equipment. Major components are constructed of tenitic stainless steel.

PCLS air separator separates entrained gases from the cooling water and directs the gases he radiological ventilation zone 1 exhaust (RVZ1e) subsystem via the PCLS expansion tank.

6 is generated in the cooling water by the neutron activation of oxygen. Section 5a2.7 vides a discussion of the treatment of N-16 in the cooling water.

rpressure protection for PCLS is provided by system design. The shutoff head of the PCLS ps is below the PCLS design pressure. The PCLS is also directly vented to RVZ1e through PCLS expansion tank.

Table 5a2.2-1 for the PCLS operating parameters. See Table 5a2.2-2 for a list of the PCLS ponents.

.2.2 PCLS ANALYSES ailed analysis of the PCLS target solution cooling performance is found in Section 4a2.7.

t transfer and temperature profiles for the neutron multiplier are found in Subsection 4a2.2.6.

tive cooling to the TSV and neutron multiplier is unavailable, irradiation of the target solution be suspended. Target solution in the TSV will be transferred from the TSV to the TSV dump

, which is passively cooled by the light water pool. See Subsection 4a2.4.2.2 for the heat oval capacity of the light water pool. Loss of cooling design basis accidents are discussed in section 13a2.1.3.

PCLS pumps operate in parallel to provide the design flowrate to the PCLS heat exchanger.

uld one pump fail, the second pump, operating at a minimum of [

]PROP/ECI, provides adequate cooling to allow continuation of full-power irradiation while ntaining the bulk target solution temperature less than 176°F (80°C) within the TSV.

light water pool and TSV are located within the primary confinement, which also provides finement of the components of the PCLS located within the IU cell, as discussed in tion 6a2.2. The PCLS piping penetrations through primary confinement are located above minimum acceptable water level in the pool.

elding to protect workers and reduce dose rates to equipment is provided by the irradiation biological shield (ICBS), described in detail in Section 4a2.5.

cts resulting from a primary cooling water breach are discussed in Subsection 4a2.7.3.7.

s of primary cooling water does not result in loss of integrity of the primary system boundary B). Low cooling water flow causes an IU Cell Safety Actuation, which results in the TSV dump es opening and the target solution draining to the TSV dump tank. The thermal mass of the NE Medical Technologies 5a2.2-2 Rev. 0

atural convection heat transfer. See Subsection 4a2.7.3.8 for further discussion on the sition from forced to natural convection.

ding of the SCAS cooling channels caused by loss of primary cooling water causes reactivity rtions as discussed in Subsection 13a2.1.2. To prevent the drainage of primary cooling water the SCAS, the SCAS is located below grade in the light water pool. Portions of the PCLS ted outside of the light water pool are above grade to prevent gravity drainage of the SCAS ling channels.

PCLS pumps draw cooling water from a line connected to the PCLS expansion tank.

ause the expansion tank is vented, a leak of the PCLS pressure boundary would result in the LS expansion tank level reducing until the PCLS return line breaks vacuum. Once the PCLS rn line breaks vacuum, the PCLS pumps cannot draw more water out of the SCAS. This ngement ensures that the PCLS pumps cannot draw the water out of the SCAS cooling nnels.

use of centrifugal pumps and an air separator prevents the PCLS from effectively voiding the ling channels by pumping air into the SCAS.

functions or leaks in the PCLS do not cause uncontrolled release of primary cooling water ide the radiologically controlled area (RCA). The facility structure (FSTR) provides barriers at s from the RCA to prevent the release of potentially contaminated water to the uncontrolled ironment.

PCLS piping penetrating confinement boundaries are provided with isolation capabilities.

ng systems that pass between confinement boundaries are equipped with either:

• a locked closed manual isolation valve, or

• an automatic isolation valve that takes the position that provides greater safety upon loss of actuating power.

nual isolation valves are maintained locked-shut for any conditions requiring confinement ndary integrity. The automatic isolation valves are closed as part of an IU Cell Safety uation if the TSV reactivity protection system (TRPS) detects a malfunction of PCLS, akage of primary cooling water into the PSB, or outleakage of target solution into the primary ling water.

.2.3 INSTRUMENTATION AND CONTROL ssure, flow, temperature, conductivity, and level instrumentation monitor the operating ameters of the PCLS.

perature instrumentation is provided to ensure the cooling water supply temperature ains within allowable limits despite variations in TSV power. Output from the temperature rumentation is used for controlling the flow of RPCS water through the PCLS heat exchanger egulate the cooling water supply temperature at the SCAS cooling water inlet.

rate with either one or both pumps operating.

e PCLS temperature or flowrate is outside allowable limits, the TRPS initiates an IU Cell ety Actuation, resulting in a transfer of the target solution to the TSV dump tank where it is led by natural convection to the light water pool.

ansion tank level instrumentation provides indication of loss of cooling water, such as by poration or radiolysis. Addition of makeup cooling water is a manual operation. Expansion level instrumentation can also perform a leak detection function as described in section 5a2.2.6.

ductivity instrumentation is provided to measure the conductivity of the PCLS water and nitor the performance of the PCLS cleanup side stream. Conductivity instrumentation can also orm a leak detection function as described in Subsection 5a2.2.6.

PCLS pressure, flow, temperature, and expansion tank level indications are available locally in the control room. Sampling and analysis of cooling water from the PCLS is performed lly. System operational controls are in the control room.

.2.4 RADIATION MONITORS AND SAMPLING RVZ1e line ventilating the PCLS expansion tank headspace is equipped with radiation nitors. The RVZ1e radiation monitors are intended to detect leakage of target solution or on product gases from the PSB or neutron multipliers. If radiation exceeding a predetermined oint is detected, the TRPS initiates an IU Cell Safety Actuation and the RVZ1e line is ated.

mpling and analysis of the water from the PCLS is performed to ensure that the water quality uirements are being maintained and contaminants are not present in the cooling water.

ntaining water quality ensures functional and safe operation by reducing corrosion damage scaling. See Table 5a2.2-1 for water quality requirements. Sampling of cooling water for ological contaminants is performed to detect possible leakage of target solution into the PSB.

.2.5 PCLS INTERFACES system interfaces of the PCLS are listed in Table 5a2.2-3.

PCLS cooling water is pumped through the PCLS heat exchanger, where the heat is sferred to the RPCS and subsequently transferred to the process chilled water system HS), where it is dissipated to the environment.

PCLS cooling water leaves the SCAS and enters the PCLS air separator, which allows ained radiolytic gas to separate from the cooling water. Besides hydrogen and oxygen, the dspace contains air, water vapor, and small amounts of N-16 and argon-41 (Ar-41). An rface between the RVZ1e and the expansion tank allows radiolytic gases to be purged to Z1e, preventing the buildup of hydrogen gas. Ambient air from within the primary confinement ndary is drawn through a flame arrestor and filter for sweeping of the expansion tank dspace.

NE Medical Technologies 5a2.2-4 Rev. 0

rface with the FDWS. This prevents possibly contaminated PCLS cooling water from coming ontact with the makeup water. The backflow prevention components help ensure the ALARA elines in Chapter 11 are met.

.2.6 LEAK DETECTION k detection is provided by the PCLS expansion tank level instrumentation, TSV dump tank l instrumentation, and conductivity instrumentation. Leak detection is also provided by ation monitoring and sampling, as discussed in Subsection 5a2.2.4.

expansion tank includes level instruments that allows operators to trend levels within the LS, which can indicate slow leaks of cooling water. Additionally, level indication in the TSV p tank provides indication of inleakage of cooling water into the PSB. If inleakage into the B is detected, the TRPS initiates an IU Cell Safety Actuation.

ductivity instrumentation can detect increases in conductivity of the PCLS cooling water ulting from inleakage of target solution.

.2.7 HYDROGEN LIMITS iolysis of the primary cooling water and the light water pool water results in the generation of rogen and oxygen gases. These gases must be vented to prevent the buildup of hydrogen.

RVZ1e draws air from the primary confinement and through the PCLS expansion tank dspace to dilute hydrogen within the primary confinement and expansion tank while the LS system is required to be in operation.

ing full-power irradiation, up to approximately 0.15 standard cubic feet per hour (scfh) standard cubic centimeters per minute [sccm]) of hydrogen gas is calculated to be generated e primary cooling water and up to approximately 0.38 scfh (180 sccm) of hydrogen is ulated to be generated in the light water pool.

Z1e provides a nominal flowrate of approximately 1 standard cubic feet per minute (scfm) standard liter per minute [slpm]) to the expansion tank headspace while the PCLS system is uired to be in operation. The relatively low nominal flowrate maintains hydrogen centrations within the primary confinement and expansion tank below 1 percent by volume e minimizing release of Ar-41 to the facility stack. Rates of Ar-41 production and release are cribed in Section 11.1.

.2.8 TECHNICAL SPECIFICATIONS tain material in this section provides information that is used in the technical specifications.

.3.1 DESIGN BASES AND FUNCTIONAL REQUIREMENTS radioisotope process facility cooling system (RPCS) removes heat generated from within the ological control area (RCA) and rejects the heat to the process chilled water system (PCHS).

RPCS is an intermediate closed-loop forced liquid cooling system that recirculates cooling er. The RPCS removes heat from the primary closed loop cooling system (PCLS), the tron driver assembly system (NDAS) cooling cabinets, the target solution vessel off-gas tem (TOGS), the recirculating heating, ventilation, and air conditioning (HVAC) fan-coil units are part of the radiological ventilation zone 1 recirculating cooling system (RVZ1r), the rculating HVAC fan-coil units that are part of the radiological ventilation zone 2 recirculating ling system (RVZ2r), the target solution preparation system (TSPS), the process vessel vent tem (PVVS), and the molybdenum extraction and purification system (MEPS). The total and placed on the RPCS by other systems is approximately 11.6 million British thermal units hour (MMBtu/hr) (3400 kilowatts [kW]). The RPCS consists of a heat exchanger, pumps, tem expansion tank, valves, instrumentation, and heat exchanger interfaces identified above.

RPCS major equipment is located in the RPCS room, within the RCA.

process functions of the RPCS are to:

• maintain higher pressure than the cooling systems served at the respective interfaces;

• remove process heat from systems served;

• maintain cooling water quality to reduce corrosion and scaling; and

• reject heat to the PCHS.

RPCS is a nonsafety-related system and is not credited with preventing or mitigating any ign basis events. See Figure 5a2.3-1 for the process flow diagram of the RPCS. See le 5a2.3-1 for the RPCS design and operating parameters. See Table 5a2.3-2 for the RPCS ponents.

.3.2 RPCS ANALYSES cooling function of the RPCS is not credited in the safety analysis for any system served by RPCS. If active cooling to the TSV and neutron multiplier is unavailable due to a loss of the CS, irradiation of the target solution will be suspended. Any target solution in the TSV will be sferred from the TSV to the TVS dump tank which is passively cooled by the light water pool.

tion 4a2.4 provides a discussion of the heat removal capacity of the light water pool. Loss of ling design basis accidents are discussed in Subsection 13a2.1.3.

essure cascade is maintained at each system heat exchanger that receives service such that RPCS cooling water is maintained at a higher pressure than those systems with the potential ontaminate the RPCS. Additionally, the PCHS is maintained at a higher pressure than the CS at the RPCS heat exchanger so that any leakage between the RPCS and the PCHS will d to leak into the RPCS.

keup water to the RPCS is from the facility demineralized water system (FDWS) as described ection 5a2.6. The RPCS piping includes backflow prevention components at the interface the FDWS. This prevents potentially contaminated RPCS cooling water from contacting the NE Medical Technologies 5a2.3-1 Rev. 0

.3.3 INSTRUMENTATION AND CONTROL process integrated control system (PICS) monitors the RPCS pressure, flow, temperature, conductivity to ensure operation within design parameters. Instrumentation is located in the CS loop to obtain accurate system operating information. Setpoints ensure that operators are ted when operating conditions are out of specification. Pressure, flow, and temperature are nitored within the RPCS to ensure that the system is operating within design conditions. Flow trol is provided on the downstream side of each interfacing systems heat exchanger.

onductivity analyzer is located near the RPCS heat exchanger and pump to monitor the ductivity of the RPCS cooling water. If the conductivity measurement is out of system rable parameters, operators are alerted such that the appropriate corrective actions can be

n. This protection limits corrosion and scaling damage in the RPCS system. Pressure, flow, temperature instrumentation on the supply and return lines of the RPCS can indicate a function in the system with an increase in pressure drop and/or low system flow. See le 5a2.3-1 for the RPCS operating parameters.

heat removal provided by RPCS to the PCLS is controlled by adjusting the RPCS flow rate ach heat exchanger. The RPCS flow rate is controlled on the return side of the process tem heat exchanger by means of a modulating flow control valve. This arrangement ensures the pressure differential between the RPCS and the PCLS is maintained, regardless of the ition of the temperature control valves.

.3.4 RADIATION MONITORS AND SAMPLING design of the cooling system ensures that release of radioactivity through the secondary ling system to the unrestricted environment will not lead to potential exposures to the public in ess of the requirements of 10 CFR 20 and the ALARA program guidelines. The RPCS is ntained at a higher pressure than the systems served. Furthermore, the RPCS is a closed system located inside the RCA. The facility structure (FSTR) provides barriers at exits from RCA to prevent the release of potentially contaminated cooling water to the uncontrolled ironment.

mpling and analysis of cooling water from the RPCS is performed to ensure radiological taminants are below acceptable limits. If unacceptable levels of contamination are found, the tem will be shut down and the contaminated cooling water will be purified using ion exchange

s. Operators then inspect the malfunctioning equipment and remedy the issue accordingly.

mpling and analysis of the cooling water from the RPCS is also performed to ensure that the er quality requirements are being maintained. Maintaining cooling water quality minimizes the ential for damage due to corrosion and scaling. Table 5a2.3-1 describes the RPCS cooling er quality requirements.

.4.1 DESIGN BASIS AND FUNCTIONAL REQUIREMENTS process chilled water system (PCHS) removes heat from the radioisotope process facility ling system (RPCS) from within the radiologically controlled area (RCA) and rejects the heat he environment. The PCHS interfaces with the RPCS heat exchanger and is comprised of ulation pumps, flow control valves, an expansion tank, a buffer tank, a glycol makeup unit, rumentation, and packaged air-cooled chillers. The PCHS is a forced liquid, convective flow, ed loop cooling system that uses air-cooled chillers to facilitate heat rejection to the ironment. The PCHS is designed to remove the total heat transfer demand placed on RPCS ther systems.

PCHS is a nonsafety-related system and is not credited with preventing or mitigating any ign basis events. Table 5a2.4-1 provides the PCHS operating parameters. Table 5a2.4-2 vides a description of PCHS components. Figure 5a2.4-1 provides a process flow diagram of PCHS.

process functions of the PCHS are to:

• remove heat from the RPCS heat exchangers;

• reject heat to the environment;

• maintain water quality to reduce corrosion and scaling; and

• prevent freezing of exterior piping and components.

PCHS is designed for local outdoor operation. The system is operated with a propylene ol/water mixture through the RPCS heat exchanger. Process generated heat is transferred the facility process systems into the RPCS inside the RCA. The RPCS transfers this cess heat to the PCHS through the RPCS heat exchanger, located inside the RCA. The HS then routes the process heat outside the RCA, and ultimately out of the facility to air-led chillers. The PCHS is provided makeup water from the facility demineralized water tem (FDWS), which is described in Section 5a2.6, and glycol through a manual fill point for mal operation. Table 5a2.4-1 describes the PCHS water quality requirements.

.4.2 PROCESS CHILLED WATER SYSTEM ANALYSES PCHS is designed to remove the total heat transfer demand placed on the RPCS by other tems of approximately 11.6 MMBtu/hr (3400 kW). The PCHS is maintained at a higher ssure than the RPCS to ensure that leakage at the system interface heat exchanger flows potentially less contaminated cooling water to potentially more contaminated cooling water.

.4.3 INSTRUMENTATION AND CONTROL PCHS provides output signals to the process integrated control system (PICS) for the nitoring of cooling water temperatures, pressures, tank level, and flow rates.

ssure, flow, tank level, and temperature measurement instrumentation are strategically ted in the PCHS cooling loop to obtain system operating information. Setpoints ensure that rators are alerted when an operating condition is out of specification. Buffer tank level oints are monitored to indicate high or low system volume conditions.

RPCS, transfers heat from the PCLS to the PCHS. The PCHS dissipates the heat from the CS to the environment. The RPCS is maintained at a lower pressure than PCHS at the RPCS t exchanger as such any leakage between RPCS and PCHS would tend to leak into RPCS.

PCLS, RPCS, and PCHS are closed loop systems. Samples of cooling water are analyzed contamination and conductivity. The contaminated volume of cooling water is recycled in er an on-site recycling unit or a mobile service unit. Water quality is maintained to reduce osion and scaling in the system. System cooling water level is monitored to provide indication ystem in-leakage or out-leakage. These design features ensure that radioactivity is not ased through the PCHS to the unrestricted environment and will not lead to potential osures of the public in excess of the requirements of 10 CFR 20 and the as low as reasonably ievable (ALARA) program guidelines.

system interfaces of the PCHS are listed in Table 5a2.4-3.

.5.1 DESIGN BASES AND PROCESS FUNCTIONS primary closed loop cooling system (PCLS) cleanup side stream maintains the required er quality limits of the PCLS.

following are the process functions of the PCLS cleanup side stream:

• Maintain water quality to reduce corrosion and scaling; and

• Limit concentrations of particulate and dissolved contaminants that could be made radioactive by neutron irradiation to achieve as low as reasonably achievable (ALARA) goals.

PCLS cooling water is treated to meet water quality limits discussed in Table 5a2.2-1. The nup components are located on a side stream through which the PCLS diverts a portion of cooling water flow. The components that perform the PCLS cooling water treatment are ted within the PCLS cleanup side stream flow path.

PCLS cleanup side stream includes conductivity instrumentation to monitor water quality, nizer beds to remove ionic species, and filters on the inlet and outlet of the deionizer beds to ove particulates from the cooling water.

ntaining the design water quality limits corrosion damage and scaling of the PCLS, the target tion vessel (TSV), and the neutron multiplier, which are components of the subcritical embly system (SCAS). The PCLS cleanup side stream removes contaminates that could ome activated and radioactive materials from the PCLS cooling water in order to meet RA occupational exposure goals described in Section 11.1. The PCLS cleanup side stream its components are designed and selected so that malfunctions are unlikely. Malfunctions leaks in the PCLS and the PCLS cleanup side streams are addressed in Subsection 5a2.2.2.

PCLS cleanup side stream components are designed and fabricated in accordance with the es and standards listed in Table 5a2.2-2.

.5.2 PCLS CLEANUP SIDE STREAM CONTROL AND INSTRUMENTATION PCLS cleanup side stream instrumentation is located in the primary cooling room.

ductivity instrumentation located at the outlet of the PCLS cleanup side stream measures the ductivity within the PCLS. The pH of the PCLS cooling water is monitored through sampling he system and analysis of the cooling water is performed by the quality control and analytical ing laboratories (LABS). Pressure, flow, temperature, conductivity, and level instrumentation nitor the operating parameters of the PCLS as discussed in Subsection 5a2.2.3.

.5.3 PCLS CLEANUP SIDE STREAM COMPONENTS AND LOCATIONS PCLS cleanup side stream components are located in the primary cooling room, directly cent to the IU cells.

nup side stream. After the PCLS cooling water is diverted to the PCLS cleanup side stream, st flows through a pre-filter, through a deionizer bed and finally through a post-filter. Following process, the PCLS cooling water side stream is reintroduced into the PCLS main flow path r to entering the SCAS.

.5.4 MAINTENANCE AND TESTING PCLS cleanup side stream pre-filters, post-filters, and deionizer units are replaced at regular rvals in accordance with maintenance procedures. Spent filters and deionizer units are osed of as radioactive waste via the solid radioactive waste processing (SRWP) system.

her discussion of SRWP can be found in Section 9b.7. Subsection 11.2.2 addresses pliance with 10 CFR 20 and presents ALARA guidelines relative to radioactive waste control.

le 11.2-1 provides a list of solid radioactive wastes including an estimate of annual quantities erated and disposal destinations.

mpling and testing of the PCLS cooling water is performed as described in section 5a2.2.5.

ating the PCLS cleanup side stream from the associated PCLS cooling loop for maintenance poses does not disrupt irradiation unit (IU) operation or prevent safe IU shutdown.

.5.5 PREDICTING, MONITORING AND SHIELDING RADIOACTIVITY PCLS cleanup side stream components are located entirely within the primary cooling room ociated with their respective IU cell. Each primary cooling room is located within the diation cell biological shield (ICBS). The ICBS provides a barrier to protect SHINE facility sonnel, members of the public, and various components and equipment of the SHINE facility educing radiation exposure. Refer to Section 4a2.5 for information pertaining to ICBS lding requirements. Radiation monitoring of the ICBS general area is provided as discussed ection 7.7.

LS does not discharge radioactive liquid effluent from the facility; therefore, there are no liquid ent monitors. Monitoring of closed loop process cooling water systems to detect cooling er leakage between primary and secondary circuits due to failures in heat exchangers and er system boundaries is provided.

discussed in Subsection 5a2.2.2, PCLS piping penetrating confinement boundaries are vided with isolation capabilities. Automatic isolation valves on the PCLS supply and return s exiting the IU cell are closed as part of an IU Cell Safety Actuation if the TSV reactivity ection system (TRPS) detects an outleakage of target solution into the primary cooling water.

hermore, the PCLS equipment is located inside the primary cooling room and IU cell, which shielded by ICBS. These design features limit exposure of personnel to radioactivity.

PCLS is a closed loop system and is operated at a higher pressure than the TSV to reduce potential for leakage of the target solution into the PCLS in the event of a breach. In the event ressurization of the primary system boundary, potential leakage from the TSV would be tained within the PCLS.

facility demineralized water system (FDWS) provides makeup water to the primary closed cooling system (PCLS), radioisotope process facility cooling system (RPCS), facility chilled er system (FCHS), molybdenum extraction and purification system (MEPS) hot water loop system, light water pool, and process chilled water system (PCHS). The FDWS provides a er supply to the radiological ventilation zone 2 (RVZ2) system and the facility ventilation zone VZ4) system for humidity control. The quality control and analytical testing laboratories BS) and the facility chemical reagent system (FCRS) are supplied demineralized water from FDWS. Operational cooling water loss in the PCLS and light water pool occurs gradually from olysis and evaporation. Water loss in the PCLS, RPCS, FCHS, MEPS hot water subsystem, PCHS may also occur from off-normal events such as leaks or for maintenance. Makeup the FDWS to the systems served is supplied through piping that contains backflow vention. Transfers of makeup water from the FDWS to the cooling and heating systems are ormed manually. Refer to Figure 5a2.6-1 for a flow diagram of the FDWS.

FDWS is supplied water from the facility potable water system (FPWS). The FDWS consists reverse osmosis (RO) skid located outside of the radiologically controlled area (RCA). The skid is a packaged unit that contains pre-filters, piping, valves, pumps, and RO membranes upply RO water. The RO skid is located downstream of the backflow prevention device that as the system boundary between the FPWS and the FDWS. A portion of the demineralized er processed through the RO membrane is supplied to end users outside the RCA requiring treated water with the balance supplied to the RO storage tank located inside the RCA. A ond backflow prevention device is provided at the boundary where the FDWS enters the A.

FDWS includes two 100% capacity pumps. The two pumps are supplied water from the RO age tank that has been filtered by the RO membrane on the RO skid. The pumps circulate er from the RO storage tank to a ring header inside the RCA and back to the tank. Only one p is required to be operational for system service. Recirculated water is supplied directly to users requiring RO-processed water, and through deionizers to other end users requiring nized water. Table 5a2.6-1 identifies the RO-processed and deionized water end users.

FDWS components are listed in Table 5a2.6-2, including design codes and standards.

w from the RO skid is controlled by level instrumentation in the RO storage tank. Tank level is vided with high- and low-level alarms. Pressure is monitored at the outlet of the circulation p where high- and low-level alarms are provided. Sampling and trending of the system is ormed to detect malfunctions in the deionizer units and the RO skid. Sampling and trending ve to identify when replacement or repair is necessary.

FDWS is not safety-related. On loss of normal power, the pumps will not be operational, as FDWS is not relied on to provide water on loss of normal power.

ogen-16 (N-16) is generated in the PCLS and light water pool by the neutron activation of gen. The N-16 control is provided by the primary closed loop cooling system (PCLS) delay ks. As shown in Figure 5a2.2-1, one liquid delay tank is located downstream of the air arator, in the PCLS cooling loop flow path, and the other is a gaseous delay tank located nstream of the PCLS expansion tank, inside the primary confinement boundary.

N-16 delay tanks provide additional holdup time to allow for sufficient decay of N-16 prior to ing the shielding to meet with as low as reasonably achievable (ALARA) goals and the ation protection program. In addition, to allowing a portion of the N-16 to decay, a reduction in lding wall thickness is realized as well as a reduction in the PCLS equipment radiation rance requirements.

PCLS uses an air separator to remove entrained gases from the cooling water flow path.

PCLS air separators are vented to the headspace of the corresponding IU cell expansion inside the primary confinement boundary. The headspace of the PCLS expansion tank epts separated gases, including N-16, and directs those gases to the gaseous delay tank, ugh the primary confinement boundary, and into the radiological ventilation zone 1 exhaust Z1e). Redundant safety-related isolation valves are provided on the flow path between the eous N-16 delay tank and the RVZ1e interface with the PCLS.
