~O 321.26 It is indicated in Table 6.5-1 of the FSAR that the ESF air (6.5) filtration systems are designed to applicable temperature, radiation dose rate, pressure, and seismic considerations in accordance with Regulatory Guide 1.52, Rev. O, and postulated DBA conditions. Table 6.5-1 does not indicate whether relative humidity was considered in the design of the systems as re-quired by regulatory position C.1.a of Regulatory Guide 1.52.

Indicate how relative humidity was considered in the design of ESF air filtration units.

321.27 Table 6.5-1 of the FSAR does not address whether the essential (6.5) services such as power and electrical control cables of the ESF air filtration systems are adequately shielded fro.n the atmosphere cleanup systems as required in regulatory position C.1.b of Regulatory Guide 1.52.

Indicate whether such shield-ing is available for the essential services and justify any deviations from position C.1.b.

321.28 Based upon our review of ESF air filtration systems in (6.5, Sections 6.5 and 7.5.1, it is our understanding that pressure 7.5) drops across the prefilter and HEPA filter and across the filter train are indicated locally and recorded in the main control room.

It is our position per C.2.g of Regulatory Guide 1.52 that the flow rates through the ESF air filtration system must also be recorded in the main control room.

321.29 Since the charcoal adsorbers of the ESF air filtration systems (6.5) do not have water sprays, it is our position that the plant must have some means, such as described in Regulatory Guide 1.52, Rev. 2, to extinguish ignited charcoal.

Describe the method the Waterford 3 plant utilizes to extinguish charcoal fires.

321.30 Document in Table 6.5-1 that your ESF air filtration systems (6.5) compiy-with regulatory positions 4h-4m of Regulatory Guide 1.52, Rev. O.

321.31 Describe the fuel handling building ventilation ~ system's.

(6.5) and the control room air conditioning system's capability to handle pressure surges as required by regulatory position C.2.d of Regulatory Guide 1.52.

321.32 From Section 11.3 of the FSAR and your response to question 321.10 (11.3) it appears that H /02 monitors are sequential monitors and are 2

not dedicated to the continuous monitoring of the H2 and/or 02 content in the waste gas system.

It is our position, as indicai.ed in SRP 11.3, that a continuous analyzing monitor, either H2 or 02 is required between the waste gas compressor and the gas decay tanks.. The sequential analyzer may be used as the backup analyzer, which will serve the dual requirement in SRP 11.3, but continuous measurement and alarm capabilities is required at all times.

321.33 Based upon conformance with General Design Criteria 64 of (11.5)

Appendix B to 10 CFR Part 50 and Standard Review Plan 11.5, it is our position that the effluent monitoring instrumenta-tion requirements for Waterford 3 will include those monitors presented in Tables 321.33-1 and 321.33-2.

321.34 In Table 11.5-1 of the FSAR the radiation monitor of the SGB (11.5, system does not appear in Drawing G-162,' Sheet 2 as indicated 9.5) by the Tabie. Likewise, the radiation monitor of the conden-ser vacuum pumps does not appear in Drawing G-153, Sheet 1.

Provide revised drawings or a verbal description of the lo--

cation of these monitors.

In addition, the fuel handling building radiation monitors RE-HV-5107A and RE-HV-5107B are not shown in Figure 9.4-2 nor are they indicated in Table 11.5-1.

Provide information as to the location of these monitors in addition to a description of their alarm function, recording location, range, sensitivity, etc.

321.35 Section 11.2.2.3 of the FSAR indicates that waste collected (11.2) in the regenerative waste tank and the filter flush tank will normally be discharged to Waterford's Units 1 and 2 metal waste pond.

Identify the concentration or total amount of radioactive material in this waste above which processing in the radioactive solid waste system will be required and describe the bases on which this level was determined.

321.36 Section 11.5.2.4.2.3 of the FSAR znd Figure 9.3-3 indicate (11.5, that all turbine drains will be routed to industrial waste 9.3) sumps 1 and 2.

During normal operation, these wastes are to be discharged through a radiation monitor and an oil separator to the circulating water discharge canal. However, in the case of a detection of high radioactivity, this waste is diverted to the waste tanks of the liquid waste management system to be processed by the waste concentrator and the waste condensate ion exchanger. Discuss the impact of these oily wastes upon operation of the waste concentration and waste condensate ion exchanger and in particular the DF's of the equipment.
