,3 REQUEST FOR ADDITIONAL INFORMATION WASHINGTON PUBLIC. POWER SUPPLY SYSTEM '

NUCLEAR POWER PROJECT NO. 3 - UNITS 3& 5 DOCKET NUMBERS 50-508 AND 50-509 METEOROLOGY 322.01 Provide the maximum winter precipitation (2.3.1) (snow and/or rain) amount, in water equi-  ;

valent, for a single storm with a recurrence interval of 100 years in the vicinity of the site.

322.02 If the period of record for snow pack (2.3.1) observations at Oakville is less chan 100 years, provide additional j ustifica-tion for using a value of 25.2 inches for the 100-year recurrence interval snow pack depth in view of the observed 27 inch depth at Oakville.

322.03 Provide the weight (in pounds per squ're a (2.3.1) foot) or the water equivalent (in inches of water) for the 100 year recurrence in-

- terval snowpack.

322.04 Provide an estimate of the seasonal and l (2.3.1) annual frequencies of cloud to ground lightning discharges (based on the o'ccurrence of thunderstorms) in the site area.

322.05

• Provide and substantiate the meteorological (2.3.1) data used for the ultimate heat sink, con-  !

sidering:

1. Maximum evaporation and drift loss and

2. Minimum water cooling 322.06* Provide the design basis wet-bulb temperature (2.3.1) and any other design basis meteorological para-meters used for the cooling tower system and include appropriate cross-references.

• Indicatan information needed for LWA assessment.

.. 322.07- Provide any other meteorological conditions (2.3.1) used as design or operating basis conditions-for the plant, such as.the maximum snow and ice load (in wate r equivalent) that the roofs of safety related plant structures are capable of. withstanding during plant operations, and include appropriate cross-references.

^

322.08 Since "all available plume length models, in-3 (2.3.2) cluding the one used in the PSAR, are empirical in nature and have experienced minimal verifi-cation" (refer ~ence Section 2.3.3.2), provide a discussion of the representativeness of Baker's empirical plume length formula as used for the site. Include any plans to verify the model using onsite observations of meteorological condi-tions and indications of icing on the meteorolog-ical tower or other plant systems.

322.09 Provide a description of the lightning protection (2,3.3) system on the onsite meteorological tower an'd

• any other provisions for reducing outage time due to failures caused by lightning discharges.

322.10 Table 2,3-61 does not show th's calib' ration /mainten-(2.3.3) ance procedure for the wind speed neasuring system.

P ro vi d e informati,on concerning the calibration and maintenance procedures for this system. In addi-tion, provide the maintenance schedule for the meteorological system including sensors, recorders data procesoing components.
