(Activity > 2x control.)

The predominant wind direction has been indicated for the sample periods and possible correlation with on-site releases has been noted.

3) TLD's - Table 15 The environmental TLD readings are reported as an average of 5 individual chips at each location.

The TLD's are broken down into 3 groups for inclusion in this report. These groups and their respective quarterly averages are as follows (mr/qtr):

QUARTERLY AVERAGES 1 2 3 -

On-Sites 45.4 48.8 59.8 35.1 Badges 31, 32 and 39 are located near the NMP Radwaste Building and are being influenced by the waste trucks being loaded in the area. Badges 29 and 30 are probably being effected by the JAF N-16 gamma radiation or "turbine shine" and also by, waste trucks being loaded in the area.

~ t inches. These valves will be tested through full trave distance during each refueling interval.

Basis The safety injection system and the containment spray system are principal plant safeguards systems that are normally operable during reactor operation.'omplete system tests cannot be performed when the reactor is operating- because of their inter-relation with operating systems. .The method of assuring oper- .

ability of these systems is a combination of complete system tests performed during refueling shutdowns and monthly tests of active system components (pumps ,

and valves) which can be performed during reactor operation. The test interval is based on the judgment that more. frequent testing would not significantly increase the reliability (i.e., the probability that, the component would operate when required), yet more frequent tests would result in increased wear over a long period of time.

The monthly part travel exercising of the VCT outlet to charging pump suction valves, in lieu of the full travel exercise, is conducted to preclude an inter-ruption of, normal plant operations. Redundant valves have been used to assure proper lineup in the event, of ECCS actuation. Other ECCS valves whose operation is not required to assure core flooding or containment spray shall be tested during each refueling shutdown period in accordance with 2.b.

Verification that the spray piping and nozzles are open will be made initially by a suitably sensitive method, and at 'least every five years thereafter.

Since all piping material is all stainless steel, normally in a dry condition,,

and with no plugging mechanism available, the retest every five years is considered to be more than adequate.

Other systems that are important to the emergency cooling function are the SI tanks, the component cooling system and the service water'ystem. -The SI tanks are a passive safety feature. In accordance with the Specification 4.1 (Table 4.1-2, I em ll), the water volume ard pressure in the SI tanks are checked periodically. The component cooling and service water systems operate when the reactor is in operation and are continuously monitored for satisfactory performance.

The three month testing interval of the steam generator auxiliary feed pumps verifies their operability by recirculating water to the demineralized water tank.

Proper functioning of the steam turbine admission valve and starting of the auxiliary feed pump will demonstrate the operability of the steam driven pump.

Verification of correct operation will be made both from instrumentation with the main control room and direct visual observation of the pumps.

The main steam, excess flow check valves serve to limit an excessive reactor.

coolant system cooldown rate and resultant reac"ivity insertion following a main steam break incident. Their freedom .to move will be verified periodically.
