ENVIRONMENTAL MONITORING As a result of changes in Technical Specifications, sampling milk for 131I~was dis-continued on September 21, 1973.
Thirty-nine (39) samples were obtained durina the first cuarter from the perimeter monitoring stations and were analyzed for alpha and beta activity. The alpha activity ranged from 1.38 (10 16) to 7.72 (10 16) uCi/ml for an average of 2.48 (10 16) uCi/ml.
The beta activity ranged from 1.90(1015)to4.63(1014) uCi/ml with an average of 1.61 (1014) pCi/ml.
LOW LEVEL LIQUID EFFLUENTS The amounts of radioactivity in liquid discharged from the plant curing this period and their relationship to the maximum permissible concentration (MPC) in the Cattaraugus Creek are shown in Table 1.
GASEOUS EFFLUENTS -
The amount of particulcte radioactivity discharged via the plant stack and the relationship to the release limit in the Technical Specifications is shown in Table
- 2. Change 20 to the Technical Specifications discontinued the recuirements of.
Krypton-85 and Iodine-131 monitoring while plant operations are suspended.
SURVEILLANCE TESTS During this period, tests were performed in accordance with Section 6 of the Technical Specifications. The completion dates are shown in Tables 3 and 4.
LOW LEVEL LIQUID WASTE TREATMENT PLANT PERFORMANCE During this period, the LLWT was.in operation a total of 24 days and treated 1,690,000 gallons of water. Ninety-six (96) drums of concentrated sludge were removed, each having a radiation level of <10 mr/hr. Decontamination of waste water continues to be good. All water discharged has been,below 2.0 x 10~5 pCi Csl37/ml. Average removal factors for this period are shown below.

J NUCLEAR FUEL SU!HARY The following information is based upon nuclear material accountability records and indicates the disposition of nuclear material in fuel at the reprocessing plant.
A. INVENTORY The total on-site inventory on March 31, 1980 was 166,759 kilograms of uranium and 1,039,827 grams of plutonium. An inventcry description by source and material type is presented in Table-5.
B. RECEIPTS AND SHIPMENTS During the quarter, there were no shipments or receipts of spent fuel assemblies at the West Valley site.
~
C. MEASURED WASTE AND ADJUSTMENTS There was no loss of uranium or plutonium during the reporting period as measured waste.
No adjustments for uranium and plutonium to NFS Lot 27A were required.
~
D. LOSS ON DECAY During the period 9/30/79 - 3/31/80, there was a reduction of 1,933 grams of plutonium in stored fuel due to the radioactive decay of the Pu-241 isotope.

. FACILITY PERF0Pf4ANCE AND MODIFICATIONS This section describes:
1.0 Major modifications that were either initiated or completed at the processing plant during the reporting period.
1.1 A new 6" steam line was installed which connects the discharge of a temporary boiler to the 150# steam header in the Utility Room. (See Section 2.1 below.)
2.0 A description of malfunctions of any equipment listed in Appendices 5.2. 9.51, 9.53 and 9.56 of the Final Safety Analysis Report which ,
are important to safety. l l
2.1 On January 14 at 1100 hours0.0127 days <br />0.306 hours <br />0.00182 weeks <br />4.1855e-4 months <br />, the north boiler experienced an l explosion in the fire box which damaged the boiler and the
, associated piping which was common to both boilers. Piping repairs were started immediately so that by 2100 hours0.0243 days <br />0.583 hours <br />0.00347 weeks <br />7.9905e-4 months <br /> the south boiler was producing steam.
On January 23, a rental boiler was received and set in place.
Installation and testing of the rental boiler were complete by February 12.
2.2 On March 3, the south boiler shut down at approximately 1545 hours0.0179 days <br />0.429 hours <br />0.00255 weeks <br />5.878725e-4 months <br /> due to a shorted alternator which supplies power for the boiler circuitry. The rental boiler was placed on line until temporary repairs were made to the south boiler to get it back on line at 2210 hours0.0256 days <br />0.614 hours <br />0.00365 weeks <br />8.40905e-4 months <br />.
On the following day the rental boiler was again placed on line until permanent repairs were made to the south boiler.
The south boiler was back on normal service at 1500 hours0.0174 days <br />0.417 hours <br />0.00248 weeks <br />5.7075e-4 months <br />.
