. ms-2 0 MT1 D. J. Skovholt, Assictant Director for Reactor Operations, DRL JERSEY CEITIRAL TGIER & LIGHT'COIFANY.- OYSTER CREEK, C0 REPORT ID. 219/71-1 The' enclosed report of inspections of the subject facility on April t-8, a nd ' 12-13, 1971, is forwarded for information.

Several deficiencies involving noncompliance or safety consideratione were identified during these inspections. The most significant of these are as follows:

A 'nonconcervative error of a factor of approximately 2 5 was found in a.

the calibration of the laboratory gross beta analyzer used in determin-ing radioactivity in liquid effluents.

This error is caused by the e

failure to apply the proper geometric correction factor to the calibra-tion calculations.

~b. 'An additional nonconservative error of a factor of approximately three (3) was identified in comparing the total activity as determin:d by icotopic ana. lyses (beta + gamma) of liquid vaste samples with the total activity-determined by gross beta analysis after applying an appropriate correction factor for gross beta counter geometry (see a. above).

Applying the correction factors discussed above to the 1970 liquid c.

effluents indicates that the annual av9 rage concentration of unidentified radionuelides was in excess of 1 x 10~ uC1/ml. The licensee is current-ly reviewing 1970 liquid effluents to develop an appropriate correction factor.

d.

A review of the operation of the in-line liquid.vaste monitor indicates that it does not perform itc intended function and has not been capable

}

of detecting the errors in the laboratory analyses.

The performance of the liquid vaste system is not meeting design objectives e.

to. limit radioactive effluents from the plant. System design objectives specified that vaste collection drains are " essentially always reused as condencate"; however, more than 90% of this water was released to the circulating vator' system during 1970. Furthermore, the system evaporator l

' has not been utilized to the. extent practicable.

!* 5 D. J. Skovholt We are currently reviewing our findings and expect to iccue an enforcement letter to the licencee in the near future.

Although the deficiencies identified during the inspection reflect adversely on the procedures for handling and processinc radioactive liquid wabtes, we do not concider that this reflects a general breakdown in management controls or a change in the positive attributes manifested by company management dur-ing our October 1970 $ nspection of management controls (CO Report No. 219/70-8).

The deficienciec which were observed are typical of those which we are finding at a number of other facilities during our current in-depth review of effluent monitoring and effluent control procedures at operating power reactors. With 2egard to the specific deficiencies detected, we have confirmed that appropriate corrective meacurec have been or are being implemented.
