PREOPERATIONAL RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM AT FERMI-2 O MA QUARTERLY PROGRESS REPORT,1981-Q1 NNy IS8f 1.

Schedule Status The schedule of sampling of environmental media for the Fermi-2 REMP is shown in Table 1. A number in parentheses specifies the number of sampling trips to be made in the quarter; an X following the number in parentheses designates com-pleted sampling trips to indicate the schedule status.

2.

Summary of Work Accomphshed,1981-Q1 2.1 Duplicate thermoluminescent dosimeter (TLC) badges of four readout areas each were placed at thirty-seven locations on January 3,1981 through January 6,1981. These iLDs were picked up and replaced with freshly annealed dosimeters on April 11 and 12,1981.

The exposed dosimeters were returned to the NUS Radiological Laboratory for analysis. The results are presented in Table 2.

2.2 The results of the gross beta analyses performed on the individual air filters are listed in Table 3.

Analyses of composited filters for gamma emitting nuclides have not been performed, to date, because of counting equipment failure.

Gamma results will be promptly transmitted to Edison upon availability. An explaration of the equip-l ment problems and repair / replacement status is included in Section 5 of this report.

2.3 Three milk samples were collected from Station 7 (Doty Farm) during the quarter. The gamma results of the January and February samples are presented m Table 4.

The March sample has been counted; t

l l

nuclide quantifications have not been performed bect.use of hardware problems associated with the data reduction system. The status of the March milk sample is addressed in Section 5.

2.4 Surface weer samples from two locations and drinking water samples from one location were collected during the quarter. The results of analyses for gamma emitting isotopes are listed in Table 5. Table 6 presents the tritium concentrations of quarterly composites, by location. The results of gtoss beta analyses performed on the drink-ing water samples are presented in Table 7.

The status of the gamma results for the March water samples is equivalent to the March milk sample (refer to Section 5).

2.5 Contract No. l A-84520 (Edison /NUS) for the Fermi-2 REMP expired on March 31, 1981. Prior to expiration, NUS submitted Proposal No.

8103054 to Edison for contract extension through March 31, 1982.

Similar to last year, NUS is actively continuing an uninterrupted program for 1980-Q2 based on verbal assurance from Ms. E. Madsen that the contract will be extended. To comply with NUS corporate policy, a formal contract agreement with Edison is essential. NUS anticipates that Edison will expedite wr tten confirmation of the contract extension to preclude potential di'ficulties in the coming months.

2.6 During a review of the Fermi-2 monitoring sarnples, it became ap-parent that Mr. Carl Scheffler (one of two site technicians employed by NUS for the Fermi-2 REMP) was no longer able to comply with the specified schedules for sample collection or reporting requirements.

In order to avoid the potential for program jeopardy, Mr. Scheffler's employment with NUS was immediately terminated. A replacement will be ident;fied in June or July. During this interim, the other site technician, Mr.

Phil Vorva, will be performing sample collection activities and instrument maintenance.

Deviations from the Sampling and Analytical Regime Various hardware difficulties associated with the Tracor Northern Ge(Li) gamma detection system owned by NUS, began in March.

The original difficulty was traced to a faulty driver buffer which provides communication between the DEC LA-120 teletype and the main computer system. This problem was unique in that laboratory technicians were able to initiate sample counting and subsequent tape storage of the spectrum, but data analysis with hardcopy printout was not possible.

Af ter numerous contacts between NUS, Tracor Northern, and DEC, the defective buffer unit was identified and replaced in April.

Concurrent with the identification of the defective driver buffer, the entire computer system began to function on an intermittent basis. Ultimately, it became impossible to partition memory areas for data storage, initiate counting sequences, and other similar command sequences. After exter:sive consultation with Tracor Northern personnel, various replacement components were unsuccessfully used to r

3 NUS CORPORATION l

repair the system. The vendor's " trial and error" method of corrective action was f.(/

unacceptable to NUS so the entire system (hardware and sof tware) was shipped to the vendor in late May for an indepth assessment of all components. The system was returned to NUS in early June; outstanding data from 1981-Q1 will be submitted to Edison immediately upon availability.

The following table indicates the status of outstanding 1980-Q1 samples:

+ Match samples No January water sample was collected from Station 13 (City of Monroe-drinking water). The sample line had become detached from its connection with the water pipe; the site technician corrected the problem and initiated collection for the February composite sample.

From 12-28-80 through 1-22-81 no air particulate samples were collected from Station 5 located along Toll Road. The instrument was undergoing repairs from 12-2S-80 to 1-6-81. Although samples were ob:ained from 1-6-81 to 1-22-81, gross beta results were :iot reported because of uncertainties surrounding the air volumes.

During sampling activities on 1-22-81, the site technician encountered Edison personnei performing electrical work on the pole carrying power to Station 5. He was informed by these personnel that powt had been interrupted, but would be NUS CORPORATION 4

restored upon the completion of their work later that day. To date, power still has not been restored to Station 5.

The site technician placed all power switches, within his control, to the "on" position so that the instruments would automatically restart with pown restoration. The status was verified each week during sampling activities to Station 4 which is also located along Tall Road. Edison has been advised of the initial and continued status by telephone and written notifications.

Air particulate samples were not collected from Station 7 for the period 3-24-81 to 3-31-81. The venturi tube was broken and the instrument was removed for repair.

Although the air sample envelope for Station 4, 3-24-81 to 3-28-81, was received in the laboratory, it did not contain the particulate filter.

'The site technician indicated in the field log that the sample was collected; it was apparently misp' aced by the technician.

1981-Q1 TLDs deployed at Station S,, S-II (1 of 2), S-24, and S-30 were missing at the time of collection as a result of vandalism. TLDs fcr 1981-Q2 were deployed at all loce.tions as scheduled.
