The Technical Specification 15.7.7.A.1 recognizes that certain I samples may be missed due to hazardous conditions and other legitimate circumstances. During January of 1991, ice buildup along the shoreline of Lake Michigan at location E 05 prevented the collection of water at this site. In the fourth quarter of I 1991, the TLD at location E 02 was moved when the ' Energy Center" sign to which it was attached was transplanted from the Site Boundary Control Center on 14uclear Road to the Enargy Inf ormation Center near the Plant. Health Physics was not notified of the .

I move. The TLD remained at the new location for one month before it was found, This TLD was not analyzed for the RE!4P.

The new fuel assemblies received for Unit 2 were used for the Fall 1991 refueling.

I There were no spent fuel shipments made from Point Beach Nuclear Plant during this reporting period.

5.0 RADIOLOGICAL ENVIRONMENTAL MONITORING Radiological environmental monitoring conducted at Point Beach Nuclear Plant from July 1, 1991 through December 31, 1991 consisted of air I

filters, milk, lake water, well water, soil, fish, shoreline sediments, algae, vegetation, and TLDs.

.. 1

I-No significant deviations from nottnal results, attributable to the operation of the Point Beach Nuclear Plant, were identified during this six month reporting period. However, above normal H 3 concentrations I were found in Lake Michigan water samoles obtained north of PBNP.

Because the concentrations increase away from PBNP, the elevated H 3 concentrations are not the result of PBNP operations. Low levels of Sr 90 and Cs 137, resulting from Chernobyl and atmospheric weapons tests, still persist in milk (Sr 90) as well as in fish, sediment, I algae, and soil (Cs 137) samples. All TLD results were within the normal range for the third and fourth quarters of 1991.

In July, visual verification of anisaals grazing in vicinity of the PBNP I site boundary, pursuant to Technical Specification 15.7.7.D, determined that the milk sampling program remains as conservative as practicable.
