pressure turbine overhaul; and replacement of resistance temperature detector (RTD) manifold On October 7,1987, a contract worker fainted while working on the Unit 2 B steam generator. He was wearing a respirator and anti-contamination clothing. The respirator and protective clothing were removed at the plant and he was taken by ambulance to a local-hospita The worker had slight amounts of radioactive contamination on his socks, face, and hair (9,000 - 15,000 disintegrations per minute over 100 square centimeters). The contamination.apparently occurred when his respirator and protective clothing were remove He was accompanied to the hospital by plant health physics personnel. He was decontaminated there by the health physicists and examined by medical personnel. He was released and returned to work within several hour The ambulance and hospital treatment area were surveyed, and no detectable radioactive contamination was foun The licensee received a letter from Westinghouse detailing the possible susceptibility of the Unit 2 steam generators to the type of failure which occurred at the North Anna plant. The licensee was asked to perform inspections to determine if there was tube denting at the upper tube support plate and to what extent the antivibration bars penetrated the tube bundle. The licensee performed these inspections and provided the results to Westinghouse for analysis. Preliminary results indicate that the steam generators have no tubes at risk. This information will also be presented to NRR in a meeting scheduled for the first week of Novembe No violations or deviations were identifie . Monthly Surveillance Observation (61726)

The inspector observed technical specifications required surveillance i testing on the Reactor Protection and Safeguards Analog Channels and j Nuclear Instrumentation and verified that testing was performed in accordance with adequate procedures, the test instrumentation was calibrated, that limiting conditions for operation were met, that removal and restoration of the affected components were accomplished, that test results conformed with technical specifications and procedure requirements and were reviewed by personnel other than the individual directing the test, and that any deficiencies identified during the testing were properly reviewed and resolved by appropriate management personne The inspector also witnessed or reviewed portions of the following test activities:

No violations or deviations were identifie . Physical Security (71881) j

The inspectors, by observation and direct interview, verified that physical security was being implemented in accordance with the station security pla {

!

During the inspection period, the inspectors verified that the security )

force compliment was as required by the security plan, that search {

equipment was operational, and that access control for personnel and {

packages was implemented in accordance with licensee procedure The i inspectors verified that the protected and vital area barriers were being well maintained and, when required, appropriate compensatory measures were take No violations or deviations were identifie . Radiological Protection (71709)

During the inspection period, the inspectors verified that health physics i supervisory personnel conducted plant tours and were aware of activities l which may cause unusual radiological conditions. The inspectors verified '

that radiation work permits (RWP) contained required information and for selected RWPs the inspectors verified controls were being implemented as i required at the work site. The inspectors observed personnel within i radiation controlled areas and determined that personnel monitoring I equipment was properly worn and that the licensee's procedures for entry j and exit were followed. The inspectors observed the posting of radiation i areas, hot spots, contaminated areas, and labeling of containers holding radioactive material and verified postings using a calibrated beta gamma portable survey mete i
