The inspector reviewed the following completed work packages:
(1) Unit 2, WR 793, Unit 2 Diesel generator crankcase high pressure switch; (2) Unit 2/3, WR 647, Standby gas treatment system air lenk; and (3) U it 3, WR 4027, SRM pulse pre-amplifier, WR 4791, 125 VDC ground isilation.
No items of noncompliance were identified.
3.
Plant Operations The inspector reviewed the plant operations including exami-nations of control room log books, routine patrol sheets, shift engineer log book, equipment cutage logs, special operating orders, and jumper and tagout logs for the month of July, 1979.
The inspector observed plant operations during five offshifts during the month of July, 1979. The inspector also made visual observations of the Ioutine surveillance and functional tests in progress during the period.
This review was conducted to verify that facility operations were in conformance with the requirements established under Technical Specifications, 10 CFR, and Administrative Procedures. A review of the licensee's deviation reports for the period was conducted to verify that no violations of the licensee's Technical Specifications were made. The inspector conducted a tour of Units 1, 2 and 3 reactor buildings and turbine buildings throughout the period and noted that the monitoring instrumentation was recorded as required, radiation controls were properly established, fluid leaks and pipe vibrations were minimal, seismic restraint oil levels appeared adequate, equipment caution and hold cards agreed with control room records, plant housekeeping condi-tions/ cleanliness were adequate, and fire hazards were minimal.
The inspector observed shift turnovers to verify that plant and component status and problem areas were being turned over to relieving shift personnel. The inspector observed sampling and chemical analysis of water chemistry samples to verify that water chemistry was being maintained in accordance with Technical Specifications.
No items of noncompliance were identified.
4.
Physical Pr(Jection - Security Organization The inspector verifiud by observation and personnel interview (once during each operating shif t) that at least one full time member of the security organization who has the authority to direct the physical security activities of the security organi-zation was onsite at all times; verified by observation that the security organization was properly manned for all shifts;

and verified by observation that members of the security organi-zation were capable of performing their assigned tasks.
There
.
were no weapons qualifications conducted during this monthly inspection.
No items of noncompliance were identified.
5.
Physical Protection - Physical Barriers The inspector verified that certain aspects of the physical barriers and isolation zones conformed to regulatory require-ments and commitments in the physical security plan (PSP); that gates in the protected area were closed and locked if not attended; that doors in vital area barriers were closed and locked if not attended; and that isolation zones were free of visual obstructions and objects that could aid an intruder in penetrating the protected area.
No items of noncompliance were identified.
6.
Physical Protection - Access Control (Identification, Authorization, Badging, Search, and Escorting)
The inspector verified that all persons and packages were identified and authorization checked prior to entry into the protected area (PA), all vehicles were properly authorized prior to entry into a PA, all persons authorized in the PA were issued and displayed identification badges, records of access authorized conformed to the PSP, and all personnel in vital areas were authorized access; verified that all persons, packages, and vehicles were searched in accordance to regulatory require-ments, the PSP, and security procedures; verified that persons authorized escorted ace, were accompanied by an escort when within a PA or vital area; verified that vehicles authorized escorted access were accompanied by an escort when within the PA; and verified by review of the licensee's authorization document that the escort observed above was authorized to perform the escort function.
