The inspectors observed and reviewed Technical Specification required L

surveillance testing and verified that testing was performed in accordance

'with adequate procedures; that test . instrumentation was calibrated; that limiting conditions were met; that test results met acceptance criteria and

-

were reviewed by personnel other than the individual directing the test; that any deficiencies identified ~during the testing were properly reviewed

'

and resolved by appropriate management personnel; and that personnel conducting the tests were qualifie The inspector witnessed / reviewed portions of the following test activities:

Investigation revealed that the breaker charging motor for closing the breaker would not operate due to 'an inoperable micro switc A roll pin which holds the actuator arm in place had slipped out. The breaker was repaired, tested and returned to operable statu The breaker is a Siemens-Allis, MA-350C, air magnetic circuit breaker. The micro switch is a Square D Class 9007 type CB industrial snap switch. The licensee discussed this with Siemens-Allis and Square D Compan Both vendors describe the problem as isolated and non generi The licensee has modified the 4160V breaker preventative maintenance procedure to include a step to inspect the micro switch. The licensee has initiated an inspection of the breakers. To date 12 breakers have been inspected. No further problems have been found. The licensee has issued a memo and instruction in the Night Order Log Book to operating personnel to physically check each breaker af ter cycling the breaker closed and open in order to verify that the charging motor has functione No violations or deviations were identifie . Monthly Maintenance Observation (62703)

Station maintenance activities of safety-related systems and components were observed / reviewed to ascertain that they were conducted in accordance with approved procedures, industry codes and standards, and were in conformance with regulatory requirement The following items were considered during the review: limiting conditions for operations were met while components or systems were removed from service; approvals were obtained prior to initiating the work; activities were accomplished using approved procedures and were inspected as applicable; functional testing and/or calibrations were performed prior to returning components or systems to service; quality. control records were maintained; activities were accomplished by qualified personnel; parts and

~

materials were properly certified; radiological controls were implemented; and fire prevention controls were implemented. Work requests were . reviewed to determine the status of outstanding jobs to assure that priority was assigned to safety-related equipment which may affect system performanc The following maintenance activities were observed / reviewed:

4 Operational Safety Verification (71707)

.

.The inspectors observed control room operations, reviewed applicable logs and conducted discussions with control room operators during the report period. The inspectors verified the operability of selected emergency systems, reviewed tagout records, and verified proper return to service of affected ccmponents. Tours of the auxiliary diesel, and turbine buildings

were conducted to observe plant equipment conditions, including fluid leaks

and excessive vibrations. The inspector verified compliance with selected Limiting Conditions for .0perations (LCO) and results of selected surveillance tests.. The verifications were accomplished by direct observation of monitoring instrumentation, valve positions, switch positions, accessible hydraulic - snubbers, and review of completed logs, records,.and chemistry results.

c The inspectors routinely attended meetings with certain licensee management and observed various shift turnovers between - shif t supervisors, shift

, foremen and licensed operators. These meetings and discussions provided a

{ daily status of plant operating, maintenance, and testing activities in progress, as well as discussions of significant problems.

Tte inspector verified by observation and interviews with security force

members that measures taken to assure the' physical protection of the facility met current requirement Areas inspected included the organization of the security force; the establishment and maintenance of gates, doors, and isolation zones; access control and badging and procedures.

No violations or deviations were identified.

T' Licensee Event Reports d

The following Licensee Event Reports (LERs) were reviewed for potential generic problems to determine trends, to determine whether information included in the report meets the NRC reporting requirements and to consider

whether the corrective action discussed in the report appears appropriate.

'

Licensee action, with respect to selected reports, were reviewed to verify that the event had been reviewed and evaluated by the licensee as required

, by the Te'chnical Specification; that corrective action was taken by t.he licensee;~and that safety limits, limiting safety setting and LCOs were not exceede The inspector examined selected incidents reports, logs and records and interviewed se.lected personnel .

. Unit 1 LER-86-01 - Technical Specification Action Statements Not Met When R-11 Was Inoperabl Unit 2 LER-85-15 - Nuclear Instrumentation System Rate Trips Inoperabl . Followup Of Plant Events (92702)

On ' February 28, 1986 at 4:26 p.m. , Unit 1 tripped from 10R% power on a neutron flux high negative rate trip signal. The negative rate trip occurred when rod F 'O in group 2 of control bank "D" dropped into the core. The cause of the dropped rod was a blown fuse in the stationary gripper coil circuit. The fuse blew as a result of a short in the electrical penetration associated with rod F-1 The wiring was moved to another set of penetration leads and returned to operation. The unit was . restarted on March 2,198 All systems functioned as designed. The engineered safeguards systems were not challenge No violations or deviations were identified.
