4 The content of the maintenance procedures appeared to be technically adequat The inspector reviewed 32 maintenance requests (MR) performed in connection with safety-related systems. The inspection indicated the following:

. Each MR had'the required administrative approvals prior to initiating the work, and the limiting conditions for operation (LCO)

were met while the components or system were out of servic Functional . testing and calibrations as necessary were completed prior to returning the equipment to. service. Quality Control l records were completed and inspections made in accordance with the

'

M The corrective and preventive MRs were assembled and stored as part of the maintenance histor The MRs were properly reviewed and approved to , assure adequate corrective action had been performed. .The licensee's long term j corrective action program to prevent irecurrence appeared to be

_

effectiv .

The licensee's' maintenance' program appeared to be technically adequate and' administratively correct. The maintenance procedures were followed as required during safety-related work and requests were reviewed to ensure adequate corrective' action had been performed. The long term corrective action program to prevent recurrence -appeared to-be ef fective.

No violations or deviations were identifie . Design, Design Changes and Modifications,Progra'm The licensee's design changes / modifications program was examined by the inspector and discussed with cognizant personnel. The inspector reviewed selected design changes and modifications to assure that the changes had been, reviewed and' approved in accordance with 10 CFR 50.59. The design changes and modifications had been evaluated in accordance with the program, and it was determined that they did not (a) inc'rease the l probability of occurrence of an accident or malfunction of'the equipment important to ' safety, as previously evaluated in the Trojan Final Safety Analysis Report (FSAR), (b) create the ' possibility of an accident or malfunction of a,different type than previously evaluated in the FSAR, or (c) reduce' the margin of safety as defined in the basis for any Trojan Technical-Specification.

'

The inspector reviewed 15 plant modifications and design changes and the inspection results were as follows:

. The design changes / modifications were. reviewed _and approved in accordance with Trojan Technical Specifications and established

QA/QC controls. Only two Plant Design Changes involved changes to

'

the Trojan Technical Specifications. Plant Design Change 81-045,

initiated as a result of a control room habitability review which

, identified sulphur. dioxide transported by railway as'a potential hazard to the control' room operators, authorized the installation of redundant sulphur dioxide detectors in the control room ventilation system. The detectors will alarm and isolate the control room ventilation system at a level adequate to protect personnel. This modification resulted in the' addition of the detectors to Trojan Technical Specifications, b'ut did not involve an unreviewed safety question. Another similar Plant Design Change 81-046, initiated again as a result of a' control- room habitability review which identified ammonia transported by railway as a potential hazard to control room operators, also resulted:in the installation of redundant detectors in the control room ventilation system. These detectors will alarm and isolate .,the ' control -room ventilation system at a level adequate to protect personnel. These detectors have also been added to the Trojan Technical Specification The design changes / modifications reviewed were verified to be controlled by established procedures. A review of the completed test records indicated that the licensee conducted a review and-evaluation of test results to ensure that the test results were within previously established acceptance criteri The inspector verified that the as-built drawings were changed to reflect the modifications. In addition, operating procedure modifications were revised and approved in accordance with the Technical Specifications for those design changes / modifications selecte The licensee's design changes / modifications program appeared to be technically adequate and was being conducted in accordance with the approved procedures. Acceptance and startup testing appeared to be technically adequate and conducted in accordance with approved test procedure No violations or deviations were identifie . Follow-up on Previous Inspection Findings (Enforcement Item 85-08-01; Closed) Procedure Violations of Maintenance Program

+

The Testing / Installation Results section of several maintenance request (MR) forms had been lef t blank and unsigned after the completion of quality-related maintenance and that work performed for MR 84-1136 was beyond the scope of the applicable work instruction The licensee responded via PGE letter dated April 22, 1985, and stated that all of the MRs identified which have' inadequate testing documentation have been reviewed to ensure that appropriate testing was performed on the equipment upon its return to service to assure

, its ability to function as required. Documentation of that testing has subsequently been included with the applicable MR for e

incorporation into the Plant Equipment History Files. The

" Testing / Installation Performed By" sections have now been signed and date It was verified that all work ~ performed by MR 84-1136 had been reviewed and approved. Documentation of that work has been completed. When the service water booster pump motor resistance readings were found by the craftsman to be low, the MR was returned to the Electrical Foreman for further instructions. The craftsman was then verbally directed to remove the motor for reconditionin '

However, these additional instructions were inadvertently not added to the M The licensee stated that the root cause of this Notice of Violation has been determined to be the result of procedural noncomplianc Adequate procedures exist to require the documentation needed in support of the activities performed above. Therefore, as corrective action, a review of these occurrences was conducted with the

'

- appropriate personnel to reemphasize the need for and importance of complete documentation of maintenance activitie The' inspector verified that the licensee had corrected the subject MRs' by signing and dating in the " Testing Installation Performed By" sections and included testing documentation. .The inspector verified that MR 84-1136 has been completed with the missing instructions as necessary to remove the service water booster pump motor for reconditionin ,

Item 85-08-01 is c16 se s (Deviation item 85-08-02; Closed)'NUREG-0737/I.A.2.3 Deviation-Overtime

.

NUREG-0737, item I.A.1.3 states that an individu'al should not be permitted to work more than 72'ho'urs'in any seven day period and that any deviation'from this guideline shall be authorized by the plant manager,' or his deputy or higher levels of managemen '

The appropriate overtime. authorization: had not b'een"made for,nine employees. These individuals werd[ covered by two " blanket ~

deviations" approved by the appropriate' levels of management and in accordance with plant procedures for this period of time. The

'

licensee's response was via.PCE letter dated April 22, 1985, which stated that PGE asked for and received clarification of the work hour limits required by the'NRC. NRC confirmed that work hour restrictions apply to " members of_the plant staff who perform

~

safety-related functions." It was. confirmed'that the personnel referenced in the, Notice of Violation, with the exception of one individual, were all working on safety-related components and subject to the criteria of NUREG-0737.'

The inspector confirmed that, since the 1984 outage, PGE has changed ,

the work limit (overtime) policy to require deviation approval fo all personnel for each instance of deviation, regardless of the type

area in the futur Item 85-08-02 is close (10 CFR 21 Report 84-00-P; Closed) BBC Br'own Boveri Inc. Voltage Balance Relay (ITE-60)

The resultslof the licensee's operational assessment review by the control and electrical department indicates that they do not have any BBC Brown Boveri Madel ITE-60 voltage balance relays in the plant. Based on these negative findings, 10 CFR 21 Report 84-00-P is close . IE Bulletins, Circulars, and Notices Followup The ins'pector conducted a review of IE Bulletins, Circulars, and Notices to the licensee's response for technical adequacy and implementation of corrective action (s). The following IE Bulletins, and Notices were determined to be closed:

A) IEB 79-24 Upgrade needed to heat trace - The modifications have:been completed to alleviate the effects of adverse weather conditions for the facada area between the containment and turbine building. The weather proofing at the 69 foot elevation slab and weatherization of electrical boxes has been complete B) IEN 84-83 Various Battery Problems - Per discussion with the licensee's control and electrical department personnel solvent is not used to clean the battery posts of anti-corrosion grease during rework of the intercell connections, instead rags and brushes are use ,

The licensee does keep' track of the D? loads on the battery and ~any additional' loads added. By tracking DC loads, the licensee has'not overloaded the DC buses with the available DC batter . Exit Interview The inspector met with the 1censee representatives denoted in paragraph 1 on May 17, 1985, and summarized the scopeiand findings of' the inspection activitie .
