The subject of housekeeping has been an ongoing inspection topic?of the resident inspection program. Therefore, this' item is considered close (Closed)~ Followup Item =50-361/81-09-03, Calculation of component cooling water heat exchanger performance The inspector examined the documentat' ion associated with this item and verified that the initial indications of unsatisfactory preoperational test results were properly evaluated. The test

, results were ultimately determin'de to be acceptable. The initial unsatisfactory indications were apparently caused'by . local temperature indicators which did not extend sufficiency into the l

active salt water flow path'to obtain valid temperature l measurements. Design change package (DCP) 267J was issued and l implemented on January 11, 1985, to rectify this. Therefore, this

! item is considered closed.

The licensee now has in place a Retest Manual, S023-XV-1.0, Revision 0, dated March 5, 1984, which appears to be a compreheasive list of tests required for various types of components, both electrical and mechanical, and includes specific retest requirements by reference to specific test procedures or portions thereof. This item is considered closed based on licensee action . (Closed) Followup Item 50-361/82-17-01,. Inadequate Implementation of ANSI N45.2.6 and SNTC-1A Inspection Requirements for Rigging Equipment This item described licensee procedural deficiencies in that the licensee procedures at the time did not specifically require that personnel performing periodic non destructive exarainations (NDE) of rigging equipment be formally qualified for ND The inspector examined the applicable procedures S0123-I-).10 and 7.14 and verified the proper requirements had been incorporate This item is considered close m. (Closed) Followup Item 50-361/82-32-01, Requalification Training Records The subject area described by this item was examined and found satisfactory in report 50-361/84-32. Therefore, this item is considered close n. (Closed) Followup Item 50-361/83-18-01, Corrective Maintenance Order Inadequately describing work performed This item did not provide specific detail regarding the inadequacy but indicated that maintenance orders did not adequately describe the maintenance performed, the corrective action taken or the cause of the deficienc The licensee has since completely changed the methodology of initiating, tracking, and recording maintenance orders and result The current system is computerized and detailed. Current and ongoing inspections of maintenance operations have found documentation of maintenance work to be satisfactor Therefore, this item is considered closed, o. (Closed) Followup Item 50-361/83-28-01, Procedurt Changes concerning Limitorque liBC Series Gearheads This item's action was to ensure the licensee incorporated a licensee proposed change to procedure S023-I-6.23 in response to Limitorque problems identified in Information Notice 83-02 and a Part 21 repor The inspector verified the procedure change had been incorporate The current procedure number is S023-I-6.150. This item is considered close _ .

. (Closed) Followup item 50-361/83-32-01, Licensee's Ability to-Verify Compliance with Distribution Controls of Documents In this item the inspector had expressed concern that the extensive distribution of controlled documents by the document control staff could tax their ability from a staff size standpoint. Additionally, the' inspector noted that the licensee did not have a system of checks and balances to verify that changes entered by the document distribution staff had been accomplished accuratel The inspector examined the controls and changes implemented since the concerns were expresse The licensee's actions included audits and reductions in the amount of the distributions made.

'

The licensee took three major actions to ensure document distribution was performed accurately. First, extensive regular QA audits were performed over a sixteen-month period in different controlled document locations. The QA personnel tracked error rates 1

-

which were found to be initially high. As corrective measure were put in place the error rates were reduced significantly.

Secondly, the document distribution organization initiated self audits, which consist of a 100 percent check of each controlled document station on a regular basi Thirdly, the licensee has reduced the number of controlled stations from approximately 57 to 3 '

Based on the licensee's actions taken and the system in place to r check the accuracy of distribution control (through internal and external audit) this item is considered close .
