Followup of Previously Identified Items Test Briefing Following Shift Change - (81-10-06,. closed)_ ,

The " System Test Conduct" procedure has been revised to include briefinos of oncoming shifts following shift change . Preoperational Testing Flushing The flushing of systems reouired to support the primary system cold hydrostatic test, such as chemical volume control and shutdown cooling systems, as well as the hand cleaning of the reactor vessel and the hot and cold legs 'has been completed. The inspector obcerved portions of the hot and cold leg cleaning process.

-2-b. Certification of Test Personnel Selected records of certification of Bechtel prerequisite test personnel as well as their training records were inspecte The records appeared well managed and in_accordance witn administrative controls. While the records of the individuals that were reviewed were found to be consistent with project commitments to ANSI 45.2.6 (1978), APS has taken steps to transfer about 24 experienced APS/ contractor test engineers to .the prerequisite test organization to increase the startup experience

~

of prerequisite test engineer A review of selected APS test personnel certification records did not disclose deviations from commitments to its FSAR; however the management of the records warranted attention. APS is in the process of consolidating personnel records of its test engineers and upgrading the packages to reflect the revised administrative controls brought about by procedure changes and reorganizatio No items of noncompliance or deviations were noted, c. Preoperatinal Test Procedure Reviews The following procedures were reviewed for technical content and conformance with regulatory commitments, 'as well as for consistency with administrative controls governing procedure development, review and approval: High Pressure Safety Injection System Low Pressure Safety Injection System Safety Injection Tank System The insector'noted several instances where system components were not being tested to confirm FSAR descriptions of component performance. These omissions were known to APS test personnel and were to be included in revisions to procedures or included in other preoperational test procedure No items of noncompliance or deviation were note d. Preoperational Testing Documentation The inspector reviewed test documentation for the following preoperational tests which were in progress: RK01 - Plant Annunciation Sy tem CH03 - Volume Control Tank RJ01 - Plant Monitoring System

In each case administrative controls governing data taking, procedure revisions, test exceptions, test documentation packages and test logging were being accomplished in accordance .

with procedure No items of noncompliance or deviations were note _

_ Review of Prerequisite Testing Based on audits conducted by APS and Bechtel which disclosed problems with test documentation, it was determined that a complete review of completed prerequisite test documentation was warranted. This review, which was conducted by a special group of engineers representing APS, Bechtel and CE, concluded that the quality of some of the test information would not substantiate confirmation of proper component performance. As a result prequisite testing was suspended in the mechanical and electrical areas, and only limited testing is proceeding in the instrumentation and controls are Initial priority effort will be given to reviewing the electrical systems needed to support the primary system hydrostatic test, but efforts will eventually encompass all prerequisite testing performed to date. Test information is being reviewed and evaluated by special technical review teams. The effort is intended not ,

only to identify problems with test data so that corrective action can be taken on completed tests, but also to identify improvements in controls, procedures and test implementation for the balance of the Unit 1 and for the Units 2 and 3 testing program No items of noncompliance or deviations were note . Plant Tours Several tours of the plant were conducted during the period. Improved housekeeping efforts were noted with no observed instances of significant potential for equipment damage or fire initiation. Several maintenance activities in progress were .noted to have been properly authorize A review of Operations and Testing log books confirmed that major testing and operating activities were being documented. Shift and Testing supervision order and instruction logs were also being used and maintained. Water chemistry records indicated limits were being maintaine No items of noncompliance or deviations were noted.

_4_ ' Maintenance A review of selected _Bechtel and APS maintenance activities during the period included a review of preventive maintenance (PM) schedules, maintenance records'and observations of work. It was noted that PM schedules required by the prerequisite testing program were issued, and completed work was documented on the master schedule. The following selected maintenance activities were either observed directly or related

' documents were reviwed: volt DC battery PM Containment spray piping modification Repair of a leaking check valve downstream of the Volume Control Tank The following observations were made: Maintenance check sheets were being used and acceptance criteria were me . QC had returned to the Bechtel maintenance organization several maintenance documents for correction due to incompletenes . Work was properly authorize . Although retesting had been specified where necessary, it was difficult from available documentation to readily determine the results of the retest. APS recognized this short-coming and is modifying its work control procedur No items of noncompliance or deviations were note . Quality Assurance Several reports documenting QA findings were reviwed by the inspecto The findings were documented formally and problems which were not readily correctable were assigned to the responsible individuals for response and resolution. Report issuance and distribution were consistent with administrative control The inspector noted that during this period, the APS quality assurance organization was restructured. The new organization modifies the reporting structure so that all field and corporate QA units report to the corporate QA manager, who in turn reports to the Executive Vice President for Operations. This differs from the previous structure, where separate QA units reported to two different Vice President No items of noncompliance or deviations were note )

-5- Independent Inspection Effort During this inspection period the Train B LPSI pump tripped out on overcurrent when it inadvertantly started during an attempt to conduct a check of its control circuit breaker. While several factors contributed to the start of the pump, the principal cause is attributed to a lack of interface control - involving control cabinets under the jurisdiction of Bechtel construction and the APS startup organizatio Because the initiating circuit was housed in cabinets under the jurisdiction of both Bechtel and APS, proper circuit configuration was not maintained and the pump started when power was returned to the breaker. The LPSI system had been drained at the time. An evaluation of the matter by APS is in progress and will address corrective actions needed for future testin In addition, the applicant states that the pump bearing will be inspected

. and the pump mechanical prerequisite tests will be reru No items of noncompliance or deviations were note . Exit Meeting i An exit meeting was conducted with Mr. G. C. Andognini on May 26, 198 In addition to discussions on inspection findings, the need for APS to expedite the final planning related to document control was highlighte Mr. G. C. Andognini assured the inspector the matter was receiving priority attention.
