Licensee action on revious ins ection findin s Closed Violation 388/84-34-01 Previous corrective actions werenot effective in preventing an operator from opening the incorrect knife switch on July 26, 1984.
The inspector reviewed the licensee response in PLA-2389 dated January 17, 1985.
The inspector verified the licensee corrective actions in the manner indicated below.
The inspector verified by review of WA-S42335 and WA-S42215 and inspection of selected 13.8 KV and 4160 V
ESS breaker cubicles that new labels have been installed on the breaker and bus DC control power switches.
Warning signs were installed on knife switches which disable the ESS bus and associated generator as an immedi-ate response to the event as described in inspection report 50-388/84-34 and were observed as still installed in this inspection.
The inspector's review of training records, lesson plan SY017 M-7 dated August 29, 1984 and interview with the training supervisor verified that training wa's pro-vided to the operators in breaker rackout procedures.
Operating Instruc-tion OI-AD-036, "Racking Breakers",
dated April 25, 1985 was reviewed.
The revised labeling for knife switches was included in this instructio Non routine training corrective actions were verified by review of OI-TR-004 "Non-Routine Training", revision 1 dated October 3, 1984,'eview of the shift non-routine training books for non-routine training irj process, and review of completed non-routine training.
By review of the shift non-routine training books, the inspector noted that training that was[required prior to assuming shift duties had been provided.
There was, however, an example of training that was required to be provided during the shift cycle that had not yet been provided to an individual of "B" shift in Mar'ch 1984 even though he participated in other shift training in April 1984.
I, This was brought to the licensee attention.
In addition, the inspector noted that the day shift operating crew on April 26, 1985 had outstandingl signa-tures in the training records of non-routine training to be provide'd during their current shift cycle.
During the inspection, the outstanding signa-tures were obtained prior to the completion of the shift cycle.
The in-spector identified these items and expressed concern at the exit meeting on the implementation of operating instruction OI-TR-004.
The licensee acknowledged the inspector's concern.
Training for event evaluators was provided by a three day course on event analysis by EGKG and a one week course provided by INPO on the Human Performance Evaluation System on sel,ected compliance group event evaluators.
Addit'ional training isI,planned.
The implementation of the Human Performance Evaluation System (HPES)
has been verified based on the review of AD-gA-121 "Human Performance Evalua-tion System",
Revision 0, dated March 5, 1985 and the review of "trial use" HPES Report 84-001.
Feedback on the report was provided by INPO on~~January 17, 1985 and February 6,
1985.
Based on the above review, the inspector verified the licensee's corrective actions and had no further questions.

The inspector reviewed the licensee'
scram recovery action item file 2-84-04-36.
The licensee evaluated the breaker response and concluded that breakers would not close on loss of DC control power due to no power to the 44 AX relay.
This is comparable to results de-scribed in inspection report 50-388/84-34.
Training on this item was provided to the operators in lesson plan SY017 M-7 dated August 29, 1984.
This item is close.0 Closed Violation 388/84-34-30 Independent verification activities did not prevent the wrong knife switch from being operated on July 26, 1984.
The inspector reviewed licensee response to the violation in PLA-2389 dated January 17, 1985.
The inspector reviewed Policy "Letter 6-84, Revision 0, dated October 9, 1984; Revision 1, dated January'~18, 1985; and d~aft Revision 2, dated April 25, 1985.
The revi sions reflect feedback experience from the work groups in the implementation of the station policy.
Verification activities are required for defined a'ctiv-ities with three types of verification established:
verification, ~inde-pendent verification and system test verification.
The inspector verified that Operations, Maintenance and Instrumentation and Control work groups have translated the station policies into procedures.
The inspector re-viewed the following documents and interviewed individuals from each group and verified the station policies have been translated into procedu'res:
AD-QA-300 "Conduct of Ope} ations",
Revision 5, dated February 22, 1985; OP-250-001
"RCIC System",
Revision 4, draft copy; AD-QA-500 "Conduct of Maintenance",
Revision 5, dated January 28, 1985; AD-QA-502 "Work Authorization System",
Revision 6, dated January 14, 1985; MI-PS-001 "
"Maintenance Work Planners Guide", Revision 8, dated November 16, 1984; WA-V41455 planning verification included; WA-S51030 completed verification activity; Instrument and Control Instruction IC-IS-01 "Control and Veri-fication of Operating Actions";
IBC correlation of new station policy on verification to IKC procedures not yet revised which is attached to~tall unchanged procedures; SI-161-301 draft copy of change to reflect new policy.
Based on review of the documents above and interviews, thei,sta-tion policy is being translated into procedures.
Feedback in the imple-mentation of the policy has resulted in revisions to the policy.
This is principally in feedback from 18C personnel in the verification of removal of equipment from service.
Independent verification is required when activities affect equipment from more than one division.
Independent verification requires the verifier not to accompany the individual per-forming the activity but must conduct his verification at a time after the activity is completed.
Based on the above, the inspector had no fur~'ther questions.
This item is closed.
