ABSTRACT:
At 1200 hours0.0139 days <br />0.333 hours <br />0.00198 weeks <br />4.566e-4 months <br />, on December 19, 1989, Unit One and Unit Two were in the RUN mode at 90 and 89 percent of rated core thermal power, respectively.
QAP 1100-7, Approval and Authorization of Temporary Procedures and Temporary Changes to Permanent Procedures, was found to be in violation of Technical Specification (TS) 6.2.C.1 for Temporary Procedure Changes involving a change in intent. QAP 1100-7 did not require signatures from both the Department Head and ;
Assistant Superintendent as stated in T.S. 6.2.C.I.
1 The cause of this event was management oversight in the preparation and review of a previous change to T.S. 6.2.C.1. The change mistakenly added the Assistant i Superintendent in the review process when the intent was only to replace the Department Head Review.
QAP 1100-7, T1, and T6 were revised to comply with T.S. 6.2.C.I. This Technical ,
Specification will be revised to match the intent of the previous change. Also, a '
procedure will be implemented to review procedures when a Technical Specification change is implemented.
This report is submitted to comply with the requirements of 10CFR50.73(a)(2)(1)(B). I i

PLANT AND SYSTEM IDENTIFICATION:
General Electric;- Boiling Water Reactor - 2511 MHt rated core thermal power.
EVENT IDENTIFICATION: Violation of Technical Specifications Concerning Review of-Te4crary Procedures Due to Management Oversight in the Preparation and Review of Technical Specification Change.
A.- CONDITIONS PRIOR TO EVENT:
Unit: One Event Date: December 19, 1989 Event Time:- -1200 Reactor Mode: 4 Mode Name: RUN Power Level: 90%
This-report'was initiated by Deviation Report D-4-1-89-123 RUN Mode (4) - In this position the reactor system pressure-is at or above 825 psig, and the reactor protection system is energized, with APRM protection and RBM interlocks in service (excluding the 15% high-flux scram).
B. DESCRIPTION OF EVENT:
At 1200 hours0.0139 days <br />0.333 hours <br />0.00198 weeks <br />4.566e-4 months <br />, on December 19, 1989, Unit One and Unit Two were in the RUN mode at 90 and 89 percent of rated core thermal power respectively.- QAP.Il00-7,~ Approval -
and Authorization of Temporary Procedures and-Temporary. Changes to Permanent Procedures, was determined to be in violation of Technical Specification 6.2.C.I.
This Technical Specification requires that procedures for:1tems-identified in Technical Specifications 6.2.A. and 6.2.B. and any changes to such procedures,shall be reviewed and approved by the Technical Staff Supervisor an Assistant-Superintendent or-the Technical Superintendent, and Department Head. responsible for the activity performed. At least one person approving each of the procedures shall hold a valid senior operator's license _(SRO). In addition, the procedures and changes thereto must have authorization by the Station Manager-before'being i implemented. '
For a Temporary Procedure' Change which alters the: intent of the original. procedure, QAP 1100-7 required the review of the Technical Staff Supervisor and; Department Head or an Assistant Superintendent. . This was not in accordance;with the Technical' Specification' which required both.the _ responsible Department Head and Assistant' Superintendent'or Technical Superintendent. The discrepancy was discov,ered by.a Corporate Office investigative team whlie examining the event" documented in Deviation: Report (DVR) 4-1-89-121, Unit One Turbine Trip Due to High:Rx Water Level-Signal.
Several immediate corrective actions were taken. All of the existing Temporary i Procedures which changed intent. -14 total, were reviewed and signed by the appropriate Department Head ^or Assistant Superintendent. QAP 1100-7, T1, and T6 were revised to comply with the Technical Specifications. Onsite Review (OSR)' 1 89-72 was performed to review the actions required due to the discrepancy between- 1 QAP 1100-7 and the Technical Specifications. These immediate corrective actions -j were all completed on December 19, 1989.,

There were no other structures, systems or components inoperable or degraded at=the start of this event which could have contributed to the event.
C.- ' APPARENT CAUSE OF EVENT:
This event is_being reported in accordance with4 10CFR50.73(a)(2)(1)(B), which requires the reporting of any operation or_ condition prohibited by the plant!s Technical Specifications.
The root cause of this event was management oversight in the development and OSR.
for a change to Technical Specification 6.2.C.1. The' 0SR (87-15) was performed on-June.5~, 1987. The intent of the change was to upgrade the level of procedure review by replacing'the. Department Head with the Assistant Superintendent in the
-review process. However, the Technical Specification change was mistakenly.
submitted with the Assistant _ Superintendent as an additional--reviewer and not a replacement to the Department Head review. When the change was approved and implemented, the existing procedure controlling temporary procedure changes no longer complied with Technical Specification.6.2.C.1. A contributing factor to the 4 event was that no review of existing procedures was made at-the time the Technical Specification was implemented.
D. -SAFETY ANALYSIS OF EVENT: ,
The safety consequences of this event are minimal. The only area of QAP'1100-7 that did not comply with the wording of Technical Specification 6.2.C._1 was the
. review of temporary procedure changes which alteredithe intent of;the original procedures. Although the procedure did not comply with the new Technical-1 Specification, the same technical level of on-site review was maintained, it was !
not enhanced to meet the new Technical Specification: change.' QAP 1100-7 did comply l
with Technical Specification 6.2.D for temporary procedure changes which did not alter the intent of the original procedure. Likewise, QAP 1100-4, Station !
Procedure Revisions, at all times complied with the Technical Specifications. -Th i s ' .I procedure covers permanent procedure changes and the addition of new' permanent procedures.
l E. CORRECTIVE ACTIONS: d Once the discrepancy between QAP 1100-7 and the Technical Specifications was discovered, all of the 14 existing Temporary Procedure changes which altered intent-were reviewed and signed.by the appropriate Department Head or Assistant Superintendent. QAP 1100-7, T1, and T6 were revised to comply with the Technical Specifications. Also, OSR 89-72 was performed to review the actions required due
~
to the discrepancy. These actions were completed on December 19, 1989.
A change to Technical Specificatioi. 6.2.C. will be submitted to reflect the intent of the original change (NTS 2542008912301). q i
To prevent the recurrence of this type of event, a procedure.will be-implemented that will require a review be performed of procedures whenever a new Technical 4 Specification change is implemented (NTS 2542008912302).
