d RESPONSE TO NOTICE OF VIOLATION Violation
{
10CFR50, Appendix B, Criterion V, " Instructions, Procedures, and Drawings," requires, in part, that activities affecting quality be prescribed by documented instructions and procedures of a type appropriate to the circumstances and be accomplished in accordance with these instructions or procedures.
Procedure SP2319, " Rod Position Verification," Revision 5, as revised by Temporary Memorandum TMA 1997-0122, required that the rod deviation monitor be declared inoperable if this monitor indicated that control rods were misaligned and the licensee determined that the rods were actually not misaligned and that the individual rod position indicators were operable.
Contrary to the above, the inspectors determined that on July 26,1997, SP2319, as revised by Temporary Memorandum TMA 1997-0122, was completed and the rod deviation monitor was not declared inoperable after the licensee determined that control rods were not actually misaligned and that the individual rod position indicators were operable following receipt of control rod indication deviation alarms.
This is a Severity Level IV violation (Supplement 1).
Response to Violation Reason for the Violation TMA 1997-0122 was issued to address recent concerns pertaining to the operability of the Individual Rod Position Indicators (IRPI) and the Rod Position Deviation Monitor (RPDM). Due to insufficient information in the Temporary Memorandum and insufficient training, TMA 1997-0122 was not adequately complied with in that the RPDM was not declared inoperable as required by SP2319.
Corrective Actions Taken Background information on operability determination for the IRPI and RPDM was sent to Shift Managers and Shift Supervisors.
PINGP 1224, ' Crew Meeting Review of Noteworthy Event /Near Miss/ Change," was issued to inform all operating crews of the Temporary Memo change to SP1319 and SP2319.
New Temporary Memos were issued to clarifiy the flow chart of SP1319 and SP2319 and to add words concerning RPDM operability.

v ge 2 e
A Request for Training, for Operations, on Tech Spec 3.10 has been issued.
The Administrative Work Instruction and associated form for Temporary Memorandums was revised to require the SRO approver to determine if training is needed for euch Temporary Memorandum.
Corrective Stoos That Will Be Taken to Avoid Further Violations:
Procedures SP1319[SP2319), ' Rod Position Verification," will be revised to include the required actions identified in the current Temporary Memorandums for determining IRPI and RPDM operability. Input from users of the procedures willbe factored into the revisions. The revisions will be completed by December 31,1997.
Equipment functionality and operability requirements for the IRPI and RPDM will be reviewed to determine if more appropriate requirements should be applied. A result of this review may be proposed changes to procedures, Technical Specifications, or the USAR.
The Administrative Work Instruction on ' Change Management' will be reviewed to determine if any changes are required based on the revision to the Temporary Memorandum process.
Calibration methods will be evaluated to determine if IRPI indications can be optimized in the 120 to 200 step range.
Physical modification of the IRPI circuitry is being considered to improve the linearity of the IRPl.
Date When Full Compliance Will Be Achieved Full compliance has been achieved.
