Subject : Notification of Non-Compliance to TS 4.3.1 (License # R-126, Doc # 50-407)

Dear Sir:

i As required in Technical Specificatidns 6.10 (3) (a), we are informing you via this letter that as 1

of 12/27/93 we are not in compliance with technical specification 4.3.1. The specification states,
in part, that "the control rods shall be visually inspected for deterioration at intervals not to exceed 2 years" Our control rod was last inspected December 1991 during our scheduled biennial inspection.

The detailed visual shim and safety control rods inspections were completed on April 15,1991 as part of our console upgrade program. (We replaced our two remaining winch drives with rack-in-pennon drives.) The NEL staff used this detailed inspection (operator log 23 page 118, and NEL 002) to satisfy the biennial surveillance requirement. While it was convenient to do so, this i

action resulted in moving forward the required time to complete the next inspeedon for the safety and shim rods to April 1993. Unfortunately , the change went unnoticed by the current operating staff until preparation for the regularly scheduled control rod inspection in December 1993. We are, therefore,6 months delinquent in completing the inspection for these two control rods.

During the period between inspections, the control rods operated satisfactorily with no control rod or drive malfunction. All control rods underwent inspection December 29,1993. They i functioned properly with no noticeable wear or deterioration of material. Other daily, monthly, and semi-annual surveillance requirements assure safe and reliable operation of the control rods.

Personnel safety nor equipment performance was never in jeopardy.  ;

As Reactor Supervisor, I notified the chairman of the Reactor Safety Committee of our non- I compliance to this specification on December 30,1993. After correcting the discrepancy and l taking steps to prevent repetition of this infraction,I authorized that the reactor resume operation as of January 4,1994. If you have any questions or wish to discuss this matter further, please call me at (801) 581-8499.

i i Respec ,lly, .
