ENCLOSURE SUPPLEMENTAL RESPONSE TO J. P. O'REILLY'S LETTER DATED JANUARY 9, 1981, REGARDING BROWNS FERRY NUCLEAR ?LANT (50-259/80-40, 50-260/80-35, AND 50-296/80-34)
Infraction A As required by Technical Specification 3 10.A.1, refueling interlocks sha 1 be operable during refueling operation.
Contrary to the above, on October 5,1980, fuel was loaded into the core with a temporary alteration on control rod 54-19 which defeated the refueling interlocks for prevention of leading fuel with a control rod withdrawn.
This is an infraction applicable to unit 2.
Response
On October 5,1980, subsequent to maintenance on control cella 58-19 and 54-19, fuel was leaded into control cell 58-19 with control rod 54-19 withdrawn and the " full in" position interlock bypassed. There was no fuel in control cell 54-19 at the time of the occurrence; however, all refueling interlocks were not operable as required by Technical Specification 3.10.A.1.
Corrective Steps Taken and Results Achieved A.
Fuel handling was immediately stopped. Control rod 54-19 was inserted and the temporary alteration removed from the " full in" position interlock of control rod 54-19 3.
GOI 100-3 (Refueling operations) was revised to include a procedure for unloading cor. trol cells for control cell maintenance. Steps were included to ensure placement and removal of refueling interlock bypasses in accordance with Technical Specification 3 10.A.1, 3.10.A.5.a, and 3 10.A.6.a.
C.
A checklist was written and included in GOI 100-3 that ensures any temporary conditions are removed from the refueling interlocks and the interlocks verified in service each time fuel movement is stopped for an 8-hour period or greater.
I
1 o
e 2-Corrective Steps Taken to Avoid Further Noncompliance 1
In addition to 3 and C above, this incident will be reviewed by fuel-handling crews in refueling training classes before future refueling operations.
Date Full Compliance Achieved Full compliance was achieved on November 26, 1980, when revisions to GOI 100-3 were completed.
Infraction C Our original response to this infraction committed to procedure revision before the next refueling outage in April 1981.
As discussed with your staff, we amend this response to have the procedures revised before unit 1 core loading scheduled for July.
