Dear Mr. O'Reilly:
Enclosed is our response to R.
C. Lewis'uly 6, 1979, letter, RII:CJ 50-259/79-16, 50-260/79-16, and 50-296/79-16, concerning activities at Browns Perry Nuclear Plant which appeared to be in noncompliance with NRC requirements.
We have reviewed the above inspection report and find no proprietary information in it.
Very truly yours, TENNESSEE VALLEY AUTHORITY

RESPONSE
TO NRC-OIE LETTER FROM R.
C.
LEWIS TO H. G. PARRIS DATED JULY 6, 1979, (REFERENCE RII:CJ 50-259/79-16, 50-260/79-16, AND 50-296/79-16)
Infraction Technical Specification 6.3.A. requires that detailed written procedures, including applicable check-off lists covering normal startup, operation, and shutdown of the reactor and all systems and components involving nuclear safety of the facility shall be prepared,
- approved, and adhered to.
Procedures BF 12.7 specifies that oncoming operating personnel will "acquaint themselves with plant conditions with special emphasis on abnormal or unusual conditions...and review journal entries back to'he person's last shift or back five days."
Oncoming personnel other than operations are required to "acquaint themselves with the plant status, acquaint themselves with abnormal or unusual conditions, and acquaint themselves with instruction from their supervisor or shift engineer."
Contrary to the above, this procedure was not adhered to in that on 5/29/79, the oncoming nuclear engineer supplied to operations for startup a rod with-drawal sequence that had been demonstrated to result in high control rod notch worths on 5/26 and 5/27/79, and that had been superseded by a rev'sed sequence on 5/27/79.
Additionally, the oncoming shift engineer put this sequence into use for reactor startup, and was apparently unaware of the short period events occurring on 5/26-27/79.
This had great potential for causing a repeat of the short period event and is an item of noncompliance.
~Res esse Corrective Ste s Taken and Results Achieved This event and the requirements of Standard Practice BF 12.7 have been discussed with the shift engineers involved.
In addition, the requirements of this standard practice are being discussed in supplemental training for operators and also in retraining for licensed operators.
Results section instruction letters (PPRS SIL-36 and -37) have been written to describe actions necessary for nuclear engineer shift turnover in accordance with Standard Practice BF 12.7,
0 0'
Corrective Ste s Which Will be Taken to Avoid Further Noncom liance For operations employees, requirements of Standard Practice BF 12.7 will be discussed in the retraining program for licensed operators.
For nuclear engineers, requirements of shift turnover will be discussed with those employees as part of an ongoing training program.
Date Full Com liance Achieved Concerning the shift engineers, full compliance was achieved June 1, 1979.
The supplemental training for operators will be completed by August 21, 1979.
Retraining for licensed operato'rs will be completed October',
1979.
The section instruction letters for nuclear engineers were completed on June 25, 1979.
