RESPONSE - NRC INSPECTION REPORT NOS.
50-259/82-48, 50-260/82-48, AND 50-296/82-48 D. M. VERRELLI'S LETTER TO H. G. PARRIS DATED FEBRUARY 9, 1983 (296/82-48-01)
Technical Specification 6.3.A.6 requires that detailed written procedures shall be prepared, approved and adhered to.
The daily surveillance log (S.I.2) defines the week, for surveillance purposes, as beginning on Sunday and ending on the following Saturday.
Contrary to the above, the requirement was not met on Unit 3 in that the required twice weekly cycling of the main steam isolation valves (MSIVs) wss accomplished only once, on December 21, 1982, for the week of December 19-25, 1982.
This is a Severity Level V violation (Supplement I).
1.
Admission or Denial of the Alleged Violation TVA admits the violation occurred as stated.
2.
Reasons for the Violation if Admitted The violation occurred due to personnel error in that the operator did not verify the work performed by the trainee to determine that SI requirements were met.
A contributing factor is that SI-2 is designed primarily for instrument checks, observations, and recordings; whereas the MSIV exercise requires valve manipulations.
There was no definitive schedule on the operator's Rolodex file used for routine scheduled items to ensure that the MSIV exercise was performed.
3 Corrective Steps Which Have Been Taken and the Results Achieved As noted in the inspection report, the surveillance was completed to verify operability.
In addition, the personnel involved have been reminded of the necessity for detailed review of SI-2, and a memorandum has been issued to all licensed personnel requiring that only licensed personnel can sign or initial where a operator's signature or initials are required.
l 4.
Corrective Steps Which Will Be Taken To Avoid Further Violations The operator's Rolodex file is being updated to include a distinct item for MSIV exercise requirements.
In addition, because of past problems with SI-2 end problems identified since this violation, TVA has taken the positive steps of assigning a Senior Management Representative and two experienced Senior Reactor Operators (Shift Engineers) the task of reviewing and revising SI-2, as necessary, to simplify and preclude future violations of this nature.
TVA believes that placing the emphasis on the operator's point-of-view is a key item that has been neglected during past revisions of SI-2.
5.
Date When Full Compliance Will Be Achieved Revisions to SI-2 will be oonpleted by April 29, 1983 s
