SUBJECT:
NRC INSPECTION REPORT 89-12 fiEFERENCE:
(1)
NRC Letter, Milhoan to Williams, dated August 8, 1989, (G-89257)
Dear Sirs:
This letter is in response to the Notice of Violation received as a result of the inspection conducted by Messrs. R. E. Farrell and P. W.
Michaud during the period of June 1 through July 15, 1989 (Reference 1). The following response to the item contained in the Notice of Violation is hereby submitted:
Failure to Follow Procedure Criterion V of Appendix B to 10 CFR Part 50 and the licensee's approved Quality Assurance Program require activities affecting quality to be accomplished i r.
accordance with documented instructions, procedures, or drawings.
Procedure NPAP-19 Issue 1, " Radioactive Gaseous Effluent Releases," 9C, Step 1 states in part, prior to making a release, to
" Verify HS-6335 is positioned to Tank 18."
Contrary to the above, on June 25, 1989, the failure to verify the positioning of HS-6335 to Tank 1B resulted in an unanalyzed gaseous waste release.

y P-89343 Page 2 September.6, 1989 Reason'For The Violation If Admitted The violation is admitted ~.
The violation was -due.to personnel error. Gas Waste release form' 1
- 2331' correctly specified that the *B" gas waste receiver was to be released,. but the valve lineup for the release was erroneously performed for the "A"
gas-waste receiver.
Specifically, valves V-6349 and V-63237 were opened instead of valves V-6350'and V-63235.
In addition, the independent verification was performed concurrently with the valve lineup. The. independent verifier did not identify the error. Later, the Reactor Operator observed that the pressure in the 'on-line gas waste receiver was dropping instead of the off-line
~
gas waste receiver. The release was remotely ' terminated and an Equipment Operator was instructed to check the valve lineup at which time the error was discovered. The remaining contents of "A"
gas wasteL receiver were. immediately analyzed.
The results of the analysis indicated that the total activity released during the twenty minutes was 2.51 E+4 microcuries. This value represents 0.85 percent of theilimits allowed by the Technical Specifications.
Corrective Steps Which Have Been Taken and The Results Achieved The procedure was reviewed for adequacy. No procedure deficiencies were found. The root cause for the. event was determined to be the part of the Operators while performing a routine inattention on evolution. The error was compounded by a departure from station policy governing independent verification activities.
The two Operators-who performed ar.d verified the valve lineup were disciplined in accordance with station disciplinary policy.
Attention to detail, management expectations, and the need to independently verify the performance of valve lineup evolutions have been-re-emphasized at Shift Supervisor staff meetings and Operations Department meetings.
l Corrective Steps Which Will Be Taken to Avoid Further Violations No further actions are planned.
