result of the inspection conducted by Messrs. R. E. Farrell and P. !

Michaud during the period of June 1 through July 15, 1989 (Reference '

!

Failure to Follow Procedure Criterion V of Appendix B to 10 CFR Part 50 and the liceosee's approved Quality Assurance Program require activities affecting quality to be accomplished in accordance with documented instructions, procedures, or drawing Procedure NPAP-19, Issue 1, " Radioactive Gaseous Effluent Releases,"

Attachment 19C, Step 1 states in part, prior to making a release, to

" Verify HS-6335 is positioned to Tank 1B."  ;

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 releas Connr?Aesa f f(:89#(d9 y) { W 1.L 't' sY' t - ff'

P-89343 i Page 2 l September 6, 1989 j Reason For The Violation If Admitted The violation is admitte 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 receive Specifically, valves V-6349 and V-63237 were opened instead of valves V-6350 and V-6323 In addition, the independent verification was performed concurrently )

with the valve lineup. The independent verifier did not identify j 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

'

waste receiver were immediately analyze 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 the limits allowed by the Technical Specification 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 inattention on the part of the Operators while performing a routine evolution. The error was compounded by a departure from station policy governing independent verification activitie The two Operators who performed and verified the valve lineup were disciplined in accordance with station disciplinary polic Attention to detail, management expectations, and the need to independently verify the performance of valve lineup evolutions have 1 been re-emphasize'd at Shift Supervisor staff meetings and Operations j Department meeting l Corrective Steps Which Will Be Taken to Avoid Further Violations No further actions are planne I l '!
