Sequoyah Nuclear Station Inspection Report Nos. 50-327/85-24 and 50-328/85-24

' NRC Region II has reviewed the licensee's response and concluded that there is sufficient justification for the violation. Specifically: The licensee states that on June 10 and 22,1985, ice removal from Unit 2 intermediate deck doors was verified, in part, by reviewing radiation work permits (RWP) and the documented performance of

,

Surveillance Instruction (SI)-3. To our knowledge, ice removal had not specifically been identified on a RWP. On June 10, 1985, a Maintenance Request (MR) A-553690 was generated to include the removal of the ice accumulation as documented in the Auxiliary Unit Operator Daily Journal. The actual performance of this maintenance request was at least six days later which would indicate that the ice remained on the ice condenser doors for that period of time. The staff recognizes that it was the licensee's practice to periodically remove ice from intermediate deck doors and that this action was accomplished informally under a general housekeeping RW The staff further recognizes that ice removal involves work on a safety-related system and, by the licensee's procedures, such work is required to be performed under a M Interviews conducted with licensee Auxiliary Unit Operators by NRC inspectors at the time of the inspection revealed that the meaning of the SI-3 acceptance criteria,

" free of frost accumulation," varied from operator to operato In fact, one operator stated that ice buildup on the doors was acceptable as long as the ice did not bridge the doors. The staff, therefore, does not have confidence that SI-3 was being performed adequatel The staff concludes that your response does not conclusively demonstrate that ice was removed from the Unit 2 intermediate deck doors within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> of being discovered or that the licensee took the necessary technical specification compensatory measures to monitor ice bed temperatures; therefore, the violation remains as writte ;
