24-HOUR NRC 91-01 BULLETIN NOTIFICATION INVOLVING FAILURE TO MAINTAIN DOUBLE CONTINGENCY
"On 1/25/99 at 1430 CST, NCS [nuclear criticality safety] Incident report NCS-INC-99-001 was identified via ATR [problem report] as being incorrect. This NCS incident report was incorrectly classified on 1/12/99 and was subsequently not reported. The original NCS incident report concerned a pump subassembly which had been removed and the Post NDA [non-destructive assay] had not been performed within 24 hours as required by TSR 2.5.4.2. It incorrectly identified that this did not constitute a loss of a leg of the double contingency principle. Upon further review, NCS has determine that one of the legs of the double contingency principle is established by the independent verification of an always safe mass by post-removal NDA measurements performed within 24 hours of removal. Since this did not occur in the assumed time frame, double contingency was not maintained even though the NDA results did confirm an always safe mass.
"Ropes/posting used to isolate personnel from area implemented on 1/12/99 were removed that day when post-removal NDA results were obtained.
"This event is being categorized as a 24-hour event in accordance with Safety Analysis Report Table 6.9-1, Criteria A.4.a and NRC Bulletin 91-01 Supplement 1 report."
THE NRC RESIDENT INSPECTOR HAS BEEN INFORMED AND THE DOE SITE REPRESENTATIVE WILL BE INFORMED.
