An NRC-identified
NCV of the
Fire Protection Program (
FPP) required by
10 CFR 50.48 and License Condition 2.C.5, was identified for failing to adequately implement
transient combustible controls.
Transient combustible material stored adjacent to the B rod control motor generator (
MG) set and in front of a manual hose station was not in an established housekeeping area, and was not evaluated for acceptability by the site fire protection engineer (FPE) as required by the
FPP specified procedure, Nuclear System Directive NSD-313, Control of Combustible and Flammable Material. The failure to control
transient combustibles in the Unit 2 electrical
penetration room in accordance with NSD-313 was a performance deficiency. The performance deficiency was more than minor because if left uncorrected it could
lead to a more significant safety concern in that an electrical fault in the adjacent
MG set panel could ignite the combustibles which could
lead to a potential plant
transient. The finding was determined to be of very low safety significance (Green) as the combustibles did not meet the criteria requiring a phase 2 or 3 analysis as described in
IMC 0609, Appendix G, Attachment 1, Checklist 2. This finding had a cross cutting aspect in the Resources component of the area of Human Performance because the personnel involved were not adequately trained in the procedural requirements of NSD-313.
