| Title | Licensee-Identified Violation |
| Description | 10 CFR 50 Appendix B, Criterion III requires that measures shall be established to assure that applicable regulatory requirements and design basis are correctly translated into specifications, drawings, procedures, and instructions. These measures shall include provisions to assure that appropriate quality standards are specified and included in design documents and that deviations from such standards are controlled. Contrary to the above, the licensee discovered the Chemetronics Model 504 heat detectors (Firestats) installed in the common Farley DG Building are not installed as required per station drawing D-170336. Note 5 on this station design drawing required the detectors to be installed in close proximity to detectors which activate the buildings carbon dioxide fire suppression system. The Firestats are installed to control the closing of each individual room ventilation louvers and stop ceiling exhaust fans in those rooms, thus preserving the carbon dioxide fire extinguishing agent. The licensee determined the arrangement of detectors is outside the UL/FM listed spacing required for these detectors. The licensee evaluated the detectors in the other four DG rooms and discovered that three of the four rooms had improper spacing. The licensee has included this condition in their CR system as CR 2008102490. This finding is of very low safety significance because total estimated risk contribution for all fire scenarios was less than 1E-6. A regional Senior Reactor Analyst reviewed the Phase 2 SDP Screening of this performance deficiency and concurred that the matter was of very low safety significance (Green). In addition to reviewing the Phase 2 the analyst performed an independent review using Phase 3 methodology |
