The following violations of very low safety significance (Green) were identified by the licensee and are violations of NRC requirements which meet the criteria of Section VI of the
NRC Enforcement Policy,
NUREG-1600, for being dispositioned as
NCVs. •
10 CFR 50, Appendix B, Criterion III, Design Control, requires that that measures shall be established to assure that applicable regulatory requirements and the design basis for structures, systems, and components are correctly translated into specifications, drawings, procedures, and instructions.
UFSAR Table 15.2-1 lists the
AFW pumps as being components that will not fail during a tornado since they are protected by tornado resistant structures. Contrary to this, turbine drive
AFW pumps 1/2-FW-P-2 were not completely protected in that the steam exhausts from the turbines could have been blocked by
tornado missile damage. This was identified in the licensees corrective action program as CR 001132. The inspectors assessed the finding using the
SDP and determined that the finding was of very low safety significance (Green) because it involved a severe weather initiating event and did not degrade more than one train of a multi-train safety system
