Nuclear Regulatory Commission November 13, 2007 – Federal Register Recent Federal Regulation Documents

Notice is hereby given that the staff of the Nuclear Regulatory Commission (NRC) has prepared a model safety evaluation (SE) relating to the revision of Standard Technical Specifications (STS), NUREG-1430 (B&W), NUREG-1431 (Westinghouse), NUREG-1432 (CE), NUREG- 1433 (BWR/4) and NUREG-1434 (BWR/6). Specifically the SE addresses: (1) The revision of the technical specification (TS) surveillance requirement (SR) 3.1.3.2 frequency in STS 3.1.3, ``Control Rod OPERABILITY,'' (NUREG-1433 and NUREG-1434), (2) a clarification to the requirement to fully insert all insertable control rods for the limiting condition for operation (LCO) in STS 3.3.1.2, Required Action E.2, ``Source Range Monitor Instrumentation'' (NUREG-1434 only), and (3) the revision of Example 1.4-3 in STS Section 1.4 ``Frequency'' to clarify the applicability of the 1.25 surveillance test interval extension (NUREG-1430 through NUREG-1434). The NRC staff has also prepared a model license amendment request and a model no significant hazards consideration (NSHC) determination relating to this matter. The purpose of these models is to permit the NRC to efficiently process amendments that propose to modify TS control rod SR testing frequency, clarify TS control insertion requirements, and clarify SR frequency discussions. Licensees of nuclear power reactors to which the models apply can request amendments, confirming the applicability of the SE and NSHC determination to their plant licensing basis.
