| E6-22391 | Technical Specification Improvement to Remove the Main Steam and Main Feedwater Valve Isolation Time From Technical Specifications Using the Consolidated Line Item Improvement Process | Notice | Notice is hereby given that the staff of the Nuclear Regulatory Commission (NRC) has prepared a model Application related to changes to the Standard Technical Specifications (STS), Section 3.7.2, "Main Steam Isolation Valves (MSIVs)" and Section 3.7.3 "Main Feedwater Isolation Valves (MFIVs), Main Feedwater Regulation Valves (MFRVs), and [associated bypass valves]." The changes remove the specific isolation time for the isolation valves from the associated STS Surveillance Requirements (SRs). The bracketed isolation time in the STS SRs is replaced with the requirement to verify the valve isolation time is within limits. The specific isolation time required to meet the STS surveillances would be located outside of the technical specifications in a document subject to control by the 10 CFR 50.59 process. The NRC staff has also prepared a model safety evaluation (SE) and 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 adopt the associated changes into plant-specific technical specifications (TS). Licensees of nuclear power reactors to which the models apply may request amendments confirming the applicability of the SE and NSHC determination to their reactors. | 2006-12-29 | 2006 | 12 | https://www.federalregister.gov/documents/2006/12/29/E6-22391/technical-specification-improvement-to-remove-the-main-steam-and-main-feedwater-valve-isolation-time | https://www.govinfo.gov/content/pkg/FR-2006-12-29/pdf/E6-22391.pdf | Nuclear Regulatory Commission | 383 | Notice is hereby given that the staff of the Nuclear Regulatory Commission (NRC) has prepared a model Application related to changes to the Standard Technical Specifications (STS), Section 3.7.2, "Main Steam Isolation Valves (MSIVs)" and Section 3.7.3... |
