OPERATION APPLICABILITY APPLICABILITY SR 4.0.1 SRs shall be met during the specified conditions in the Applicability for individual LCOs, unless otherwise stated in the SR. Failure to meet a Surveillance, whether such failure is experienced during the performance of the Surveillance or between performances of the Surveillance, shall be failure to meet the LCO. Failure to perform a Surveillance within the specified frequency shall be failure to meet the LCO except as provided in SR 4.0.3.
Surveillances do not have to be performed on inoperable equipment or variables outside specified limits.
SR 4.0.2 Unless otherwise stated in these specifications, periodic surveillance tests, checks, calibrations, and examinations shall be performed within the specified surveillance intervals. These intervals may be adjusted plus 25%.
SR 4.0.3 If it is discovered that a surveillance was not performed within its specified frequency, declaring applicable Limiting Conditions for Operation (LCOs) not met may be delayed, from the time of discovery, up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or up to the limit of the specified frequency, whichever is greater. This delay period is permitted to allow performance of the surveillance. A risk evaluation shall be performed for any Surveillance delayed greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and the risk impact shall be managed.

VYNPS 3.0 LIMITING CONDITIONS FOR 4.0 SURVEILLANCE REQUIREMENT (SR)
OPERATION APPLICABILITY APPLICABILITY SR 4.0.3 (Continued)
If the surveillance is not performed within the delay period, applicable LCOs must immediately be declared not met, and applicable LCOs must be entered.
When the surveillance is performed within the delay period and the surveillance is not met (i.e., acceptance criteria are not satisfied),
applicable LCOs must immediately be declared not met, and applicable LCOs must be entered.
Amendment No. 263 3
VYNPS TS 4.0 Surveillance Requirement (SR) Applicability SR 4.0.l Bases SR 4.0.1 establishes the requirement that SRs must be met during the specified conditions in the Applicability for which the requirements of the LCO apply, unless otherwise specified in the individual SRs. This Specification is to ensure that Surveillances are performed to verify that variables are within specified limits. Failure to meet a Surveillance within the specified frequency, in accordance with SR 4.0.2, constitutes a failure to meet an LCO.
Unplanned events may satisfy the requirements (including applicable acceptance criteria) for a given SR. In this case, the unplanned event may be credited as fulfilling the performance of the SR.
SR 4.0.2 Bases SR 4.0.2 permits a 25% extension of the interval specified in the Frequency. This extension facilitates Surveillance scheduling and considers unit conditions that may not be suitable for conducting the Surveillance (e.g., transient conditions or other ongoing Surveillance or maintenance activities).
The 25% extension does not significantly degrade the reliability that results from performing the surveillance at its specified frequency. This is based on the recognition that the most probable result of any particular surveillance being performed is the verification of conformance with the SRs. The exceptions to SR 4.0.2 are those Surveillances for which the 25% extension of the interval specified in the frequency does not apply. These exceptions are stated in the individual Specifications.
The requirements of regulations take precedence over the TS.
The provisions of SR 4.0.2 are not intended to be used repeatedly merely as an operational convenience to extend surveillance intervals (other than those consistent with refueling intervals).
SR 4.0.3 Bases SR 4.0.3 establishes the flexibility to defer declaring an affected variable outside the specified limits when a surveillance has not been completed within the specified frequency. A delay period of up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or up to the limit of the specified frequency, whichever is greater, applies from the point in time that it is discovered that the surveillance has not been performed in accordance with SR 4.0.2, and not at the time that the specified Frequency was not met.
This delay period provides adequate time to complete surveillances that have been missed. This delay period permits the completion of a surveillance before complying with action statements or other remedial measures that might preclude completion of the Surveillance.
Amendment No. 263 4
VYNPS SR 4.0.3 Bases (Continued)
The basis for this delay period includes consideration of unit conditions, adequate planning, availability of personnel, the time required to perform the surveillance, the safety significance of the delay in completing the required surveillance, and the recognition that the most probable result of any particular surveillance being performed is the verification of conformance with the requirements.
Failure to comply with specified surveillance frequencies is expected to be an infrequent occurrence. Use of the delay period established by SR 4.0.3 is a flexibility which is not intended to be used as an operational convenience to extend surveillance intervals. While up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or the limit of the specified frequency is provided to perform the missed surveillance, it is expected that the missed surveillance will be performed at the first reasonable opportunity. The determination of the first reasonable opportunity should include consideration of the impact on plant risk (from delaying the surveillance as well as any plant configuration changes required to perform the surveillance) and impact on any analysis assumptions, in addition to unit conditions, planning, availability of personnel and the time required to perform the surveillance. This risk impact should be managed through the program in place to implement 10 CFR 50.65(a) (4) and its implementation guidance, NRC Regulatory Guide 1.182, "Assessing and Managing Risk Before Maintenance Activities at Nuclear Power Plants." This Regulatory Guide addresses consideration of temporary and aggregate risk impacts, determination of risk management action thresholds, and risk management action. The missed surveillance should be treated as an emergent condition as discussed in the Regulatory Guide. The risk evaluation may use quantitative, qualitative, or blended methods. The degree of depth and rigor of the evaluation should be commensurate with the importance of the component.
Missed surveillances for important components should be analyzed quantitatively. If the results of the risk evaluation determine the risk increase is significant, this evaluation should be used to determine the safest course of action. All missed surveillances will be placed in the licensee's Corrective Action Program.
If a surveillance is not completed within the allowed delay period, then the variable is considered outside the specified limits and the completion times of the Action Statements for the applicable LCO Conditions begin immediately upon expiration of the delay period. If a surveillance is failed within the delay period, then the variable is outside the specified limits and the completion times of the Action Statements for the applicable LCO Conditions begin immediately upon the failure of the surveillance.
Completion of the surveillance within the delay period allowed by this Specification, or within the completion time of the ACTIONS, restores compliance with SR 4.0.1.

By letter dated September 23, 2013 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML13273A204), Entergy Nuclear Operations, Inc. (ENO, the licensee),
submitted a notification to the U.S. Nuclear Regulatory Commission (NRC) indicating that it would permanently shut down Vermont Yankee Nuclear Power Station (VY) in the fourth calendar quarter of 2014. On December 29, 2014, ENO permanently ceased power operations at VY. On January 12, 2015, ENO certified that it had permanently defueled the VY reactor vessel (ADAMS Accession No. ML15013A426). Consequently, pursuant to Part 50 of Title 10 of the Code of Federal Regulations (10 CFR), paragraph 50.82(a)(2), the VY renewed facility operating license no longer authorizes operation of the reactor or emplacement or retention of fuel in the reactor vessel.
By letter dated March 28, 2014 (ADAMS Accession No. ML14091A291), as supplemented by letters dated April 24, June 9, June 11, and August 13, 2014; and May 4, 2015 (ADAMS Accession Nos. ML14119A101, ML14163A009, ML14168A282, ML14231A017, and ML15127A171, respectively), ENO requested an amendment to revise the VY renewed facility operating license and the associated technical specifications (TSs) to permanently defueled TSs consistent with the permanent cessation of reactor operation and permanent defueling of the reactor.
The supplemental letters dated April 24, June 9, June 11, August 13, 2014; and May 4, 2015, provided additional information that clarified the application, did not expand the scope of the application as originally noticed, and did not change the NRC staffs original proposed no significant hazards consideration determination as published in the Federal Register on February 17, 2015 (80 FR 8358).
Enclosure 2
2.0 REGULATORY EVALUATION
2.1 Technical Specifications Section 182a of the Atomic Energy Act requires applicants for nuclear power plant operating licenses to include TSs as part of the application. The NRC's regulatory requirements related to the content of!he TSs are contained in 10 CFR 50.36, "Technical specifications." Pursuant to 10 CFR 50.36, each operating license issued by the Commission includes TSs and includes items in the following categories: (1) safety limits (SLs), limiting safety systems settings and control settings, (2) limiting conditions for operation (LCOs), (3) surveillance requirements (SRs), (4) design features, (5) administrative controls, (6) decommissioning, (7) initial notification, and (8) written reports.
Section 50.36 of 10 CFR provides four criteria to define the scope of equipment and parameters to be included in the TS LCOs. These criteria were developed for licenses authorizing operation (i.e.,
operating reactors) and focused on instrumentation to detect degradation of the reactor coolant system (RCS) pressure boundary, process variables and equipment, design features, or operating restrictions that affect the integrity of fission product barriers during design-bases accidents (DBAs) or transients. A fourth criterion refers to the use of operating experience and probabilistic risk assessment to identify and include in the TSs those structures, systems, and components (SSCs) shown to be significant to public health and safety.
A general discussion of the criteria that were used by the NRC staff in its evaluation to ensure that TS LCOs proposed for deletion are no longer required to be included in TSs, is provided below.
Criterion 1 of 10 CFR 50.36(c)(2)(ii)(A) states that TS LCOs must be established for "installed instrumentation that is used to detect, and indicate in the control room, a significant abnormal degradation of the reactor coolant pressure boundary." Since no fuel is present in the reactor or RCS at the VY facility, this criterion is not applicable.
Criterion 2 of 10 CFR 50.36(c)(2)(ii)(B) states that TS LCOs must be established for a "process variable, design feature, or operating restriction that is an initial condition of a design basis accident or transient analysis that either assumes the failure of or presents a challenge to the integrity of a fission product barrier." The purpose of this criterion is to capture those process variables that have initial values assumed in the DBA and transient analyses, and which are monitored and controlled during power operation. The scope of DBAs applicable to a reactor permanently shutdown and defueled is reduced from those postulated for an operating reactor, and most TSs satisfying Criterion 2 are no longer applicable. One existing TS that defines the initial condition of the DBA associated with irradiated fuel movement is discussed in Section 3.5 of this safety evaluation (SE).
Criterion 3 of 10 CFR 50.36(c)(2)(ii)(C) states that TS LCOs for operation must be established for a SSC "that is part of the primary success path and which functions or actuates to mitigate a design basis accident or transient that either assumes the failure of or presents a challenge to the integrity of a fission product barrier." The intent of this criterion is to capture into TSs those SSCs that are part of the primary success path of a safety sequence analysis. Also captured by this criterion are those support and actuation systems that are necessary for items in the
primary success path to successfully function. The primary success path of a safety sequence analysis consists of the combination and sequences of equipment needed to operate (including consideration of the single failure criterion), so that the plant response to DBAs and transients limits the consequences of these events to within the appropriate acceptance criteria. There are no transients that continue to apply to permanently shutdown and defueled reactors. The scope of applicable DBAs that apply to VY is discussed in more detail in Section 3.0 of this SE.
Criterion 4 of 10 CFR 50.36(c)(2)(ii)(D) states that TS LCOs must be established for SSCs "which operating experience or probabilistic risk assessment has shown to be significant to public health and safety." The intent of this criterion is that risk insights and operating experience be factored into the establishment of TS LCOs. There are no longer any DBAs apply to permanently shutdown and defueled condition at VY that can result in a significant offsite radiological risk to public health and safety.
The NRC staff notes that in the course of this evaluation, information contained in NUREG-1625, "Proposed Standard Technical Specifications for Permanently Defueled Westinghouse Plants," Draft Report for Comment, March 1998 (ADAMS Accession No. ML082330233), was also considered. This draft NUREG provides examples of TSs that the staff found acceptable during previous TS reviews for permanently shutdown and defueled reactors.
2.2 Radiological Consequences Section 14 of the VY Updated Final Safety Analysis Report (UFSAR), "Station Safety Analysis" describes the OBA scenarios that are applicable to VY during power and refueling operations and the accidents with the greatest potential for radiation exposure. The most severe postulated accidents for nuclear power plants involve damage to the nuclear reactor core and the release of large quantities of fission products. When the reactor is permanently defueled and irradiated fuel assemblies are stored in the spent fuel pool (SFP) and the independent spent fuel storage installation (ISFSI), the spectrum of credible accidents is much smaller than for an operational plant, and most of the accident scenarios postulated in the UFSAR are no longer possible.
The licensee stated that the only accident with potential offsite radiological consequences that remains applicable to VY in the permanently shutdown and defueled condition is a fuel handling accident (FHA) in the reactor building where the SFP is located. The FHA analysis for VY shows that following 13 days of decay time after reactor shutdown, the dose consequences from an FHA are acceptable without certain systems operable during and following the event, provided that 20.67 feet of water is maintained above the irradiated fuel assemblies in the SFP.
The NRC staff evaluated the radiological consequences of the postulated FHA OBA against the dose criteria specified in 10 CFR 50.67, "Accident source term," and using the guidance described in NRC Regulatory Guide (RG) 1.183, "Alternative Radiological Source Terms for Evaluating Design Basis Accidents at Nuclear Power Reactors," July 2000 (ADAMS Accession No. ML003716792). RG 1.183 provides guidance to licensees on acceptable application of alternative source term (AST) submittals, including acceptable radiological analysis assumptions for use in conjunction with the accepted AST.
By letter dated March 29, 2005, the NRC approved the implementation of the AST methodology for FHA dose consequence analysis at VY by License Amendment No. 223 to Renewed Facility Operating License DPR-28 (ADAMS Accession No. ML041280490). The submittal also included changes to the VY TSs to reflect implementation of AST assumptions in accordance with 10 CFR 50.67.
The FHA-specific dose acceptance criteria are specified in NUREG-0800, "Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR [Light-Water Reactor] Edition," (SRP), Section 15.0.1, "Radiological Consequence Analyses Using Alternative Source Terms," Revision 0, July 2000 (ADAMS Accession No. ML003734190).
The dose acceptance criteria for the FHA are a total effective dose equivalent (TEDE) of 6.3 roentgen equivalent man (rem) at the exclusion area boundary (EAB) for the worst 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, 6.3 rem at the outer boundary of the low population zone (LPZ), and 5 rem in the control room (CR) for the duration of the accident.
3.0 TECHNICAL EVALUATION
3.1 Accident Analysis During normal power reactor operations, the forced inlet flow of water through the RCS removes the heat from the reactor by generating steam. The steam system, operating at high temperatures and pressures, transfers this heat to the turbine generator. The most severe postulated accidents for nuclear power plants involve damage to the nuclear reactor core and the release of large quantities of fission products to the RCS. Many of the accident scenarios postulated in the UFSAR involve failures or malfunctions of systems, which could affect the reactor core. With the termination of reactor operations at VY and the permanent removal of the fuel from the reactor core, most of the DBAs postulated in the UFSAR will no longer be possible.
The irradiated fuel will be stored in the SFP and the ISFSI. The reactor, RCS, steam system, and turbine generator are no longer in operation and have no function related to the storage of the irradiated fuel. Therefore, the postulated accidents involving failure or malfunction of the reactor, RCS, steam system, or turbine generator are no longer applicable.
Prior to permanently shutting down, Section 14 of the VY UFSAR described transients and DBAs that were applicable to VY during power operations. Since VY is permanently shut down and defueled, there are no longer any applicable transients. The only OBA that could potentially apply at this time to the permanently shutdown and defueled VY reactor would be the FHA.
3.2 Fuel Handling Accident Post-cessation of operations, an FHA onto the top of the core (or elsewhere within containment) is no longer possible and therefore, no longer part of the licensing basis. However, an FHA in the SFP (which is located in the reactor building) is still possible at VY, as long as spent fuel is stored in the SFP.
A revision to the FHA analysis was performed by the licensee to support the license amendment request "Eliminate Operability Requirements for Secondary Containment when Handling Sufficiently Decayed Irradiated Fuel or a Fuel Cask," dated November 14, 2013 (ADAMS Accession No. ML13323A516) to address the permanently defueled condition. The analysis
assumed a reasonable time post-cessation of operations for movement of fuel. The licensee then determined that if an FHA occurs, the dose consequences would be within 10 CFR 50.67 and RG 1.183 dose limits. The licensee evaluated the days of decay time after the reactor had been shut down in which the dose consequences were acceptable without relying on safety-related SSCs remaining operable for accident mitigation during and following the event. The licensee evaluated the maximum 2-hour TEDE to an individual located at the EAB, the 30-day TEDE to an individual at the outer boundary of the LPZ, and the CR The resulting doses were less than the RG 1.183 and SRP 15. 0.1 dose acceptance criteria, and the 10 CFR 50.67 limits.
The revised FHA analysis involves the inadvertent dropping of a fuel assembly during fuel handling operations, and the subsequent rupture of fuel rods in the dropped assembly, and/or the impacted assembly. The accident is assumed to involve the dropping of an assembly onto other assemblies, leading to the equivalent clad failure of the fuel rods. The fission product inventory in the fuel rod gap of the damaged rods is assumed to be released instantaneously into the fuel storage pool. The FHA dose analysis models 13 days of radioactive decay prior to the event. The NRC staff finds that the decay time assumed by the licensee is consistent with RG 1.183, Regulatory Position 3.1 and to be conservative because VY has been defueled since January 12, 2015, which is much greater than 13 days as of today. Based on the actual time to date for spent fuel decay, the iodine source terms would be negligible.
Fission products released from the damaged fuel are decontaminated by passage through the pool water, with the degree of decontamination dependent upon their physical and chemical form. The licensee assumed no decontamination for noble gases, a decontamination factor of 200 for radioiodine, and retention of all aerosol and particulate fission products. In ENO's response dated October 9, 2014, to the NRC staffs request for additional information (ADAMS Accession No. ML14288A317), ENO compared the decontamination factors and number of damaged assemblies for an FHA in the SFP to those for an FHA over the reactor core. ENO stated that the minimum amount of water needed above a postulated dropped and damaged assembly lying on top of a spent fuel rack is 20.67 feet rather than the 23 feet assumed for the FHA over the reactor core. ENO also stated that although the decontamination factor in the SPF is reduced (due to there being 20.67 feet of water above the postulated damaged fuel assembly), this reduction is more than offset by the smaller number of postulated damaged fuel rods in the SFP.
The fission product inventory in the fuel rod gap of the damaged rods is assumed to be released instantaneously from the fuel and the overlying fuel pool to the secondary containment building.
ENO's FHA with an open containment model no longer credits several safety systems after 13 days of fuel decay and is consistent with RG 1.183, Appendix B, and Regulatory Position 5.3. Entergy's FHA with an open containment model does not credit the secondary containment, standby gas treatment (SGT) system, or the reactor building ventilation.
Consistent with Regulatory Position 5.3, the radioactivity that escapes the fuel pool is released to the environment over a 2-hour time period. Therefore, ENO assumes the release to the environment is an unfiltered ground-level release via the reactor building blowout panels.
The NRC staff FHA analysis confirmed that the release point from the reactor building to the control room uses the most limiting combination of release and receptor locations. Since ENO is assuming a ground level release, the NRC staff finds it acceptable for the licensee to model
the FHA using the CR, EAB, and LPZ atmospheric dispersion factors for an FHA with a ground level release. These factors were previously approved in License Amendment No. 223.
The licensee's analysis of radiological consequences resulting from the postulated FHA for the permanently shutdown and defueled condition at VY concluded that the radiological consequences at the EAB, LPZ, and in the CR are within the dose criteria specified in 10 CFR 50.67 and accident-specific dose criteria described in SRP Section 15.0.1. The NRC staff has evaluated the licensee's analysis. In performing this evaluation, the NRC staff relied upon information provided by the licensee, as well as NRC staff experience in performing similar evaluations. The staff reviewed the methods, parameters, and assumptions that the licensee used in its radiological dose consequence analyses and finds that they are consistent with the conservative guidance provided in RG 1.183.
3.3 Proposed TS Changes 3.3.1 Section 1.0, "Definitions" The licensee proposed deleting the following definitions from TS 1.0 because they pertain to an operating reactor. Since VY is permanently shut down and defueled, the definitions no longer apply:
A. Reportable Occurrence - The equivalent of a reportable event which shall be any of the conditions specified in Section 50.73 to 10 CFR Part 50.
B. Alteration of the Reactor Core - The act of moving any component affecting reactivity within the reactor vessel in the region above the core support plate, below the upper grid and within the shroud.

- 1. Startup/Hot Standby Mode - In this mode the low turbine condenser vacuum trip is bypassed when condenser vacuum is less than 12 inches Hg and both turbine stop valves and bypass valves are closed; the low pressure and the 10 percent closure main steam line isolation valve closure trips are bypassed; the reactor protection system is energized with IRM neutron monitoring system trips and control rod withdrawal interlocks in service and APRM [average power range monitor] neutron monitoring system operable.
- 2. Run Mode - In this mode the reactor system pressure is equal to or greater than 800 psig [pounds per square inch gauge] and the reactor protection system is energized with APRM protection and RSM [rod-block monitor] interlocks in service.
S. Reactor Vessel Pressure - Unless otherwise indicated, reactor vessel pressures listed in the Technical Specifications are those measured by the reactor vessel steam space detector.
T. Refueling Outage - Refueling outage is the period of time between the shutdown of the unit prior to a refueling and the startup of the plant subsequent to that refueling. For the purpose of designating frequency of testing and surveillance, a refueling outage shall mean a regularly scheduled refueling outage; however, where such outages occur within 8 months of the completion of the previous refueling outage, the required surveillance testing need not be performed until the next regularly scheduled outage.
V. Shutdown - The reactor is in a shutdown condition when the reactor mode switch is in the shutdown mode position and no core alterations are being performed. When the mode switch is placed in the shutdown position a reactor scram is initiated, power to the control rod drives is removed, and the reactor protection system trip systems are de-energized.

The dose conversion factors used for this calculation shall be those listed in Federal Guidance Report (FGR) 11, "Limiting Values of Radionuclide Intake and Air Concentration and Dose Conversion Factors for Inhalation, Submersion, and Ingestion," 1988; FGR 12, "External Exposure to Radionuclides In Air, Water, and Soil," 1993; or NRC Regulatory Guide 1.109, Revision 1, October 1977.
NN. Core Operating Limits Report - The Core Operating Limits Report is the unit-specific document that provides core operating limits for the current operating reload cycle. These cycle-specific core operating limits shall be determined for each reload cycle in accordance with Specification 6.6.C.
Plant operation within these operating limits is addressed in individual specifications.
- 00. Reactor Protection System (RPS) Response Time - RPS Response Time shall be the time from the opening of the sensor contact up to and including the opening of the scram solenoid relay.
The NRC staff examined the TS definitions proposed for deletion and concludes that all the terms listed above are only meaningful to a reactor authorized to operate. Since VY is permanently shut down and defueled, the staff finds the deletion of these definitions from the TSs acceptable.
The licensee proposes to delete the following definitions from TS 1.0 because they are redundant to the information provided in TSs 4.0.1, 4.0.2, and 4.0.3.
Y. Surveillance Frequency - Relocated to Specifications 4.0.2 and 4.0.3.
Z. Surveillance Interval - Relocated to Specification 4.0.1.
The NRC staff examined the TS definitions "Surveillance Frequency" and "Surveillance Interval" proposed for deletion and concludes that these definitions are included in TSs 4.0.1, 4.0.2, and 4.0.3 and therefore, their deletion from the TSs are acceptable.
In addition, the licensee proposed adding a definition for "Certified Fuel Handler." The licensee proposes to define a certified fuel handler as:
A Certified Fuel Handler - A Certified Fuel Handler is an individual who complies with provisions of the Certified Fuel Handler training program.
TS 6.2.C.2 states "[a]n NRC approved training and retraining program for Certified Fuel Handlers shall be maintained." The NRC staff finds the definition of a Certified Fuel Handler conforms to the usage contained in the Administrative Controls section of the VY permanently defueled TSs and is consistent with the definition in 10 CFR Part 50, and is therefore, acceptable.
3.3.2 TS Sections 1/2.1 and 1/2.2 "Safety Limit" and "Limiting Safety System Setting" This section establishes Sls, which preclude violation of the fuel cladding integrity and RCS design pressure.
TS Sections 1.1 and 1.2, "Safety Limit" contains two separate specifications:
TS 1.1, "Fuel Cladding Integrity"
SLs for nuclear reactors are limits upon important process variables that are found to be necessary to reasonably protect the integrity of the certain physical barriers that guard against the uncontrolled release of radioactivity. The TS SL section also contains TSs 2.1 and 2.2, "Limiting Safety System Setting." Limiting safety system settings for nuclear reactors are settings for automatic protective devices related to those variables having significant safety functions. The restrictions promulgated in TSs 1.1 and 2.1 prevent overheating of the fuel and cladding, as well as possible cladding perforation that would result in the release of fission products to the reactor coolant. TSs 1.1 and 2.1 are applicable in Modes Run and Startup/Hot Standby. TSs 1.2 and 2.2 promulgate requirements on parameters to protect the integrity of the RCS against overpressure. TS 1.2 and 2.2 are applicable in all Modes.
The licensee proposes to delete the SLs and limiting safety system settings specified in TS Sections 1/2.1 and 1/2.2 because they are not applicable to a reactor that is permanently shut down and defueled. The licensee states that the SLs and limiting safety system settings TSs limit important process variables that are necessary to reasonably protect the integrity of certain physical barriers required for safe operation of the reactor in all Modes. However, 10 CFR 50.82(a)(2) prohibits operation of the reactor or placing fuel in the reactor vessel.
Therefore, the SL and limiting safety system settings TSs only address specific process variables that are no longer applicable to VY.
The NRC staff examined the SLs, limiting safety system settings and their Bases. There are two SLs in Section 1/2.1and1/2.2: "Fuel Cladding Integrity" and "Reactor Coolant System."
The fuel cladding integrity SL is set such that no significant fuel damage is calculated to occur if the limit is not violated. The RCS pressure limit is set such that the integrity of the RCS is not threatened due to an overpressure condition. As stated in the Bases, "the fuel cladding integrity SL is defined as the critical power ratio in the limiting fuel assembly, for which more than 99.9 percent of the fuel rods in the core are expected to avoid boiling transition, considering the power distribution within the core and all uncertainties." A limit is placed on the minimum critical power ratio. The Bases for the maximum RCS pressure state that "reactor coolant system
[integrity] is an important barrier in the prevention of an uncontrolled release of fission products."
Under the provisions of 10 CFR 50.82(a)(2), placing fuel in the reactor vessel and resuming power operations is no longer authorized by the 10 CFR Part 50 license when the licensee submits a certification to the Commission that power operations have been permanently ceased and that the fuel has been permanently removed from the reactor vessel. In this permanently defueled condition, there will be no minimum critical power ratio to be monitored and there will be no challenge to the RCS integrity. Based on these findings, the staff concludes that the SLs and limiting safety system settings no longer apply.
Based on the above, the NRC staff finds that the proposed deletions of TS Sections 1/2.1 and 1/2.2 are acceptable.
3.3.3 TS Section 3/4.0, "Limiting Conditions for Operations Applicability" and "Surveillance Requirement (SR) Applicability" This section contains the general requirements applicable to all LCOs and SRs and applies at all times unless otherwise stated in TSs.
LCO 3.0.8, "lnoperability of Snubbers," establishes conditions under which systems are considered to remain capable of performing their intended safety function when associated snubbers are not capable of providing their associated support function(s). The licensee proposes to delete LCO 3.0.8 in its entirety because all systems associated with snubbers are no longer required to be operable at VY given it is permanently shut down and in a defueled condition.
SR 4.0.1 establishes the requirement that SRs must be met during the modes or other specified conditions in the applicability for which the requirements of the LCO apply, unless otherwise specified in the individual SRs. This specification ensures that surveillances are performed to verify the operability of systems and components, and that variables are within specified limits.
The licensee proposes to revise this TS to delete the reference to "modes" since the reference to modes is no longer applicable to the VY reactor, which is permanently shut down and defueled.
SR 4.0.2 establishes the requirement that periodic surveillance tests, checks, calibrations, and examinations shall be performed within the specified surveillance intervals and allows an interval adjustment of 25 percent. In addition, it states that the operating cycle interval is considered to be 18 months. The licensee proposes to delete the sentence that discusses the operating cycle interval because the reference to operating cycle is no longer applicable when the reactor is permanently shut down and defueled at VY.
The NRC staff reviewed the proposed changes to the VY TSs concerning LCO and SR applicability. The staff concludes that the changes are consistent with the transition to a permanently shutdown and defueled facility. The provisions of 10 CFR 50.82(a)(2) prohibit a licensee of a permanently defueled facility from operating the plant or placing fuel in the reactor vessel. The proposed change to delete the references to "mode" is appropriate because the term refers to conditions of normal operation. Since the licensee will no longer be operating, reference to operating modes is no longer needed and the discussion of the operating cycle interval. Similar to modes, operating cycle interval no longer applies because the licensee will no longer be operating. Therefore, the changes appropriately reflect the change in plant status and are acceptable.
Because 10 CFR 50.82(a)(2) prohibits operation of the plant or placing fuel in the reactor vessel, all systems associated with snubbers are no longer required to be operable and are proposed for deletion from the TSs. As such, LCO 3.0.8 no longer applies to any systems remaining in the TSs. Therefore, the proposed deletion of LCO 3.0.8 is acceptable.
Based on the above, the staff finds that the proposed changes to LCO 3.0.8, SR 4.0.1, and SR 4.0.2 are acceptable.
3.3.4 TS Section 3/4.1, "Reactor Protection System (RPS)"
Section 3/4.1 of the VY TSs, "Reactor Protection System (RPS)," contains LCOs, actions, and SRs required for safe operation of the facility. The RPS initiates a reactor scram when one or more monitored parameters exceed their specified limits to preserve the integrity of the fuel cladding and the reactor coolant pressure boundary (RCPB) and minimizes the energy that must be absorbed following a loss-of-coolant accident (LOCA). The RPS TS applies to be
operable in Run, Startup/Hot Standby and Refuel with the reactor coolant temperature greater than 212 degrees Fahrenheit (F), and in Refuel with reactor coolant temperature less than 212 degrees F and any control rod withdrawn from a core cell containing one or more fuel assemblies. The licensee proposes to delete the RPS LCOs, since it is only applicable to an operating reactor and does not apply with the reactor permanently shut down and defueled at VY.
Based on its review of the proposed change, the staff concludes that TS Section 3/4.1 is only needed to provide the LCOs, actions, and SRs necessary to maintain the ability of the RPS to automatically initiate a reactor scram to preserve the integrity of the fuel cladding, preserve the integrity of the RCPB, and minimize the energy, which must be absorbed following a LOCA.
The RPS TS is only important for a reactor authorized to operate or retain irradiated fuel in the reactor vessel. However, because 10 CFR 50.82(a)(2) prohibits the licensee from operating the reactor or placing fuel in the reactor vessel at VY, there is no reactor core and the RPS system is no longer required.
The NRC staff also reviewed TS Section 3/4.1, which the licensee proposed for deletion to ensure that these LCOs are no longer satisfy the 10 CFR 50.36 criteria for inclusion in TSs, as described in Section 2.0 of this SE. The staff notes that this TS indicates MODES for which the TS is applicable. MODES, as defined in the TSs, is established by the mode-selector-switch.
The reference to MODES for a permanently shutdown and defueled reactor, such as VY, is no longer applicable and is no longer required. Because ENO has submitted certifications pursuant to 10 CFR 50.82(a)(2), it is prohibited from operating the reactor or placing fuel in the reactor vessel and VY is no longer in a configuration or a condition under which the TS MODES apply.
Based on the above, the staff finds that the proposed deletions of TS Section 3/4.1 are acceptable.
3.3.5 TS Section 3/4.2, "Protective Instrument Systems" Section 3/4.2 of the VY TSs, "Protective Instrument Systems," contains the LCOs, actions, and SRs that provide for appropriate functional capability of sensing and control instrumentation required for safe operation of the facility. This section contains the following LCOs:
Emergency Core Cooling System (ECCS)
Primary Containment Isolation Reactor Building Ventilation Isolation and Standby Gas Treatment System Initiation Control Rod Block Actuation
- Mechanical Vacuum Pump Isolation Instrumentation
- Post-Accident Monitoring Instrumentation
- Recirculation Pump Trip Instrumentation
- Degraded Grid Protective System
- Reactor Core Isolation Cooling (RCIC) System Actuation
The ECCS TS specifies the operability requirements for ECCS protective instrumentation. This TS requires the ECCS to be operable in Run, Startup/Hot Standby, Hot Shutdown, Refuel with the reactor coolant temperature greater than 212 degrees F, and in Refuel with reactor coolant steam pressure greater than 150 psig.
The primary containment isolation TS specifies the operability requirements for the primary containment isolation instrumentation, which automatically initiates closure of appropriate primary containment isolation valves (PCIVs). This is required to be operable in Run, Startup/Hot Standby, Hot Shutdown, Refuel with the reactor coolant temperature greater than 212 degrees F, and in Refuel with any turbine stop valve or turbine bypass valve not closed.
The reactor building ventilation isolation and SGT system initiation TS specifies the operability requirements for the reactor building ventilation isolation and SGT system initiation instrumentation. The instrumentation automatically initiates closure of the reactor building automatic ventilation system isolation valves and starts the SGT system following DBAs requiring isolation of secondary containment. This reactor building ventilation isolation and SGT system initiation are required to be operable in Run, Startup/Hot Standby, Hot Shutdown, Refuel with the reactor coolant temperature greater than 212 degrees F, during operations with the potential for draining the reactor vessel, during movement of irradiated fuel assemblies or fuel cask in secondary containment, and during alteration of the reactor core.
The control rod block actuation TS specifies the operability requirements for the control rod block instrumentation. This control rod block actuation is required to be operable when rated thermal power is greater than 30 percent.
The mechanical vacuum pump isolation instrumentation TS specifies the operability requirements for the mechanical vacuum pump isolation instrumentation. This instrumentation initiates an isolation of the mechanical vacuum pump following events in which main steam radiation monitors exceed a predetermined value. Tripping and isolating the mechanical vacuum pumps limits control room and offsite doses in the event of a control rod drop accident.
This mechanical vacuum pump isolation instrumentation is required to be operable in Run and Startup/Hot Standby when the mechanical vacuum pump is in service.
The post-accident monitoring instrumentation TS specifies the operability requirements for the post-accident monitoring instrumentation. The purpose of this instrumentation is to display in the control room, plant variables that provide information required by the control room operators during accident situations. This information provides the necessary support for the operator to take the manual actions for which no automatic control is provided and that are required for safety systems to accomplish their safety functions for DBAs. This post-accident monitoring instrumentation is required to be operable in Run and Startup/Hot Standby.
The recirculation pump trip (RPT) instrumentation TS specifies the operability requirements for the RPT instrumentation. The anticipated transient without scram (AlWS) prevention/mitigation system initiates a RPT, adding negative reactivity, following events in which a scram does not but should occur, to lessen the effects of an AlWS event. This RPT instrumentation is required to be operable in Run.
The degraded grid protective system TS specifies the operability requirements for the degraded grid protective system instrumentation. This instrumentation monitors the 4.16 kilovolt (kV) emergency buses. If the monitors determine that insufficient voltage is available and an ECCS initiation signal is present, the buses are disconnected from the offsite power sources and connected to the onsite emergency diesel generators (DG) power sources. This degraded grid protective system is required to be operable when the associated DG is required to be operable.
The RCIC system actuation TS specifies the operability requirements for the RCIC system instrumentation. This RCIC system actuation is required to be operable in Run, Startup/Hot Standby, Hot Shutdown, and in Refuel with reactor steam pressure greater than 150 psig.
The licensee proposes to delete all of the above TS LCOs, since they are only applicable to an operating reactor and do not apply to the permanently shutdown and defueled condition of VY.
The NRC staff reviewed the proposed change to the ECCS Instrumentation and concludes that this TS provides the LCO and SRs necessary to maintain the instrumentation associated with the ECCS systems that provide cooling to the reactor core. Specifically, these systems are the core spray (CS) system, low pressure coolant injection (LPCI) system, high pressure coolant injection (HPCI) system, and automatic depressurization system (ADS), which provide adequate emergency cooling capability to the reactor in the event of loss of cooling to the reactor core while operating the plant. However, 10 CFR 50.82(a)(2) prohibits the licensee from operating the plant or placing fuel in the reactor vessel. Therefore, the ECCS instrumentation, which only addresses ECCSs, is no longer required because the accidents these systems and components were designed to mitigate are no longer possible. Based on the above, the staff finds that the proposed deletion of the TSs related to ECCS instrumentation is acceptable.
The NRC staff reviewed the proposed changes to the primary containment isolation, reactor building ventilation isolation, and SGT system initiation instrumentation. The staff concludes that these TSs provide the LCOs and SRs necessary to maintain the instrumentation associated with the PCIVs, the reactor building ventilation isolation, and SGT initiation. The PCIV instrumentation automatically initiates closure of appropriate PCIVs. The reactor building ventilation isolation and SGT system initiation automatically initiates closure of the reactor building automatic ventilation system isolation valves and starts the SGT system following DBAs requiring isolation of secondary containment. This instrumentation limits fission product release during and following postulated DBAs. However, 10 CFR 50.82(a)(2) prohibits the licensee from operating the plant or placing fuel in the reactor vessel at VY. Therefore, the PCIV instrumentation, the reactor building ventilation isolation, and SGT system initiation instrumentation supports primary and secondary containment isolation, are no longer required.
Furthermore, the accidents these instruments were designed to contain are no longer possible.
Therefore, none of the instrumentation addressed by these TSs are needed by a reactor that has permanently shut down and defueled in accordance with 10 CFR 50.82(a)(2).
The NRC staff reviewed the proposed change to the control rod block actuation instrumentation.
The staff concludes that this TS provides the LCO and SRs necessary to maintain the instrumentation associated with control rod blocks. Control rods provide the primary means for control of reactivity changes. Control rod block instrumentation includes channel sensors, logic circuitry, switches, and relays that are designed to backup administrative controls on control rod movement. During shutdown conditions, control rod blocks from the Reactor Mode Switch-
Shutdown Position Function ensure that all control rods remain inserted to prevent inadvertent criticalities. However, because 10 CFR 50.82(a)(2) prohibits the licensee from operating the reactor or placing fuel in the reactor vessel at VY, there is no reactor core and the control rod block actuation instrumentation is no longer required.
The NRC staff reviewed the proposed change to the mechanical vacuum pump isolation instrumentation. The staff concludes that this TS provides the LCO and SRs necessary to maintain the instrumentation associated with the mechanical vacuum pump isolation. This instrumentation initiates an isolation of the mechanical vacuum pump following events in which main steam radiation monitors exceed a predetermined value. Tripping and isolating the mechanical vacuum pumps limits control room and offsite doses in the event of a control rod drop accident. The control rod drop accident instrumentation was designed to protect against control rod drop accident, is no longer possible because 10 CFR 50.82(a)(2) prohibits the licensee from operating the reactor or placing fuel in the reactor vessel at VY, there is no reactor core and the mechanical vacuum pump isolation instrumentation is no longer required.
The NRC staff reviewed the proposed change to the post-accident monitoring instrumentation.
The staff concludes that this TS provides the LCO and SRs necessary to ensure there is sufficient information available on selected unit parameters to monitor and assess unit status following an accident and allows operators to take manual actions specified in the emergency operating procedures. The purpose of this instrumentation is to display, in the control room, plant variables that provide information required by the control room operators during accident situations. This information provides the necessary support for the operator to take the manual actions for which no automatic control is provided and that are required for safety systems to accomplish their safety functions for DBAs. The DBAs that this instrumentation was designed to monitor are no longer possible because 10 CFR 50.82(a)(2) prohibits the licensee from operating the reactor or placing fuel in the reactor vessel at VY, there is no reactor core and the post-accident monitoring instrumentation is no longer required for plant safety.
The NRC staff reviewed the proposed change to the RPT instrumentation. The staff concludes that this TS provides the LCO and SRs necessary to maintain the instrumentation associated with the ATWS Prevention/Mitigation System. The ATWS Prevention/Mitigation System initiates a RPT, adding negative reactivity, following events in which a scram does not but should occur, to lessen the effects of an A TWS event. Tripping the recirculation pumps adds negative reactivity from the increase in steam voiding in the core area as core flow decreases. The A TWS event that this instrumentation was designed to protect against is no longer possible because 10 CFR 50.82(a)(2) prohibits the licensee from operating the reactor or placing fuel in the reactor vessel at VY, there is no reactor core and the RPT instrumentation is no longer required for plant safety.
The NRC staff reviewed the proposed change to the degraded grid protective system instrumentation. The staff concludes that this TS provides the LCO and SRs necessary to ensure the capability to detect a loss of offsite power and automatically actuate DGs to provide safety related power for SSCs needed for accident mitigation. The degraded grid protective system instrumentation monitors power available to the 4.16 kV emergency buses. Offsite power is the preferred source of power for the 4.16 kV emergency buses. If the degraded grid protective system instrumentation determines that insufficient voltage is available to the 4.16 kV emergency buses and an ECCS initiation signal is present, the buses are disconnected from the
offsite power sources and connected to the onsite DGs. The DBAs that this instrumentation was designed to mitigate are no longer possible because 10 CFR 50.82(a)(2) prohibits the licensee from operating the reactor or placing fuel in the reactor vessel at VY, there is no reactor core and the degraded grid protective system instrumentation is no longer required for plant safety.
The NRC staff reviewed the proposed change to the RCIC system actuation instrumentation.
The staff concludes that this TS provides the LCO and SRs necessary to maintain the instrumentation associated with RCIC. The purpose of the RCIC system instrumentation is to initiate action to ensure adequate core cooling when the reactor vessel is isolated from its primary heat sink (main condenser) and normal coolant makeup flow from the reactor feedwater system is insufficient or unavailable, such that RCIC System initiation occurs and maintains sufficient reactor water level such that initiation of the low pressure ECCS pumps does not occur. The DBAs that this instrumentation was designed to mitigate are no longer possible because 10 CFR 50.82(a)(2) prohibits the licensee from operating the reactor or placing fuel in the reactor vessel at VY, there is no reactor core and the RCIC system instrumentation is no longer required for plant safety.
The NRC staff also reviewed TS Section 3/4.2, "Protective Instrument Systems," which the licensee proposed for deletion to ensure that these LCOs no longer satisfy the 10 CFR 50.36 criteria for inclusion in TSs, as described in Section 2.0 of this SE. The staff notes that these TSs indicate MODES for which the TSs are applicable. MODE, as defined in the TSs, is established by the mode-selector-switch. The reference to MODES for a permanently shutdown and defueled reactor, such as VY, is no longer required. Because ENO has submitted certifications pursuant to 10 CFR 50.82(a)(2), it is prohibited from operating the reactor or placing fuel in the reactor vessel and VY is no longer in a configuration or a condition under which the TS MODES apply.
Based on the above, the staff finds that the proposed deletions of TS Section 3/4.2 are acceptable.
3.3.6 TS Section 3/4.3, "Control Rod System" Section 3/4.3 of the VY TSs, "Control Rod Systems," contains the LCOs, actions, and SRs that provide the ability of the control rods to control reactivity in the reactor and, in turn, protect the integrity of a fission product barrier. This section contains the following LCOs:
- Reactivity Limitations
- Scram Insertion Times
- Reactivity Anomalies
- Scram Discharge Volume Vent and Drain Valves The licensee proposes to delete all of the above TSs LCOs, since they are only applicable to an operating reactor and do not apply to the permanently shutdown and defueled condition of VY.
TS 3/4.3.A, "Reactivity Limitations," ensures that the core loading is limited to that which can be made subcritical in the most reactive condition during the operation cycle, with the highest worth operable control rod in its fully withdrawn position and all other operable rods inserted. This TS applies only when fuel is in the reactor vessel core.
TS 3/4.3.B, "Control Rods," establishes conditions to prevent the addition of excess reactivity due to improper operation of the control rods or failure of the control rod system. This TS applies in all modes unless specified.
TS 3/4.3.C, "Scram Insertion Times," establishes conditions to ensure that the control rods would insert to bring the reactor subcritical at a rate fast enough to prevent fuel damage during limiting power transients. These TSs apply when the reactor is in Run and Startup modes.
TS 3/4.3.D, "Control Rod Accumulators," establishes conditions to limit the number and location of control rod accumulators allowed to be inoperable to ensure that the control rods scram under varying reactor conditions that the reactor could be made subcritical. This TS applies when the reactor is in Run and Startup modes.
TS 3/4.3.E, "Reactivity Anomalies," establishes requirements to shut down the reactor if the difference between the actual critical rod configuration and the expected configuration during power operation exceeds 1 percent delta K per K. This TS applies when the reactor is in Run mode.
TS 3/4.3.F, "Scram Discharge Volume Vent and Drain Valves," ensures that sufficient volume is available at all times to allow a complete scram of all the control rods and thus bring the reactor subcritical. This TS applies when the reactor is in Run and Startup modes.
The NRC staff reviewed these proposed changes. The staff concludes that these TSs are only needed to provide the LCOs, actions, and SRs necessary to maintain reactivity parameters of the fuel loaded into a reactor vessel within the margins of conditions encountered during normal operation, anticipated occurrences, and for DBAs. The control rod system TSs are only important for a reactor authorized to operate or retain irradiated fuel in the reactor vessel.
However, because 10 CFR 50.82(a)(2) prohibits the licensee from operating the reactor or placing fuel in the reactor vessel at VY, there is no reactor core and the control rod systems are no longer required.
The NRC staff also reviewed TS Section 3/4.3, "Control Rod System," proposed for deletion to ensure that these LCOs no longer satisfy the 10 CFR 50.36 criteria for inclusion in TSs, as described in Section 2.0 of this SE. The staff notes that these TSs indicate MODES for which the TSs are applicable. MODE, as defined in the TSs, is established by the mode-selector-switch. The reference to MODES for a permanently shutdown and defueled reactor, such as VY, is no longer required. Because ENO has submitted certifications pursuant to 10 CFR 50.82(a)(2), it is prohibited from operating the reactor or placing fuel in the reactor vessel and VY is no longer in a configuration or a condition under which the TS MODES apply.
Based on the above, the staff finds that the proposed deletions of TS Section 3/4.3 are acceptable.
3.3.7 TS Section 3/4.4, "Reactor Standby Liquid Control System" Section 3/4.4 of the VY TSs, "Reactor Standby Liquid Control System," contains the LCOs, actions, and SRs that provide assurance of availability and operability of the standby liquid control system as a means of providing an independent reactivity control mechanism. This section contains the following LCOs:
- Normal Operation
- Operation with Inoperable Components
- Standby Liquid Control System Tank - Borated Solution The design objective of the Reactor Standby Liquid Control System is to provide the capability of bringing the reactor from full power to a cold, xenon-free shutdown assuming that none of the withdrawn control rods can be inserted. These TSs are required when the reactor is in Run and Startup/Hot Standby modes.
The reactor standby liquid control system TSs provide the requirements needed to meet the design objective and the requirements of the ATWS rule, 10 CFR 50.62, "Requirements for reduction of risk from anticipated transients without scram (ATWS) events for light-water-cooled nuclear power plants." The licensee proposes to delete all of the above LCOs, since they are only applicable to an operating reactor and do not apply to the permanently shutdown and defueled condition of VY.
The NRC staff reviewed the proposed change and concludes that because (1) 10 CFR 50.62 does not apply to nuclear power reactor facilities for which the certifications required under 10 CFR 50.82(a)(1) have been submitted and (2) 10 CFR 50.82(a)(2) prohibits the licensee from operating the reactor or placing fuel in the reactor vessel at VY, there is no reactor core and the reactor standby liquid control system is no longer required. The reactor standby liquid control system TSs are only applicable to a reactor authorized to operate or retain irradiated fuel in the reactor vessel.
The NRC staff also reviewed the Section 3/4.4, "Reactor Standby Liquid Control System," TSs proposed for deletion to ensure that these LCOs no longer satisfy the 10 CFR 50.36 criteria for inclusion in TSs, as described in Section 2.0 of this SE. The staff notes that these TSs indicate MODES for which the TSs are applicable. MODE, as defined in TSs, is established by the mode-selector-switch. The reference to MODES for a permanently shutdown and defueled reactor, such as VY, is no longer applicable and is no longer required. Because ENO has submitted certifications pursuant to 10 CFR 50.82(a)(2), it is prohibited from operating the reactor or placing fuel in the reactor vessel and VY is no longer in a configuration or a condition under which the TS MODES apply. Based on the above, the deletion of the Section 3/4.4, "Reactor Standby Liquid Control System" TSs are acceptable.
3.3.8 Section 3/4.5, "Core and Containment Cooling Systems" Section 3/4.5 of the VY TSs, "Core and Containment Cooling Systems," contains the LCOs, actions, and SRs that provide assurance of adequate cooling capability for heat removal in the event of a LOCA or isolation from the normal reactor heat sink, the main condenser. This section contains the following LCOs:
- Containment Spray Cooling Capability
- Residual Heat Removal (RHR) Service Water System
- Station Service Water and Alternate Cooling Tower Systems
- High Pressure Cooling Injection (HPCI) System
- Reactor Core Isolation Cooling System (RCIC)
- Minimum Core and Containment Cooling System Availability
- Maintenance of Filled Discharge Pipe The licensee proposes to delete all of the above TSs LCOs since they are only applicable to an operating reactor and do not apply to the permanently shutdown and defueled condition of VY.
TS 3/4.5.A, "Core Spray and Low Pressure Coolant Injection," provides sufficient cooling to the core to dissipate the energy associated with a LOCA. This TS applies whenever irradiated fuel is in the reactor vessel and prior to a reactor startup from a cold shutdown condition.
TS 3/4.5.B, "Containment Spray Cooling Capability," and TS 3/4.5.C, "Residual Heat Removal (RHR) Service Water System," ensure the ability to remove heat energy from the containment in the event of a LOCA. These TSs require both containment cooling spray loops be operable when the reactor water temperature is greater than 212 degrees F.
TS 3/4.5.C, ensures the ability to remove heat energy from the containment in the event of a LOCA. This TS applies whenever irradiated fuel is in the reactor vessel and prior to a reactor startup from a cold shutdown condition.
TS 3/4.5.D, "Station Service Water and Alternate Cooling Tower System." The station service water system essential equipment cooling loops provide redundant heat sinks to dissipate residual heat in the reactor fuel after a shutdown or accident. The alternate cooling tower system provides the necessary heat sink for normal post-shutdown conditions in the event that the station service water system becomes incapacitated. This TS applies whenever irradiated fuel is in the reactor vessel and the reactor coolant temperature is greater than 212 degrees F.
TS 3/4.5.E, "High Pressure Cooling Injection (HPCI) System," provides adequate cooling to the core for all pipe breaks smaller than those for which the LPCI or CS subsystems can protect the core. This TS applies whenever irradiated fuel is in the reactor vessel and the reactor steam pressure is greater than 150 psig.
TS 3/4.5.F, "Automatic Depressurization System," is designed to provide depressurization of the RCS during a small break LOCA if HPCI fails or is unable to maintain sufficient reactor water level. This TS applies whenever irradiated fuel is in the reactor vessel and the reactor steam pressure is greater than 150 psig.
TS 3/4.5.G, "Reactor Core Isolation Cooling System (RCIC)," is provided to maintain the water inventory of the reactor vessel in the event of a main steam line isolation and complete loss of outside power without the use of the ECCS. This TS applies whenever irradiated fuel is in the reactor vessel and the reactor steam pressure is greater than 150 psig.
TS 3/4.5.H, "Minimum Core and Containment Cooling System Availability," provides a method of transferring the residual heat from the reactor vessel following a shutdown or accident to a heat sink. This TS applies when irradiated fuel is in the reactor vessel and the reactor is in either a refueling of cold shutdown condition.
TS 3/4.5.1, "Maintenance of Filled Discharge Pipe," requires maintaining the discharge lines of the CS subsystems, LPCI subsystems, HPCI system, and RCIC system full of water to preclude the possibility of damage to the discharge piping due to water hammer action upon a pump start. This TS applies whenever the CS subsystems, LPCI subsystem, HPCI or RCIC are required to be operable.
The NRC staff reviewed the proposed changes to the core and containment cooling systems' TSs and has determined that these TSs are only needed to provide the LCOs, actions, and SRs necessary to maintain functionality of the systems that provide cooling to the reactor core in the event of a LOCA or isolation from the normal reactor heat sink. Under the provisions of 10 CFR 50.82(a)(2), placing fuel in the reactor vessel and resuming power operations are no longer authorized by the 10 CFR Part 50 license when the licensee submits a certification to the Commission that power operations have been permanently ceased and that the fuel has been permanently removed from the reactor vessel. In this condition, a LOCA will no longer be possible. Based on this, the staff concludes the core and containment cooling systems are no longer required at VY.
The NRC staff also reviewed TS Section 3/4.5, "Core And Containment Cooling Systems,"
which the licensee proposed for deletion, to ensure that these LCOs no longer satisfy the 10 CFR 50.36 criteria for inclusion in TSs, as described in Section 2.0 of this SE. The staff notes that these TSs indicate MODES for which the TSs are applicable. MODE, as defined in TSs, is established by the mode-selector-switch. The reference to MODES for a permanently shutdown and defueled reactor, such as VY, is no longer applicable and is no longer required.
Because ENO has submitted certifications pursuant to 10 CFR 50.82(a)(2), it is prohibited from operating the reactor or placing fuel in the reactor vessel and VY is no longer in a configuration or a condition under which the TS MODES apply.
The regulation in 10 CFR 50.46(a)(1 )(i) requires each boiling light-water nuclear power reactor fueled with uranium oxide pellets within cylindrical zircaloy or ZIRLO cladding must be provided with an ECCS designed to meet the cooling performance criteria following postulated LOCAs.
Thus, 10 CFR 50.46 does not apply to nuclear power reactor facilities for which the certifications required under 10 CFR 50.82(a)(1) have been submitted.
Based on the above, the NRC staff finds that the proposed deletions of TS Section 3/4.5 are acceptable.
3.3.9 Section 3/4.6, "Reactor Coolant System" Section 3/4.6 of the VY TSs, "Reactor Coolant System," contains the LCOs, actions, and SRs that provide assurance of the integrity and safe operation of the RCS. This section contains the following LCOs:
- Pressure and Temperature Limitations
- Coolant Chemistry
- Coolant Leakage
- Safety and Relief Valves
- Structural Integrity and Operability Testing
- Jet Pumps
- Single Loop Operation
- Recirculation System
- Thermal Hydraulic Stability The licensee proposes to delete all of the above TS LCOs, since they are only applicable to an operating reactor and do not apply to the permanently shutdown and defueled condition of VY.
TS 3/4.6.A, "Pressure and Temperature Limitations," specifies the maximum specified heatup and cooldown rates during reactor startup and shutdown to be consistent with the design assumptions and satisfy the stress limits for cyclic operation. This TS applies in all modes of normal operation.
TS 3/4.6.B, "Coolant Chemistry," specifies the radiochemistry limits for the reactor coolant in the RCS, which limit potential offsite doses due to postulated events. This TS applies for reactor power operation.
TS 3/4.6.C, "Coolant Leakage," specifies the maximum leakage rates of reactor coolant from the RCS, which allows prompt identification and isolation of leaks before the integrity of the RCS pressure boundary is impaired. This TS applies any time irradiated fuel is in the reactor vessel and the reactor coolant temperature is greater than 212 degrees F.
TS 3/4.6.D, "Safety and Relief Valves," specifies the requirements for the safety and relief valves, which are designed to prevent overpressurization of, and damage to, the RCS boundary.
This TS applies during reactor power operation and whenever the reactor coolant pressure is greater than 150 psig and the reactor coolant temperature is greater than 350 degrees F.
TS 3/4.6.E. "Structural Integrity and Operability Testing," specifies the requirements for structural integrity and operability testing of safety related components, which addresses the inservice inspection requirements of the RCS boundary components. This TS applies in all modes of normal operation.
TS 3/4.6.F, "Jet Pumps," specifies the requirements for the jet pumps. The jet pumps function as part of the reactor recirculation system to provide sufficient coolant circulation through the core during normal power operation to maintain normal operating temperatures. This TS applies when the reactor is in Run and Startup/Hot Standby modes.
TS 3/4.6.G, "Single Loop Operation," specifies the system settings and configuration necessary to operate the reactor with one recirculation loop, which prevents a cold water injection transient caused by an inadvertent pump start. This TS applies when the reactor is in Run and Startup/Hot Standby modes.
TS 3/4.6.H, "Recirculation System," specifies the requirements to shutdown the reactor when the recirculation system is not in operation. The reactor recirculation system consists of the two recirculation pump loops external to the reactor vessel, which provide the driving flow of water to the reactor vessel jet pumps. The reactor recirculation system provides sufficient subcooled water to the core during normal power operation to maintain normal operating temperatures.
This TS applies in all modes of normal operation.
TS 3/4.6.J, "Thermal Hydraulic Stability," specifies restrictions against operating the reactor in the power flow exclusion area. Reactor coolant flow instabilities are likely if the reactor is operated in the power flow exclusion area, and if not prevented or suppressed, can cause exceeding the specified fuel design limits. This TS applies when the reactor is in Run mode.
The NRC staff reviewed these proposed changes and concludes that these TSs provide the LCOs and SRs necessary to maintain the integrity of the RCS pressure boundary. All of these TSs are related to assuring the integrity of the RCS pressure boundary. Under the provisions of 10 CFR 50.82(a)(2), placing fuel in the reactor vessel and resuming power operations are no longer authorized by the 10 CFR Part 50 license when the licensee submits a certification to the Commission that power operations have been permanently ceased and that the fuel has been permanently removed from the reactor vessel. Therefore, the TSs contained in Section 3/4.6, which only address the RCPB, are no longer applicable.
The NRC staff also reviewed Section 3/4.6, "Reactor Coolant System," which the licensee proposed for deletion to ensure that these LCOs no longer satisfy the 10 CFR 50.36 criteria for inclusion in the TSs, as described in Section 2.0 of this SE. The staff notes that these TSs indicate MODES for which the TSs are applicable. MODE, as defined in TSs, is established by the mode-selector-switch. The reference to MODES for a permanently shutdown and defueled reactor, such as VY, is no longer applicable and is no longer required. Because ENO previously submitted certifications pursuant to 10 CFR 50.82(a)(2), it is prohibited from operating the reactor or placing fuel in the reactor vessel and VY is no longer in a configuration or a condition under which the TS MODES apply.
Based on the above, the staff finds that the proposed deletions of TS Section 3/4.6 are acceptable.
3.3.1 O Section 3/4. 7, "Station Containment Systems" Section 3/4.7 of the VY TSs, "Station Containment Systems," contains the LCOs, actions, and SRs that assure the integrity of the primary and secondary containment systems. This section contains the following LCOs:
- Secondary Containment System
- Primary Containment Isolation Valves
- Reactor Building Automatic Ventilation System Isolation Valves (RBAVSIVs)
The licensee proposes to delete all of the above TSs LCOs since they are only applicable to an operating reactor and do not apply to the permanently shutdown and defueled condition of VY.
TS 3/4.7.A, "Primary Containment," specifies the operability requirements for primary containment. The primary containment consists of a drywell, which encloses the reactor vessel and recirculation system, a pressure suppression chamber, which stores a large volume of water, a connecting vent system between the drywell and the suppression chamber, isolation valves, containment cooling systems, and other service equipment. The safety objective of the primary containment system in conjunction with the core standby cooling systems is to provide the capability, in the event of a postulated LOCA, to limit the release of fission products to the plant environment so that offsite doses remain well below the values specified in 10 CFR 50.67.
These TSs are required when the reactor is critical or when the reactor water temperature is above 212 degrees F and fuel is in the reactor vessel.
TS 3/4.7.B, "Standby Gas Treatment System," specifies the operability requirements for the Standby Gas Treatment (SGT) system. The SGT system is provided to limit airborne fission product release to the environment by the use of high efficiency filters and by the maintenance of a negative pressure in the reactor building. This TS applies whenever the reactor is in Run and Startup/Hot Standby modes.
TS 3/4.7.C, "Secondary Containment System," specifies the operability requirements for secondary containment. The secondary containment system consists of the reactor building, the SGT system, the reactor building normal heating ventilating and air conditioning system, and the reactor building penetrations. The secondary containment is designed to minimize the ground level release of airborne radioactive material and to control this release should an accident occur. This TS applies whenever the reactor is in Run and Startup/Hot Standby modes, during movement of irradiated fuel assemblies or the fuel cask in secondary containment, during alteration of the reactor core, or during operation with the potential for draining the reactor vessel.
TS 3/4.7.D, "Primary Containment Isolation Valves," specifies the operability requirements for PCIV. The primary containment design includes lines that penetrate the primary containment with different containment isolation valve configurations including double and single valve isolation. Automatic initiation is required to minimize the potential leakage paths from the containment in the event of a LOCA. This TS applies when the reactor is in Run mode.
TS 3/4.7.E, "Reactor Building Automatic Ventilation System Isolation Valves (RBAVSIV),"
specifies the operability requirements for the RBAVSIVs when secondary containment integrity is required. The function of the RBAVSIVs, in combination with other accident mitigation systems, is to limit fission product release during and following postulated DBAs. This TS applies whenever the reactor is in Run and Startup/Hot Standby modes, during movement of irradiated fuel assemblies or the fuel cask in secondary containment, during alteration of the reactor core, or during operation with the potential for draining the reactor vessel.
The NRC staff reviewed the proposed changes and concludes that these TSs provide the LCOs and SRs necessary to maintain the integrity of the primary and secondary containment systems.
Under the provisions of 10 CFR 50.82(a)(2), placing fuel in the reactor vessel and resuming power operations are no longer authorized by the 10 CFR Part 50 license when the licensee
submits a certification to the Commission that power operations have been permanently ceased and that the fuel has been permanently removed from the reactor vessel. In this condition, the operational conditions, transients, and accidents the containment SSCs were designed to contain are no longer possible, and there will be no challenge to containment integrity. The only OBA that could potentially apply at this time to the permanently shutdown and defueled VY reactor would be the FHA.
The licensee proposed a revision to the FHA in an application dated November 14, 2013 (ADAMS Accession No. ML13323A518), "Eliminate Operability Requirements for Secondary Containment When Handling Sufficiently Decayed Irradiated Fuel or Fuel Cask." The FHA analysis does not rely on primary containment or the primary containment isolation valves to mitigate the consequences of an FHA and after 13 days of fuel decay, secondary containment, RBAVSIVs, and SGT are no longer required to mitigate the consequences of the FHA. In November 14, 2013, application, the licensee stated that the changes proposed by this amendment would not be effective until 13 days after final reactor shutdown to allow for sufficient decay of the reactor fuel such that the fuel will no longer be considered recently irradiated, as defined in the FHA. The NRC staff's confirmatory analyses of VY's revised FHA yields results of the EAB, LPZ and CR doses that are less than the RG 1.183 and SRP 15.0.1 dose acceptance criteria.
Therefore, the TSs contained in Section 3/4.7, which address primary and secondary containment integrity, isolation, and leakage are no longer applicable following 13 days of fuel decay time after reactor shutdown. Furthermore, the accidents these systems and components were designed to contain are no longer possible, with the exception of the FHA. In the case of the FHA, the licensee stated that November 14, 2013, licensee amendment would not be implemented until 13 days after final reactor shutdown, which occurred on December 29, 2014.
Therefore, based on NRC approval of the License Amendment No. 262, dated February 12, 2015 (ADAMS Accession No. ML14304A588), "Issuance of Amendment - Eliminate Operability Requirements for Secondary Containment When Handling Sufficiently Decayed Irradiated Fuel or Fuel Cask," and as stated above, the proposed deletion of Section 3/4.7, "Station Containment Systems" TSs are acceptable.
3.3.11 Section 3/4.8, "Radioactive Effluents" Section 3/4.8 of the VY TSs, "Radioactive Effluents," contains the LCOs, actions, and SRs that assure that radioactive effluents are kept "as low as is reasonably achievable" in accordance with 10 CFR 50, Appendix I, "Numerical Guides for Design Objectives and Limiting Conditions for Operation to Meet the Criterion, 'As Low as is Reasonably Achievable,' for Radioactive Material in Light-Water-Cooled Nuclear Power Reactor Effluents," and, in any event, are within the dose limits for members of the public as specified in 10 CFR 20, "Standards for Protection Against Radiation," and applies to the release of all radioactive effluents from the plant. This section contains the following LCOs:
- Liquid Holdup Tanks
- Explosive Gas Mixture
The licensee proposes to renumber the section title, correct a typographical error in the title of current TS 3/4.8 and delete the "Explosive Gas Mixture" and "Steam Jet Air Ejector (SJAE)" TS LCOs, since they are only applicable to an operating reactor and do not apply to the permanently shutdown and defueled condition of VY.
TS 3/4.8.D, "Liquid Holdup Tanks," specifies the allowed quantities of radioactive material in the liquid holdup tanks. The licensee is not proposing any changes to this LCO.
TS 3/4.8.J, "Explosive Gas Mixture," specifies the limits and monitoring requirements for hydrogen concentration in the offgas downstream of the operating recombiner in the advanced offgas system. The hydrogen monitors are used to detect possible hydrogen buildups, which could result in a possible hydrogen explosion. This TS applies in all modes of normal operation.
TS 3/4.8.K, "Steam Jet Air Ejector (SJAE)," specifies limits on the gross radioactivity release rate of gases from the SJAE to provide reasonable assurance that the TEDE to an individual at the EAB will not exceed the limits of 10 CFR 50.67 in the event this effluent is inadvertently discharged directly to the environment without treatment. SJAEs are used to remove gases from the main condenser during normal reactor operation. This TS applies in all modes of normal operation.
Based on its review of the proposed changes, the NRC staff concludes that these TSs provide the LCOs, actions, and SRs necessary to that assure that radioactive effluents are kept as low as is reasonably achievable in accordance with 10 CFR 50, Appendix I, and are within the dose limits for members of the public specified in 10 CFR 20 when fuel is in reactor. Once the reactor is in the permanently defueled condition, hydrogen will no longer be produced by reactor operation and explosive gas mixture monitoring will no longer be required. The explosive gas mixture and SJAE are only important for a reactor authorized to operate or retain irradiated fuel in the reactor vessel. However, because 10 CFR 50.82(a)(2) prohibits the licensee from operating the reactor or placing fuel in the reactor vessel at VY, there is no reactor core and the explosive gas mixture and SJAE systems are no longer required.
The NRC staff also reviewed TS Section 3/4.8, "Explosive Gas Mixture," and "Steam Jet Air Ejector (SJAE)," which the licensee proposed for deletion, to ensure that these LCOs no longer satisfy the 10 CFR 50.36 criteria for inclusion in the TSs, as described in Section 2.0 of this SE.
The staff notes that these TSs indicate MODES for which the TSs are applicable. MODE, as defined in the TSs, is established by the mode-selector-switch. The reference to MODES for a permanently shutdown and defueled reactor, such as VY, is no required for reactor safety.
Because ENO has submitted certifications pursuant to 10 CFR 50.82(a)(2), it is prohibited from operating the reactor or placing fuel in the reactor vessel and VY is no longer in a configuration or a condition under which the TS MODES apply.
Based on the above, the staff finds that the proposed deletions of TS Section 3/4.8, "Explosive Gas Mixture" and "Steam Jet Air Ejector (SJAE)" are acceptable.
3.3.12 Section 3/4.10, "Auxiliary Electrical Power Systems" Section 3/4.10 of the VY TSs, "Auxiliary Electrical Power Systems," contains the LCOs, actions, and SRs that assure an adequate supply of electrical power for operation of those systems required for reactor safety. This section contains the following LCOs:
- Normal Operation
- Operation with Inoperable Components
- Diesel Fuel The licensee proposes to delete all of the above TSs LCOs, since they are only applicable to an operating reactor and do not apply to the permanently shutdown and defueled condition of VY.
TS 3/4.1 O.A, "Normal Operation," specifies requirements to ensure that the offsite power sources, the onsite standby power sources, emergency buses and RPS power protection provide sufficient capacity, capability, redundancy, and reliability to ensure the availability of necessary power to engineered safety features systems during and following DBAs so that the fuel, RCS, and containment design limits are not exceeded. This TS applies in Run and Startup/Hot Standby modes.
TS 3/4.10. B, "Operation With Inoperable Components," specifies requirements that ensure adequate power is available to operate the emergency safeguards equipment from the immediate access source or for minimum engineered safety features from either of the emergency DGs. This TS applies in Run and Startup modes with the reactor not in the cold condition.
TS 3/4.10.C, "Diesel Fuel," specifies the requirements for stored diesel fuel oil. Stored diesel fuel oil is required to have sufficient supply for 7 days of rated load operation for a single emergency DG. It also ensures the stored diesel fuel oil meets the quality standards. This TS applies in all modes of normal operation.
The NRC staff reviewed the proposed changes and concludes that these TSs provide the LCOs, actions, and SRs necessary to assure an adequate supply of electrical power for operation of those systems required for reactor safety. Under the provisions of 10 CFR 50.82(a)(2), placing fuel in the reactor vessel and resuming power operations are no longer authorized by the 10 CFR Part 50 license when the licensee submits a certification to the Commission that power operations have been permanently ceased and that the fuel has been permanently removed from the reactor vessel. In this condition, the operational conditions, transients, and postulated DBAs are no longer possible. Therefore, the systems required for reactor safety that the auxiliary electrical power systems were designed to power are no longer needed. The only OBA that could currently apply to the permanently shutdown and defueled VY reactor would be the FHA.
The licensee proposed a revision to the FHA in a letter dated November 14, 2013. (ADAMS Accession No. ML13323A518). The FHA analysis does not rely on normal or emergency power to mitigate the consequences of an FHA and alternating current and direct current sources are no longer required during movement of irradiated fuel assemblies for mitigation of a potential FHA. In the application of November 14, 2013, the licensee stated that the changes proposed
by this amendment would not be effective until 13 days after final reactor shutdown, which occurred on December 29, 2014, to allow for sufficient decay of the reactor fuel such that the fuel will no longer be considered recently irradiated, as defined in the FHA.
Therefore, the TSs contained in Section 3/4.10, which address auxiliary electrical power systems are no longer applicable. Furthermore, the accidents these systems and components were designed to mitigate are no longer possible, with the exception of the FHA. In the case of the FHA, the licensee stated that this licensee amendment would not be implemented until 13 days after final reactor shutdown. Therefore, based on NRC approval the License Amendment No. 262, dated February 12, 2015, "Issuance of Amendment - Eliminate Operability Requirements for Secondary Containment When Handling Sufficiently Decayed Irradiated Fuel or Fuel Cask," and that stated above, the proposed deletion of TSs related to auxiliary electrical power systems are acceptable.
The NRC staff also reviewed Section 3/4.10, "Auxiliary Electrical Power Systems," TSs proposed for deletion to ensure that these LCOs no longer satisfy the 10 CFR 50.36 criteria for inclusion in the TSs, as described in Section 2.0 of this SE. The staff notes that these TSs indicate MODES for which the TSs are applicable. MODE, as defined in the TSs, is established by the mode-selector-switch. The reference to MODES for a permanently shutdown and defueled reactor, such as VY, is no longer required for reactor safety. Because ENO has submitted certifications pursuant to 10 CFR 50.82(a)(2), it is prohibited from operating the reactor or placing fuel in the reactor vessel and VY is no longer in a configuration or a condition under which the TS MODES apply.
Based on the above, the NRC staff finds that the proposed deletions of TS Section 3/4.10 are acceptable.
3.3.13 Section 3/4.11, "Reactor Fuel Assemblies" Section 3/4.11 of the VY TSs, "Reactor Fuel Assemblies," contains the LCOs, actions, and SRs that assure the performance of the fuel rods. This section contains the following LCOs:
- Average Planar Linear Heat Generation Rate (APLHGR)
- Linear Heat Generation Rate (LHGR)
- Minimum Critical Power Ratio (MCPR)
The licensee proposes to delete all of the above TSs LCOs, since they are only applicable to an operating reactor and do not apply to the permanently shutdown and defueled condition of VY.
TS 3/4.11.A, "Average Planar Linear Heat Generation Rate (APLHGR)," specifies limits to ensure that the peak cladding temperature during a design-basis LOCA does not exceed 2200 degrees F. This TS applies in Run mode when greater or equal to 23 percent rated thermal power.
TS 3/4.11.B, "Linear Heat Generation Rate (LHGR)," specifies requirements for the LHGR of a fuel rod at a given nodal plane in a bundle. These limits are bundle type dependent and are monitored to assure all mechanical design requirements are met. This TS applies in Run mode when greater or equal to 23 percent rated thermal power.
TS 3/4.11.C, "Minimum Critical Power Ratio (MCPR)," specifies the MCPR operating limit, which is a cycle-dependent parameter that can be determined for a number of different combinations of operating modes, initial conditions, and cycle exposures in order to provide reasonable assurance against exceeding the fuel cladding integrity safety limit for potential abnormal occurrences. This TS applies in Run mode when greater or equal to 23 percent rated thermal power.
The NRC staff reviewed the proposed deletions and concludes that these TSs are only needed to provide the LCOs and SRs necessary to maintain reactor power and heat generation within the margins of conditions encountered during normal operation, anticipated occurrences, and for DBAs. The reactor fuel assemblies TSs are only important for a reactor authorized to operate. However, because 10 CFR 50.82(a)(2) prohibits the licensee from operating the reactor or placing fuel in the reactor vessel at VY, there is no reactor core generating power and the reactor fuel assemblies limits are no longer required for reactor safety.
The NRC staff has also reviewed Section 3/4.11 TSs proposed for deletion to ensure that these LCOs no longer satisfy the 10 CFR 50.36 criteria for inclusion in the TSs, as described in Section 2.0 of this SE. The staff notes that these TSs indicate MODES for which the TSs are applicable. MODE, as defined in the TSs, is established by the mode-selector-switch. The reference to MODES for a permanently shutdown and defueled reactor, such as VY, is no longer required for reactor safety. Because ENO has submitted certifications pursuant to 10 CFR 50.82(a)(2), it is prohibited from operating the reactor or placing fuel in the reactor vessel and VY is no longer in a configuration or a condition under which the TS MODES apply.
Based on the above, the NRC staff finds that the proposed deletions of TS Section 3/4.11 are acceptable.
3.3.14 Section 3/4.12, "Refueling and Spent Fuel Handling" Section 3/4.12 of the VY TSs, "Refueling and Spent Fuel Handling," contains the LCOs, actions, and SRs that assure core reactivity is within capability of the control rods, to prevent criticality during refueling, and to assure safe handling of spent fuel casks. This section contains the following LCOs:
- Refueling Interlocks
- Core Monitoring
- Fuel Storage Pool Water Level
- Control Rod and Control Rod Drive Maintenance
- Extended Core Maintenance
- Fuel Movement
- Spent Fuel Pool Water Temperature The licensee has proposed to:
- 1. Delete the Refueling Interlocks, Core Monitoring, Control Rod and Control Rod Drive Maintenance, Extended Core Maintenance, and Fuel Movement LCOs.
- 2. Revise the title of the Section 3/4.12.
- 3. Revise the applicability and objective for Section 3/4.12.
- 4. Revise 4.12.H Spent Fuel Pool Water Temperature.
- 5. Renumber Section 3/4.12.
3.3.14.1 Deletion of TSs: "Refueling Interlocks," "Core Monitoring," "Control Rod and Control Rod Drive Maintenance," "Extended Core Maintenance," and "Fuel Movement," LCOs The licensee proposes to delete the "Refueling Interlocks," "Core Monitoring," "Control Rod and Control Rod Drive Maintenance," "Extended Core Maintenance," and "Fuel Movement," TSs LCOs since they are only applicable to an operating reactor and do not apply to the permanently shutdown and defueled condition of VY.
TS 3/4.12.A, "Refueling Interlocks," specifies requirements for refueling interlocks and restriction of certain refueling procedures, such that, there is assurance that inadvertent criticality does not occur during refueling. This TS applies during in vessel fuel movements.
TS 3/4.12. B, "Core Monitoring," monitors the core reactivity condition during periods of station shutdown and refueling operations and guides the operator during refueling operations and station startup. This TS applies during core alterations.
TS 3/4.12.D, "Control Rod and Control Rod Drive Maintenance," specifies requirements for performing control rod/control rod drive maintenance and maintaining adequate shutdown margin during such activities to provide assurance that inadvertent criticality does not occur during such maintenance. This TS applies during in vessel fuel movements.
TS 3/4.12.E, "Extended Core Maintenance," specifies requirements for unloading of a portion of the reactor core for such purposes as inservice inspection requirements, examination of the core support plate, control rod, control rod drive maintenance, and provides assurance that inadvertent criticality does not occur during such operation. This TS applies during invessel fuel movements.
TS 3/4.12.F, "Fuel Movement," specifies requirements to assure that the reactor core has been shut down for at least 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> following power operation and prior to fuel handing or movement. This TS applies in all modes of normal operation.
The NRG staff reviewed these proposed changes in TS 3/4.12.A, TS 3/4.12.B, TS 3/4.12.D, TS 3/4.12. E, and TS 3/4. 12. F and concludes that these TS are only needed to provide the LCOs, actions, and SRs necessary to assure core reactivity is within capability of the control rods, and to prevent criticality during refueling operations. However, because 10 CFR 50.82(a)(2) prohibits the licensee from operating the reactor or placing fuel in the reactor vessel at VY, refueling is no longer allowed and these TSs are no longer required for reactor safety.
The NRG staff also reviewed TS Section 3/4.12, "Refueling Interlocks," "Core Monitoring,"
"Control Rod and Control Rod Drive Maintenance," "Extended Core Maintenance," and "Fuel Movement," which the licensee proposed for deletion to ensure that these LCOs no longer satisfy the 10 CFR 50.36 criteria for inclusion in the TSs, as described in Section 2.0 of this SE.
The staff notes that these TSs indicate MODES for which the TSs are applicable. MODE, as
defined in the TSs, is established by the mode-selector-switch. The reference to MODES is no longer required for a permanently shutdown and defueled reactor, such as VY. Because ENO has submitted certifications pursuant to 10 CFR 50.82(a)(2), it is prohibited from operating the reactor or placing fuel in the reactor vessel and VY is no longer in a configuration or a condition under which the TS MODES apply.
Based on the above, the NRC staff finds that the proposed changes to TS Section 3/4.12 are acceptable.
3.3.14.2 Section 3/4.12 Revised Title The current title of Section 3/4.12 is "Refueling and Spent Fuel Handling." The licensee is proposing to revise the title to "Spent Fuel Storage," so that it reflects that refueling of the reactor will no longer be possible.
The NRC staff reviewed this proposed change and concludes that because 10 CFR 50.82(a)(2) prohibits the licensee from operating the reactor or placing fuel in the reactor vessel at VY, refueling is no longer allowed and that the proposed change accurately describes this condition and is consistent with 10 CFR 50.82 for VY.
3.3.14.3 Section 3/4.12 Revised Applicability and Objective The current TS Section 3/4.12 Applicability and Objective are:
LCO 3.12 Applicability:
Applies to fuel handling, core reactivity limitations, and spent fuel handling.
LCO 3.12 Objective:
To assure core reactivity is within capability of the control rods, to prevent criticality during refueling, and to assure safe handling of spent fuel casks.
SR 4.12 Applicability:
Applies to periodic testing of those interlocks and instruments used during refueling.
SR 4.12 Objective:
To verify the operability of instrumentation and interlocks used in refueling.
The licensee proposes to revise and renumber the Applicability and Objective to:
LCO 3.2 Applicability:
Applies to storage of spent fuel.
LCO 3.2 Objective:
To assure safe storage of spent fuel.
SR4.2 Applicability:
Applies to the parameters which monitor the storage of spent fuel.
SR4.2 Objective:
To verify that spent fuel is being stored safely.
The NRC staff reviewed the proposed wording changes to Section 3/4.12 Applicability and Objective and concludes that they are consistent with the transition from an operating reactor to a permanently shutdown and defueled facility with a primary safety focus of safe storage of spent fuel. In addition, because 10 CFR 50.82(a)(2) prohibits the licensee from operating the reactor or placing fuel in the reactor vessel at VY, refueling is no longer allowed.
The NRC staff finds that the proposed changes stated above reflect the change in plant status and are appropriate. Therefore, the staff finds the proposed changes to be acceptable.
3.3.14.4 Revised SR4.12.H, "Spent Fuel Pool Water Temperature" TS 4.12. H currently states:
Whenever irradiated fuel is in the spent fuel pool, the pool water temperature shall be recorded daily. If the pool water temperature reaches 150°F, all refueling operations tending to raise the pool water temperature shall cease and measures taken immediately to reduce the pool water temperature below 150°F.
The licensee proposes to remove the word "refueling" from TS 4.12.H, so that it will state:
Whenever irradiated fuel is in the spent fuel pool, the pool water temperature shall be recorded daily. If the pool water temperature reaches 150°F, all operations tending to raise the pool water temperature shall cease and measures taken immediately to reduce the pool water temperature below 150°F.
Based on its review of the proposed changes, the NRC staff concludes that the change is consistent with the transition from an operating reactor to a permanently shutdown and defueled facility with a primary safety focus of safe storage of spent fuel. In addition, because 10 CFR 50.82(a)(2) prohibits the licensee from operating the reactor or placing fuel in the reactor vessel
at VY, refueling is no longer allowed. The staff finds that the proposed change reflects the change in plant status and is appropriate. Therefore, the proposed change is acceptable.
3.3.14.5 Section 3/4.12 Renumbering and Re-lettering The licensee proposes to renumber TS 3/4.12 to TS 3/4.2 and to re-letter TS 3/4.12.C and TS 3/4.12.H to TS 3/4.2.A and TS 3/4.2.B. The NRC staff reviewed the proposed changes and concludes that they are of a clarifying nature and do not change any technical requirements; therefore, these changes are acceptable.
3.3.15 Section 5.0, "Design Features" This section contains a description of the design features of the facility.
3.3.15.1 TS 5.1, "Site" The licensee proposes to retain this section in the TSs without modification or revision.
3.3.15.2 TS 5.2, "Reactor," TS 5.3, "Reactor Vessel," and TS 5.4, "Containment" These TSs provide a general description of the number of and design material requirements for the fuel, and control rod assemblies, in addition to the description of the reactor vessel, and the principal design parameters and applicable design codes for the reactor vessel, secondary, and primary containments. The licensee proposes to delete the requirements for fuel and control rod assemblies, since they are only applicable to an operating reactor and do not apply to the permanently shutdown and defueled condition of VY.
The three TSs to be deleted address the reactor, reactor vessel, and containment. These structures and systems serve to prevent or mitigate the consequences of postulated accidents involving the release of fission products. However, 10 CFR 50.82(a)(2) prohibits the licensee from operating the plant or placing fuel in the reactor vessel. In addition, the accidents these systems and components were designed to mitigate are no longer possible. Therefore, these TSs are no longer applicable.
Based on the above, the NRC staff finds that the proposed deletions of the design features TS sections, titled "Reactor," "Reactor Vessel," and "Containment" are acceptable.
3.3.15.3 Spent and New Fuel Storage This TS provides a general description of the new and spent fuel storage facilities.
The current title of TS Section 5.5 is "Spent and New Fuel Storage."
The licensee proposes to revise the title and renumber TS Section 5.5 to TS Section 5.2 "Spent Fuel Storage." The licensee also proposes to re-letter TS 5.5.8 to TS 5.5.A; TS 5.5.C to TS 5.5.B; TS 5.5.D to TS 5.5.C; and TS 5.5.E to TS 5.50.
Current TS 5.5.A states:
The new fuel storage facility shall be such that the effective multiplication factor (kett) of the fuel when dry is less than 0.90 and when flooded is less than 0.95.
The licensee proposes to delete the new fuel storage facility requirement, since the new fuel storage facility will not be used to store spent fuel and new fuel is no longer stored on site.
In addition, the licensee proposes to delete the reference to the new fuel storage facility in current TS 5.5.E as shown by the strikethrough below, and requests that License Condition 2.B be revised to no longer allow receipt of new fuel.
The maximum core geometry infinite lattice multiplication factor of any segment of the fuel assembly stored in the spent fuel storage pool or the new fuel storage fasHity shall be less than or equal to 1.31 at 20°C.
The NRC staff reviewed the proposed changes to the spent and new fuel storage requirements.
The licensee has permanently shutdown and defueled the reactor, and will no longer be receiving any new fuel onsite because 10 CFR 50.82(a)(2) prohibits the licensee from operating the plant or placing fuel in the reactor vessel at VY. In addition, as evaluated below, the licensee proposed that License Condition 2.B be revised to no longer allow receipt of new fuel.
Since the facility license will no longer allow new fuel to be stored onsite, the requirements for the new fuel storage facility are no longer applicable.
Based on the above, the staff finds that the proposed change to delete the new fuel storage facility requirements is acceptable.
3.3.16 Section 6.0, "Administrative Controls" This section contains a description of the administrative controls at the facility. The licensee proposed revision to or deletion of the administrative controls in a letter dated October 31, 2013 (ADAMS Accession Number ML13316A004). In this application the licensee proposed to remove portions of the TSs that are no longer applicable to the facility in its permanently defueled condition. Subsequently, the NRC approved the changes in Section 6.0 on December 22, 2014, by License Amendment No. 260 to Renewed Facility Operating License No. DPR-28 (ADAMS Accession No. ML14217A072).
Based on NRC approval of the requested changes by License Amendment No. 260 stated above, the proposed changes in this application are of a clarifying nature and do not change any technical requirements; therefore, these changes are acceptable. However, the current page numbers 255 through 267 in Section 6.0 will be renumbered to the new page numbers 12 through 20 as a result of this amendment.
3.4 Changes to Renewed Facility Operating License 3.4.1 Changes to License Condition a.

(1) managing the effects of aging on the functionality of structures and components that have been identified to require review under 10 CFR 54.21(a)(1) during the period of extended operation, and
(2) time-limited aging analyses that have been identified to require review under 10 CFR 54.21(c), such that there is reasonable assurance that the activities authorized by this renewed operating license will continue to be conducted in accordance with the current licensing basis, as defined in 10 CFR 54.3 for the facility, and that any changes made to the facility's current licensing basis in order to comply with 10 CFR 54.29(a) are in accordance with the Act and the Commission's regulations.
Revised License Condition h would state:
- h. Actions have been identified and have been or will be taken with respect to:
( 1) managing the effects of aging on the functionality of structures and components that have been identified to require review under 10 CFR 54.21 (a)(1) during the period of extended operation, and (2) time-limited aging analyses that have been identified to require review under 10 CFR 54.21 (c), such that there is reasonable assurance that the activities authorized by this license will continue to be conducted in accordance with the current licensing basis, as defined in 10 CFR 54.3 for the facility, and that any changes made to the facility's current licensing basis in order to comply with 10 CFR 54.29(a) are in accordance with the Act and the Commission's regulations.
Pursuant to 10 CFR 50.82(a)(2), as a result of the 10 CFR 50.82(a)(1 )(i) and 10 CFR 50.82(a)(1 )(ii) certifications submitted by the licensee, the 10 CFR Part 50 license for VY no longer authorize operation of the reactor. As such, reference to operation of the facility in License Conditions b, c, d, f, g, and hare inconsistent with the provisions of 10 CFR 50.82(a)(2). Therefore, the proposed changes provide consistency with 10 CFR 50.82(a)(2),
and are acceptable.
3.4.3 Changes to License Condition 2.A Current License Condition 2.A states:
A. Pursuant to Sections 104b of the Atomic Energy Act of 1954, as amended (the Act), and 10 CFR Part 50, "Licensing of Production and Utilization Facilities," Entergy Nuclear Vermont Yankee, LLC to possess and use, and Entergy Nuclear Operations, Inc., to possess, use, and operate the facility as a utilization facility at the designated location on the Entergy Nuclear Vermont Yankee, LLC site.
Revised License Condition 2.A would state:

Pursuant to Sections 104b of the Atomic Energy Act of 1954, as amended (the Act), and 10 CFR Part 50, "Licensing of Production and Utilization Facilities," Entergy Nuclear Vermont Yankee, LLC to possess and use, and Entergy Nuclear Operations, Inc., to possess and use the facility as a utilization facility at the designated location on the Entergy Nuclear Vermont Yankee, LLC site.
Pursuant to 10 CFR 50.82(a)(2), as a result of the 10 CFR 50.82(a)(1)(i) and 10 CFR 50.82(a)(1 )(ii) certifications submitted by the licensee, the 10 CFR Part 50 license for VY no longer authorize operation of the reactors. As such, reference to operation of the facility in License Condition 2.A is inconsistent with the limitation imposed on the licensee by 10 CFR 50.82(a)(2). Therefore, the proposed change provides consistency with 10 CFR 50.82(a)(2), and is acceptable.
3.4.4 Changes to License Condition 2.8 Current License Condition 2.8 states:
B. Entergy Nuclear Operations, Inc., pursuant to the Act and 10 CFR Part 70, to receive, possess, and use at any time special nuclear material as reactor fuel, in accordance with the limitations for storage and amounts required for reactor operation as described in the Final Safety Analysis Report, as supplemented and amended.
Revised License Condition 2. B would state:
B. Entergy Nuclear Operations, Inc., pursuant to the Act and 10 CFR Part 70, to possess at any time special nuclear material that was used as reactor fuel, in accordance with the limitations for storage and amounts required for reactor operation as described in the Final Safety Analysis Report, as supplemented and amended.
The licensee states the proposed revision to this license condition is consistent with the restrictions of 10 CFR 50.82(a)(2) that no longer authorizes operation or emplacement of fuel in the reactor vessel at VY.
The proposed change removes the authorization for receipt and use of special nuclear material (SNM) as reactor fuel and eliminates the reference to use of the SNM for reactor operations and limits the possession of SNM to SNM "that was used" as reactor fuel at VY. Pursuant to 10 CFR 50.82(a)(2) the 10 CFR Part 50 license for VY no longer authorizes operation of the reactor. As such, the licensee has no need to receive SNM in the form of reactor fuel and cannot use SNM as reactor fuel for reactor operations. The continued authorization to possess SNM "that was used" as reactor fuel is necessary as the licensee currently possesses the reactor fuel that was used for the past operations of the VY reactor. Based on the above, the proposed change to License Condition 2.8 is consistent with the permanently shutdown status of VY and is, therefore, acceptable.
3.4.5 Changes to License Condition 2.C Current License Condition 2.C states:
C. Entergy Nuclear Operations, Inc., pursuant to the Act and 10 CFR Parts 30, 40 and 70, to receive, possess, and use at any time any byproduct, source, and special nuclear material as sealed neutron sources for reactor startup,
sealed sources for calibration of reactor instrumentation and radiation monitoring equipment, and as fission detectors in amounts as required.
Revised License Condition 2.C would state:
C. Entergy Nuclear Operations, Inc., pursuant to the Act and 10 CFR Parts 30, 40 and 70, to receive, possess, and use at any time any byproduct, source, and special nuclear material as sealed neutron sources that were used for reactor startup, sealed sources that were used for calibration of reactor instrumentation and are used in radiation monitoring equipment, and as fission detectors in amounts as required.
The licensee proposed this license condition for revision to be consistent with the restriction of 10 CFR 50.82(a)(2) that VY is no longer authorized to operate. The proposed changes remove the authorization for receipt and use of byproduct, source, and SNM as sealed neutron sources for reactor startup but retains authorization to possess such sources previously used for reactor startup. The deletion of the authorization to receive and use sources for reactor startup is consistent with the fact that VY is no longer authorized to operate and the continued authorization to possess neutron sources that were used for reactor startup is consistent with the safe storage of byproduct, source, and SNM. As such the proposed changes to the VY License Condition 2. C is consistent with the permanently shutdown status of the facility and is, therefore, acceptable.
3.4.6 Changes to License Condition 3.A Current License Condition 3.A states:
A. Maximum Power Level Entergy Nuclear Operations, Inc. is authorized to operate the facility at reactor core power levels not to exceed 1912 megawatts thermal in accordance with the Technical Specifications (Appendix A) appended hereto.
Revised License Condition 3.A would state:
A. This paragraph deleted by Amendment No. 263.
The licensee stated that this license condition can be deleted because VY is permanently shutdown and defueled in accordance with 10 CFR 50.82(a)(2) and therefore power operation is no longer authorized.
The NRC staff reviewed the proposed deletion of License Condition 3.A and determined that power operation is no longer authorized at VY based on the licensee's 10 CFR 50.82(a)(2) certifications of being permanently shutdown and defueled. The licensee is not authorized to operate the VY at any power. Therefore, deletion of License Condition 3.A is appropriate and acceptable.
3.4.7 Changes to License Condition 3.F Current License Condition 3.F states:
F. Entergy Nuclear Operations, Inc. shall implement and maintain in effect all provisions of the approved Fire Protection Program as described in the Final Safety Analysis Report for the facility and as approved in the SER dated January 13, 1978, and supplemental SERs, dated 9/12/79, 2/20/80, 4/15/80, 713180, 10/24/80, 11/10/81, 1/13/83, 7/24/84, 3/25/86, 12/1/86, 12/8/89, 11 /29/90, 8/30/95, 3/23/97, 619197, 8/12/97, 316198, 3/31 /98, 9/2/98, and 2/24/99, subject to the following provisions:
Entergy Nuclear Operations, Inc. may make changes to the approved Fire Protection Program without prior approval of the Commission only if those changes would not adversely affect the ability to achieve and maintain safe shutdown in the event of a fire.
Revised License Condition 3. F would state:
F. This paragraph deleted by Amendment No. 263.
The licensee states that this license condition is based on maintaining an operational fire protection program in accordance with 10 CFR 50.48, "Fire protection," with the ability to achieve and maintain safe shutdown of the reactor in the event of a fire and is no longer applicable at VY. However, many of the elements that are applicable for the operating plant fire protection program continue to be applicable during plant decommissioning. During the decommissioning process, a fire protection program is required by 10 CFR 50.48(f) to address the potential for fires that could result in a radiological hazard. However, the regulation is applicable regardless of whether a requirement for a fire protection program is included in the facility license. Therefore, a license condition requiring such a program for a permanently shutdown and defueled plant is not needed.
The NRC staff finds that License Condition 3.F for VY, is based on maintaining fire protection programs that provides reasonable assurance that the ability to achieve and maintain safe shutdown in the event of a fire in accordance with 10 CFR 50.48. Achieving and maintaining safe shutdown in the event of a fire is no longer applicable to the decommissioned fire protection programs at VY since the facility is permanently shutdown and the fuel has been removed from the reactor. However, elements of the fire protection program (e.g, License Condition 3.N, Mitigating Strategy) continue during decommissioning to address fire events that could result in radiological hazards. The regulation in 10 CFR 50.48(f) requires VY to address the potential for fires, which could result in a radiological hazard. The NRC staff concludes that the rule, which requires a fire protection program, is sufficient to ensure that a program is maintained. Therefore, a license condition that also requires fire protection programs for the permanently shutdown and defueled unit is redundant. Based on the above, the NRC staff concludes that reliance on 10 CFR 50.48(f) is appropriate and the licensee's request to eliminate License Condition 3.F is acceptable.
3.4.8 Changes to License Condition 3.K Current License Condition 3.K states:
K. Minimum Critical Power Ratio When operating at thermal power greater than 1593 megawatts thermal, the safety limit minimum critical power ratio (SLMCPR) shall be established by adding 0.02 to the cycle-specific SLMCPR value calculated using the NRC-approved methodologies documented in General Electric Licensing Topical Report NEDE-24011-P-A, "General Electric Standard Application for Reactor Fuel," as amended, and documented in the Core Operating Limits Report.
Revised License Condition 3.K would state:
K. This paragraph deleted by Amendment No. 263.
The licensee stated that this license condition can be deleted because VY is permanently shutdown and defueled in accordance with 10 CFR 50.82(a)(2) and, therefore, power operation is no longer authorized.
The NRC staff concludes that power operation is no longer authorized at VY based on the licensee's 10 CFR 50.82(a)(2) certifications of being permanently shutdown and defueled. The proposed deletion is consistent with the lack of authority to operate at VY. Therefore, deletion of License Condition 3.K is appropriate and acceptable.
3.4.9 Changes to License Condition 3.L Current license condition 3.L states:
L. Transient Testing
- 1. During the extended power uprate (EPU) power ascension test program and prior to exceeding 168 hours0.00194 days <br />0.0467 hours <br />2.777778e-4 weeks <br />6.3924e-5 months <br /> of plant operation at the nominal full EPU reactor power level, with feedwater and condensate flow rates stabilized at approximately the EPU full power level, Entergy Nuclear Operations, Inc. shall confirm through performance of transient testing that the loss of one condensate pump will not result in a complete loss of reactor feedwater.
- 2. Within 30 days at nominal full-power operation following successful performance of the test in ( 1) above, through performance of additional transient testing and/or analysis of the results of the testing conducted in (1) above, confirm that the loss of one reactor feedwater pump will not result in a reactor trip.
Revised License Condition 3.L would state:
L. This paragraph deleted by Amendment No. 263.
The licensee stated that this license condition can be deleted because VY is permanently shutdown and defueled in accordance with 10 CFR 50.82(a)(2) and, therefore, power operation is no longer authorized.
Based on its review, the NRC staff concludes that power operation is no longer authorized at VY based on the licensee's previous submission of 10 CFR 50.82(a)(2) certifications of being permanently shutdown and defueled. The proposed deletion is consistent with the lack of authority to operate at VY. Therefore, deletion of License Condition 3.L is appropriate and acceptable.
3.4.1 O Changes to License Condition 3. M Current License Condition 3.M states:
M. Potential Adverse Flow Effects This license condition provides for monitoring, evaluating, and taking prompt action in response to potential adverse flow effects as a result of power uprate operation on plant structures, systems, and components (including verifying the continued structural integrity of the steam dryer).
- 1. The following requirements are placed on operation of the facility above the original licensed thermal power (OLTP) level of 1593 megawatts thermal (MWt):
- a. Entergy Nuclear Operations, Inc. shall monitor hourly the 32 main steam line (MSL) strain gages during power ascension above 1593 MWt for increasing pressure fluctuations in the steam lines.
- b. Entergy Nuclear Operations, Inc. shall hold the facility for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> at 105%, 110%, and 115% of OLTP to collect data from the 32 MSL strain gages required by Condition M.1.a, conduct plant inspections and walkdowns, and evaluate steam dryer performance based on these data; shall provide the evaluation to the NRC staff by facsimile or electronic transmission to the NRC project manager upon completion of the evaluation; and shall not increase power above each hold point until 96 hours0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> after the NRC project manager confirms receipt of the transmission.
- c. If any frequency peak from the MSL strain gage data exceeds the limit curve established by Entergy Nuclear Operations, Inc. and submitted to the NRC staff prior to operation above OLTP, Entergy Nuclear Operations, Inc. shall return the facility to a power level at which the limit curve is not exceeded. Entergy Nuclear Operations, Inc. shall
resolve the uncertainties in the steam dryer analysis, document the continued structural integrity of the steam dryer, and provide that documentation to the NRC staff by facsimile or electronic transmission to the NRC project manager prior to further increases in reactor power.
- d. In addition to evaluating the MSL strain gage data, Entergy Nuclear Operations, Inc. shall monitor reactor pressure vessel water level instrumentation or MSL piping accelerometers on an hourly basis during power ascension above OLTP. If resonance frequencies are identified as increasing above nominal levels in proportion to strain gage instrumentation data, Entergy Nuclear Operations, Inc. shall stop power ascension, document the continued structural integrity of the steam dryer, and provide that documentation to the NRC staff by facsimile or electronic transmission to the NRC project manager prior to further increases in reactor power.
- e. Following start-up testing, Entergy Nuclear Operations, Inc. shall resolve the uncertainties in the steam dryer analysis and provide that resolution to the NRC staff by facsimile or electronic transmission to the NRC project manager. If the uncertainties are not resolved within 90 days of issuance of the license amendment authorizing operation at 1912 MWt, Entergy Nuclear Operations, Inc. shall return the facility to OLTP.
- 2. As described in Entergy Nuclear Operations, Inc. letter BVY 05-084 dated September 14, 2005, Entergy Nuclear Operations, Inc. shall implement the following actions:
- a. Prior to operation above OLTP, Entergy Nuclear Operations, Inc. shall install 32 additional strain gages on the main steam piping and shall enhance the data acquisition system in order to reduce the measurement uncertainty associated with the acoustic circuit model (ACM).
- b. In the event that acoustic signals are identified that challenge the limit curve during power ascension above OLTP, Entergy Nuclear Operations, Inc. shall evaluate dryer loads and re-establish the limit curve based on the new strain gage data, and shall perform a frequency-specific assessment of ACM uncertainty at the acoustic signal frequency.
- c. After reaching 120% of OLTP, Entergy Nuclear Operations, Inc. shall obtain measurements from the MSL strain gages and establish the steam dryer flow-induced vibration load fatigue margin for the facility, update the dryer stress report, and re-establish the steam dryer monitoring plan (SDMP) limit curve with the updated ACM load
definition and revised instrument uncertainty, which will be provided to the NRC staff.
- d. During power ascension above OLTP, if an engineering evaluation is required in accordance with the SDMP, Entergy Nuclear Operations, Inc. shall perform the structural analysis to address frequency uncertainties up to +/-10% and assure that peak responses that fall within this uncertainty band are addressed.
- e. Entergy Nuclear Operations, Inc. shall revise the SDMP to reflect long-term monitoring of plant parameters potentially indicative of steam dryer failure; to reflect consistency of the facility's steam dryer inspection program with General Electric Services Information Letter 644, Revision 1; and to identify the NRC Project Manager for the facility as the point of contact for providing SDMP information during power ascension.
- f. Entergy Nuclear Operations, Inc. shall submit the final extended power uprate (EPU) steam dryer load definition for the facility to the NRC upon completion of the power ascension test program.
- g. Entergy Nuclear Operations, Inc. shall submit the flow-induced vibration related portions of the EPU startup test procedure to the NRC, including methodology for updating the limit curve, prior to initial power ascension above OLTP.
- 3. Entergy Nuclear Operations, Inc. shall prepare the EPU startup test procedure to include the (a) stress limit curve to be applied for evaluating steam dryer performance; (b) specific hold points and their duration during EPU power ascension; (c) activities to be accomplished during hold points; (d) plant parameters to be monitored; (e) inspections and walkdowns to be conducted for steam, feedwater, and condensate systems and components during the hold points; (f) methods to be used to trend plant parameters; (g) acceptance criteria for monitoring and trending plant parameters, and conducting the walkdowns and inspections; (h) actions to be taken if acceptance criteria are not satisfied; and (i) verification of the completion of commitments and planned actions specified in its application and all supplements to the application in support of the EPU license amendment request pertaining to the steam dryer prior to power increase above OLTP. Entergy Nuclear Operations, Inc. shall provide the related EPU startup test procedure sections to the NRC by facsimile or electronic transmission to the NRC project manager prior to increasing power above OLTP.
- 4. When operating above OLTP, the operating limits, required actions, and surveillances specified in the SDMP shall be met. The following key attributes of the SDMP shall not be made less restrictive without prior NRC approval:
- a. During initial power ascension testing above OLTP, each test plateau increment shall be approximately 80 MWt;
- b. Level 1 performance criteria; and
- c. The methodology for establishing the stress spectra used for the Level 1 and Level 2 performance criteria.
Changes to other aspects of the SDMP may be made in accordance with the guidance of NEI 99-04.
- 5. During each of the three scheduled refueling outages (beginning with the spring 2007 refueling outage), a visual inspection shall be conducted of all accessible, susceptible locations of the steam dryer, including flaws left "as is" and modifications.
- 6. The results of the visual inspections of the steam dryer conducted during the three scheduled refueling outages (beginning with the spring 2007 refueling outage) shall be reported to the NRC staff within 60 days following startup from the respective refueling outage. The results of the SDMP shall be submitted to the NRC staff in a report within 60 days following the completion of all EPU power ascension testing.
- 7. The requirements of paragraph 4 above for meeting the SDMP shall be implemented upon issuance of the EPU license amendment and shall continue until the completion of one full operating cycle at EPU. If an unacceptable structural flaw (due to fatigue) is detected during the subsequent visual inspection of the steam dryer, the requirements of paragraph 4 shall extend another full operating cycle until the visual inspection standard of no new flaws/flaw growth based on visual inspection is satisfied.
- 8. This license condition shall expire upon satisfaction of the requirements in paragraphs 5, 6, and 7 provided that a visual inspection of the steam dryer does not reveal any new unacceptable flaw or unacceptable flaw growth that is due to fatigue.
Revised License Condition 3.M would state:
M. This paragraph deleted by Amendment No. 263.
The licensee stated that this license condition can be deleted in its entirety because VY is permanently shutdown and defueled in accordance with 10 CFR 50.82(a)(2) and, therefore, power operation is no longer authorized.
The NRC staff reviewed the proposed deletion of License Condition 3.M and concludes that power operation is no longer authorized at VY based on the licensee's 10 CFR 50.82(a)(2) certifications of being permanently shutdown and defueled. The licensee is not authorized to
operate at VY at any power. In addition, the steam dryer performs the function of removing moisture from the wet steam exiting the steam generators during reactor operation and serves no function in the permanently shutdown and defueled condition. Therefore, deletion of license condition 3.M is appropriate and acceptable.
3.4.11 Changes to License Condition 3.0 Current License Condition 3.0 states:
- 0. The licensee shall implement and maintain all Actions required by Attachment 2 to NRC Order EA-06-137, issued June 20, 2006, except the last action that requires incorporation of the strategies into the site security plan, contingency plan, emergency plan and/or guard training and qualification plan, as appropriate.
Revised License Condition 3.0 would state:
- 0. This paragraph deleted by Amendment No. 263.
The licensee stated that this license condition can be deleted because VY is permanently shutdown and defueled in accordance with 10 CFR 50.82(a)(2) and, therefore, power operation is no longer authorized.
The NRC staff reviewed the proposed deletion of License Condition 3.0 and concludes that the OBA on which this order was based is not a postulated accident that can occur in the permanently defueled condition, rendering the actions required by the order and this license condition, unnecessary. In addition the NRC has approved ENO's request to rescind Order EA-06-137 on December 13, 2014 (ADAMS Accession No. ML14227A912). Therefore, deletion of License Condition 3.0, is appropriate and acceptable.
3.4. 12 Changes to License Condition 3. R Current License Condition 3. R states:
R. Entergy Nuclear Vermont Yankee, LLC and Entergy Nuclear Operations, Inc.
shall implement the most recent staff-approved version of the Boiling Water Reactor Vessels and Internals Project (BWRVIP) Integrated Surveillance Program (ISP) as the method to demonstrate compliance with the requirements of 10 CFR Part 50, Appendix H. Any changes to the BWRVIP ISP capsule withdrawal schedule must be submitted for NRC staff review and approval. Any changes to the BWRVIP ISP capsule withdrawal schedule which affects the time of withdrawal of any surveillance capsules must be incorporated into the licensing basis. If any surveillance capsules are removed without the intent to test them, these capsules must be stored in a manner which maintains them in a condition which would support re-insertion into the reactor pressure vessel, if necessary.
Revised License Condition 3.R would state:
R. This paragraph deleted by Amendment No. 263.
The licensee stated that this license condition can be deleted because VY is permanently shutdown and defueled in accordance with 10 CFR 50.82(a)(2) and, therefore, power operation is no longer authorized. The requirements in Appendix Hare only applicable to nuclear plants that are performing power operations in the reactor critical operating mode because: (a) this is the plant operating mode that produces high energy neutrons as a result of the reactor's nuclear fission process, and (b) the requirements are set in place to provide assurance that the reactor pressure vessel (RPV) will maintain adequate levels of fracture toughness throughout the operating life of the reactor.
Based on its review of the proposed deletion, the NRC staff concludes that continued implementation of the applicable surveillance capsule testing and reporting requirements are no longer necessary for VY because: (a) power operation is no longer authorized at VY based on the 10 CFR 50.82(a)(2) certifications, and (b) from a fracture toughness perspective, the VY RPV will cease to be exposed to further irradiation by high energy neutrons or subjected to any high thermal stress environments, as induced by operating the RCS at an elevated temperature.
The removal, testing, reporting, and storage requirements for reactor vessel surveillance capsules and their test specimens do not need to be implemented further since VY has permanently ceased power operations. Therefore, deletion of License Condition 3. R is appropriate and acceptable.
3.4.13 Changes to License Condition 3.S Current License Condition 3.S states:
S. Steam Dryer License Condition Entergy Nuclear Vermont Yankee, LLC and Entergy Nuclear Operations, Inc.
shall perform and implement the continuous parameter monitoring, moisture content monitoring, and visual inspections of the steam dryer described in BWRVIP-139-A, Final Report, dated July 2009, with the additional requirements included in the license condition specified herein.
- 1. The licensee shall inspect the steam dryer during refueling outage (RFO) 31. If the steam dryer inspection results from RFO 31 demonstrate that (a) any new cracking due to either fatigue or intergranular stress-corrosion cracking (IGSCC) is not significant (ie., is evaluated to be acceptable without repair), and (b) all previously identified indications (including the new indication identified in RFO 27) show no crack growth requiring repair, the licensee shall initiate a program to perform steam dryer inspections at least every third refueling outage.
- 2. If the steam dryer inspection during RFO 31 or any subsequent steam dryer inspection reveals new cracking due to either fatigue or IGSCC that
requires repair, or any growth of existing cracking that requires repair, the licensee shall inspect the steam dryer during each refueling outage.
- 3. The steam dryer inspection during RFO 31 and all future steam dryer inspections shall meet the guidelines in BWRVIP-139-A with the exception of the inspection interval specified in BWRVI P-139-A. The results of the steam dryer inspection beginning with RFO 31 and continuing for all future inspections shall be submitted to the NRC within 6 months of each steam dryer inspection completion.
- 4. This license condition shall continue for the full term of the period of extended operation unless duly amended.
Revised License Condition 3.S would state:
S. This paragraph deleted by Amendment No. 263.
The licensee stated that this license condition can be deleted because VY is permanently shutdown and defueled in accordance with 10 CFR 50.82(a)(2) and, therefore, power operation is no longer authorized.
The NRC staff reviewed the proposed deletion of License Condition 3.S. The steam dryer performs the function of removing moisture from the wet steam exiting the steam separators during reactor operation and serves no function in the shutdown condition. As noted above, power operation is no longer authorized at VY based on the licensee's 10 CFR 50.82(a)(2) certifications of being permanently shutdown and defueled. Therefore, deletion of License Condition 3.S for the steam dryer monitoring and inspection program is appropriate and acceptable.
3.4.13 Changes to License Condition 4 Current License Condition 4 states:
- 4. This renewed operating license is effective as of the date of issuance and shall expire at midnight on March 21, 2032.
Revised License Condition 4 would state:
- 4. This license is effective as of the date of issuance and is effective until the Commission notifies the licensee in writing that the license is terminated.
The licensee stated that this license condition is revised to reflect the permanently defueled condition at the facility in accordance with 10 CFR 50.82(a)(2). ENO has proposed that this license condition be revised to conform to 10 CFR 50.51, "Continuation of license," in that the license authorizes ownership and possession of VY until the Commission notifies the licensee in writing that the license is terminated.
The NRC staff reviewed the proposed Licensee Condition 4. The current License Condition 4, which documents the date of the expiration of the renewed license, is no longer necessary for a permanently shutdown condition of the plant in the process of decommissioning. The revised License Condition 4 documents the current condition of the plant and summarizes the actions and requirements applicable to the facility by 10 CFR 50.51. The revised License Condition 4 is consistent with the regulatory requirements applicable to the facility in the permanently shutdown and defueled condition. Therefore, the revised License Condition 4 is appropriate and acceptable.
3.5 Continued Safe Operations of the SFP As stated above, 10 CFR 50.51 (b) requires licensees to take actions necessary to decommission and decontaminate the facility and continue to maintain the facility in a safe condition. The structures and components required to maintain the facility during the decommissioning period may remain operational beyond the normal licensed operating period of 40 years and the 20 year renewal period previously authorized at VY. Under the provisions of 10 CFR 50.82, the licensee must complete decommissioning within 60 years of permanent cessation of operations. Long lived passive structures and components, such as those used to maintain the SFP, may remain in operation up to 60 years after the permanent cessation of operations.
The licensee currently has a neutron absorber monitoring program for the SFP in its UFSAR as a part of License Renewal Commitment 52. This program requires the license to perform testing either via coupon measurement and/or via neutron attenuation testing using an in situ method every 10 years. The testing includes periodic verification of boron loss through areal density measurement of coupons or through direct in situ techniques, such as measurement of boron areal density, measurement of geometric changes in the material (blistering, pitting, and bulging), and detection of gaps through blackness testing. The NRC reviewed and approved this program and the UFSAR description of the program as part of the license renewal review.
As described in NRC Regulatory Issue Summary 2014-09: "Maintaining the Effectiveness of License Renewal Aging Management Programs," dated August 6, 2014 (ADAMS Accession No. ML14058A398), holders of licenses issued under 10 CFR Part 54 are required to maintain the effectiveness of their aging management programs and activities. The licensee is obligated to maintain the effectiveness of the neutron absorber monitoring program described in its UFSAR.
As such, the licensee's existing neutron absorbing material monitoring program, described in the UFSAR, is adequate for managing the effects of aging in the SFP.
The first test using this program was performed in September and October of 2014 using the Boron-10 Areal Density Gage for Evaluating Racks (BADGER) method. The measured panels had a measured average panel areal density values above the minimum required areal density, which is an acceptable result.
In addition, in its supplemental letter dated May 4, 2015, the licensee stated that all fuel in the SFP is scheduled to be removed from the SFP to dry fuel storage by December 31, 2020, which is 4 years before the next neutron attenuation test is due.
The changes proposed by the licensee for the Section 3/4.12, "Spent Fuel Storage" TSs do not affect the design or use of the existing fuel racks, and therefore no criticality analysis was made.
The systems needed to keep the fuel in the SFP in a subcritical condition are also kept intact.
TS 3/4.12.C, "Fuel Storage Pool Water Level" and TS 3/4.12.H, "Spent Fuel Pool Water Temperature" requirements for safe storage of spent fuel are retained. The NRC staff concludes that either removing all fuel by December 31, 2020, or thereafter continuing the current program as stated in the UFSAR, is acceptable to ensure continued safe operation of the SFP during the decommissioning period.
4.0 STATE CONSULTATION
In accordance with the Commission's regulations, the Vermont State official was notified of the proposed issuance of the amendment. The State official had no comments.
5.0 ENVIRONMENTAL CONSIDERATION
The amendment changes a requirement with respect to the installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 and changes surveillance requirements. The NRC staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration, and there has been no public comment on such finding, which was published in the Federal Register on February 17, 2015 (80 FR 8358). The amendment also relates to changes in recordkeeping, reporting, or administrative procedures or requirements. Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9) and 10 CFR 51.22(c)(1 O)(ii).
Pursuant to 10 CFR 51.22(b) no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment.
6.0 CONCLUSION
The Commission has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) there is reasonable assurance that such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
