HOPE CREEK 1-7 Amendment No. 208
UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 208 TO RENEWED FACILITY OPERATING LICENSE NO. NPF-57 PSEG NUCLEAR LLC HOPE CREEK GENERATING STATION DOCKET NO. 50-354
1.0 INTRODUCTION
By letter dated March 27, 2017 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML17086A071 ), PSEG Nuclear LLC (the licensee) requested changes to the Hope Creek Generating Station (Hope Creek) Technical Specifications (TSs).
Specifically, the licensee requested to adopt U.S. Nuclear Regulatory Commission (NRC or the Commission)-approved Technical Specifications Task Force (TSTF) Improved Standard Technical Specifications Change Traveler TSTF-535, Revision 0, "Revise Shutdown Margin Definition to Address Advanced Fuel Designs" (ADAMS Accession No. ML112200436), dated August 8, 2011.
The proposed change would revise the TS definition of shutdown margin (SDM) to require calculation of SDM at the reactor moderator temperature corresponding to the most reactive state throughout the operating cycle (68 degrees Fahrenheit (°F) or higher). The purpose is to address newer boiling-water reactor (BWR) fuel designs, which may be more reactive at shutdown temperatures above 68 °F.
The licensee stated that it did not propose any significant variations or deviations from the TS changes as described in TSTF-535 or the applicable parts of the NRC staff's model safety evaluation. The availability of this TS improvement was announced in the Federal Register on February 26, 2013 (78 FR 13100), as part of the consolidated line item improvement process.
2.0 REGULATORY EVALUATION
2.1 Background In water-moderated reactors, water is used to slow down, or moderate, high energy fast neutrons to low energy thermal neutrons through multiple scattering interactions. The low energy thermal neutrons are much more likely to cause fission when absorbed by the fuel.
However, not all of the thermal neutrons are absorbed by the fuel; a portion of them are instead absorbed by the water moderator. The amount of moderator and fuel that is present in the core heavily influences the fractions of thermal neutrons that are absorbed.
Enclosure 2
Water-moderated reactors are designed such that they tend to operate in what is known as an under-moderated condition. In this condition, the ratio of the moderator-to-fuel in the core is small enough that the overall effectiveness of water as a moderator decreases with increasing temperature. As temperature increases, fewer neutrons are absorbed in the moderator due to the decrease in its density (i.e., lost to the reaction). At the same time, this increase in reactivity is overshadowed by fewer neutrons being moderated (i.e., slowed enough to cause fissions),
which reduces overall reactivity. The result is a decrease in power and temperature, which produces a negative reactivity feedback effect so that the reactor becomes self-regulating.
However, if the amount of moderator becomes too large with respect to the amount offuel, the reactor can enter an over-moderated condition. In this condition, the o\erall effectiveness of water as a moderator increases with the temperature. The number of neutrons moderated (i.e., slowed down) enough to cause fission outweighs the loss of neutrons being absorbed in the moderator. This causes an increase in power that leads to a further increase in temperature, creating a potentially dangerous positive reactivity feedback cycle.
As practical examples in support of the proposed changes to the definition of SOM, TSTF-535 discussed SDM with regard to fuel assembly-GE14 (GE14) and Global Nuclear Fuel-2 (GNF2) fuels. TSTF-535 indicated that for historical fuel products leading up to and including GE 14, the maximum reactivity condition for SOM always occurred at a moderator temperature of 68 °F.
These fuel products were designed so that the core is always under-moderated when all control rods are inserted, except for the single most reactive rod. In cores with GNF2 fuel, TSTF-535 projected that the maximum reactivity condition at the beginning of cycle will remain at 68 °F, but later in the cycle, the most limiting SOM may occur at a higher temperature. Thus, the GNF2 fuel design could potentially cause an over-moderated condition in the core.
2.2 Technical Specification Changes The licensee's adoption of TSTF-535 for Hope Creek proposes to revise the TS definition of SOM to require calculation of SOM at the reactor moderator temperature corresponding to the most reactive state throughout the operating cycle (68 °F or higher).
The curr.ent definition of SOM in Section 1.0, "Definitions," of Hope Creek TSs is:
SHUTDOWN MARGIN 1.40 SHUTDOWN MARGIN shall be the amount of reactivity by which the reactor is subcritical or would be subcritical assuming all control rods are fully inserted except for the single control rod of highest reactivity worth which is assumed to be fully withdrawn and the reactor is in the shutdown condition; cold, i.e. 68°F; and xenon free.
The licensee proposed to delete the current definition of SOM stated above and replace it with the following definition in accordance with TSTF-535:
SHUTDOWN MARGIN (SOM) 1.40 SOM shall be the amount of reactivity by which the reactor is subcritical or would be subcritical throughout the operating cycle assuming that:
- a. The reactor is xenon free;
- b. The moderator temperature is~ 68 °F, corresponding to the most reactive state; and
- c. All control rods are fully inserted except for the single control rod of highest reactivity worth, which is assumed to be fully withdrawn.
With control rods not capable of being fully inserted, the reactivity worth of these control rods must be accounted for in the determination of SOM.
The licensee also proposed to add "(SOM)" next to the title, 'SHUTDOWN MARGIN," to show it is now an abbreviated term.
2.3 Regulatory Review Title 10 of the Code of Federal Regulations ( 10 CFR), Part 50 Appendix A, General Design Criteria for Nuclear Power Plants" (GDC) 26, "Reactivity control system redundancy and capability," and GDC 27, "Combined reactivity control systems capability," respectively state that reactivity within the core is to be controllable to ensure subcriticality is achievable and maintainable under cold conditions. Reactivity must also have appropriate margin for stuck rods and it must be controllable to assure that under postulated accident conditions, the capability to cool the core is maintained.
In addition, 10 CFR 50.36(c )(2)(ii) requires the establishment of a limiting condition for operation (LCO) 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 TS definition of SOM and the LCOs placed on SOM serve, in part, to satisfy GDCs 26 and 27. They ensure there is always sufficient negative reactivity worth available to offset the positive reactivity worth of changes in moderator and fuel temperature, the decay of fission product poisons, the failure of a control rod to insert, and reactivity insertion accidents. Given this margin, the core can be held subcritical for conditions of normal operation, including anticipated operational occurrences.
The NRC's guidance for the format and content of the licensee's TSs can be found in NUREG-1433, Revision 4, "Standard Technical Specifications General Electric Plants (BWR/4)"
(STSs).
Revision 3 of NUREG-0800, "Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR [Light-Water Reactor] Edition," Section 4.3, "Nuclear Design,"
Revision 3, dated March 2007 (ADAMS Accession No. ML070740003), provides the procedures concerning the review of control systems and SOM to help ensure compliance with GDCs 26 and 27.
3.0 TECHNICAL EVALUATION
3.1 Current Definition of Shutdown Margin In BWR plants, the control rods are used to hold the reactor core subcritical under cold conditions. The control rod negative reactivity worth must be sufficient to ensure the core is subcritical by a margin known as the SOM. It is the additional amount of negative reactivity worth needed to maintain the core subcritical by offsetting the positive reactivity worth that can occur during the operating cycle due to changes in moderator and fuel temperature, the decay of
fission product poisons, the failure of a control rod to insert, and reactivity insertion accidents.
Specifically, Section 1.0, "Definitions," of the STSs defines SOM as the amount of reactivity by which the reactor is subcritical or would be subcritical, assuming that the reactor is (1) xenon free, (2) the moderator is 68 °F, and (3) all control rods are fully inserted except for the rod of highest worth, which is assumed to be fully withdrawn.
The three criteria provided in the definition help exemplify what has traditionally been the most reactive design condition for a reactor core. Xenon is a neutron poison produced by fission product decay, and its presence in the core adds negative reactivity worth. Assuming the core is xenon free removes a positive reactivity offset and is representative of fresh fuel at the beginning of cycle.
The minimum temperature the reactor moderator is anticipated to experience is 68 °F, making it the point at which the moderator will be at its densest and, therefore, capable of providing the highest positive reactivity worth. By assuming the highest \f\.Orth rod is fully withdrawn, the core can be designed with adequate SOM to ensure it remains safely shut down, even in the event of a stuck control rod, as specified in GDCs 26 and 27.
Determination of the SOM under the aforementioned conditions yields a conservative result that, along with the requirements set forth in Hope Creek's TS 3/4.1.1, "Shutdown Margin,"
LCO 3.1.1, helps ensure:
(a) the reactor can be made subcritical from all operating conditions and transients and design-basis events, (b) the reactivity transients associated with postulated accident conditions are controllable within acceptable limits, and (c). the reactor will be maintained sufficiently subcritical to preclude inadvertent criticality in the shutdown condition.
3.2 Proposed Definition of Shutdown Margin The specified moderator temperature of 68 °F facilitates the maximum reactivity condition only if the core exists in an under-moderated condition. In addition to burnable poisons, many modem fuel designs also incorporate partial length rods for increased neutron economy, which are employed in order to extend the operating cycle. Both of these affect the ratio of moderator to fuel. The strong local absorption effects of the burnable poisons in fresh fuel make the core under-moderated. As burnable poisons are depleted during the fuel cycle, the core becomes less under-moderated, potentially leading to a slightly over-moderated condition wherein the core will be more reactive at a moderator temperature higher than the 68 °F specified in the SOM definition. Thus, the maximum core reactivity condition and the most limiting SDM may occur later in the fuel cycle at a temperature greater than 68 °F. Consequently, calculation of the SOM at the currently defined moderator temperature of 68 °F may not accurately determine the available margin.
Consistent with TSTF-535, the licensee proposed a change to the definition of SDM to enable calculation of the SOM at a reactor moderator temperature of 68 °F or a higher temperature corresponding to the most reactive state throughout the operating cycle. SDM would be calculated using the appropriate limiting conditions for all fuel types at any time in core life.
In support of the proposed change, TSTF-535 cited the requirements for SOM as specified in Topical Report NED0-24011-A, Revision 18, "General Electric Standard Application for Reactor Fuel (GESTAR II, Main)," dated April 2011 (ADAMS Accession No. ML111120046).
Section 3.2.4.1, "Shutdown Reactivity," of GESTAR II states, in part:
The core must be capable of being made subcritical, with margin, in the most reactive condition throughout the operating cycle with the most reactive control rod fully withdrawn and all other rods fully inserted.
TSTF-535, Revision 0, also cites SRP Section 4.3, which states, in part, the following, concerning the review of control systems and SOM:
The adequacy of the control systems to assure that the reactor can be returned to and maintained in the cold shutdo'Ml condition at any time during operation. The applicant shall discuss shutdown margins (SOM). Shutdown margins need to be demonstrated by the applicant throughout the fuel cycle.
Although the licensing basis requirements for SOM in GESTAR II are only applicable for cores licensed with GNF methods, they are consistent with the review procedures set forth in the SRP, which are provided to help ensure compliance with GDCs 26 and 27.
While the SRP does not prescribe the temperature at which the minimum SOM should be determined, the requirement of shutting down the reactor and maintaining it in a shutdo'Ml condition "at any time during operation" suggests that considering a range of thermal and exposure conditions would be appropriate in the determination of the minimum SOM. Because newer fuel designs employ elements such as partial length rods and burnable absorbers that may cause the maximum core reactivity conditions and the most limiting SOM to occur later in the fuel cycle at a temperature greater than 68 °F, the NRC staff agrees with the TSTF-535 assessment in this regard. Additionally, the NRC staff finds that allowing calculation of the SOM at the most limiting core reactivity condition is prudent with respect to ensuring compliance with GDCs 26 and 27 and concludes that the proposed changes to the Hope Creek TSs are acceptable.
The drive for TSTF-535 was to provide for a more broadly applicable SOM definition in recognition of modern fuel designs for which the core may not be in its most reactive condition at 68 °F. The proposed language would require the licensee to consider all temperatures equal to or exceeding 68 °F and all times in the operating cycle. This change places an additional responsibility on any implementing licensee to identify the most limiting time-in-cycle and temperature, a change that is effectively more restrictive than the current definition. Therefore, the change can be considered acceptable for any facility that currently adheres to the current definition of SOM that is contained in the STSs. Based on these considerations, the NRC staff concludes that the change is applicable to any BWR, regardless of its fuel design. The NRC staff also concludes that the revised definition is consistent with the 10 CFR 50.36 requirements pertaining to LCOs, because it ensures that the LCOs for SOM consider a broadly conservative range of potential initial conditions in the anticipated operational occurrence analyses.
3.3 Technical Evaluation Summary The NRC staff has reviewed the licensee's implementation of the TSTF-535 proposed revisions to the definition of SOM. Based on the considerations discussed above, the NRC staff concludes that the proposed revisions are acceptable and will provide a conservative and
improved approach to the calculation of SOM that ensures use of the appropriate limiting conditions for all fuel types at any time in the life of the core. The NRC staff concludes the proposed revisions serve to satisfy the requirements set forth in GDCs 26 and 27, as discussed in SRP, Section 4.3. Additionally, the NRC staff concludes the proposed changes to the definition of SOM would require the licensee to calculate SOM in consideration of the most limiting conditions in the core. Therefore, the revised SOM definition is acceptable for BWR facilities using any current fuel design, and specifically, for Hope Creek.
