Exelon Generation Company, LLC (Exelon) requests an amendment to Renewed Facility Operating License Number DPR-16 for Oyster Creek Nuclear Generating Station (OCNGS).
The proposed amendment would revise the effective and implementation dates of License Amendment No. 294, Permanently Defueled Emergency Plan (PDEP) and Emergency Action Level (EAL) scheme for the permanently defueled condition. The proposed changes are being submitted to the U.S. Nuclear Regulatory Commission (NRC) for approval prior to implementation.

The proposed changes are being submitted to the U.S. Nuclear Regulatory Commission (NRC) for approval prior to implementation.
On September 17, 2018, OCNGS permanently ceased power operations (Reference 1). By letter dated September 25, 2018, (Reference 2), Exelon certified that all fuel had been permanently removed from the OCNGS reactor vessel and placed in the spent fuel pool (SFP).

On October 17, 2018, the NRC approved License Amendment No. 294, OCNGS PDEP and Permanently Defueled EAL Scheme (Reference 3). The PDEP and Permanently Defueled EAL scheme were predicated on approval of requests for Exemptions from portions of 10 CFR 50.47(b), 10 CFR 50.47(c)(2), and 10 CFR Part 50, Appendix E, Section IV, which were approved on October 16, 2018 (Reference 4).

The PDEP and Permanently Defueled EAL scheme were predicated on approval of requests for exemptions from portions of 10 CFR 50.47(b), 10 CFR 50.47(c)(2), and 10 CFR Part 50, Appendix E, Section IV, approved in Reference 4. The PDEP reduces the scope of offsite and onsite emergency planning commensurate with the permanently defueled condition.

The PDEP reduces the scope of offsite and onsite emergency planning commensurate with the permanently defueled condition.
The basis for the approval of the exemptions from offsite emergency preparedness (EP) requirements included a site-specific analysis that showed that the fuel stored in the SFP would not reach the zirconium ignition temperature in fewer than 1O hours from the time at which it was assumed a loss of both water and air cooling of the spent fuel (zirc-fire window). Exelon's site-specific analyses for OCNGS, as provided in Exelon's exemption request (Reference 5),

Since the time of the submittal of the original adiabatic calculation in Reference 5, two key assumptions have been reconsidered based on actual conditions at the time of final shutdown.
Since the time of the submittal of the original adiabatic calculation in Reference 5, two key assumptions have been reconsidered based on actual conditions at the time of final shutdown.
First, the fuel in the reactor at the time of the final shutdown (Cycle 26) was considered instead of projected next cycle fuel (Cycle 27). As provided in Reference 6, the conditions through the end of Cycle 26 result in less decay heat in its limiting bundle than the limiting bundle used from Cycle 27. Second, the masses of fuel bundle assembly hardware pieces, such as the channel box and tie plates are credited, which reduces the required decay time.

However, Exelon decided to reschedule the final shutdown to no later than October 31, 2018 (Reference 2), at the end of the current two-year operating cycle (Cycle 26). A revised adiabatic calculation (provided in ) was performed that calculates new decay heat values and the required decay time based on the revised final shutdown date at OCNGS, which no longer includes Cycle 27, such that, Cycle 26 becomes the final and bounding reload.

The revised decay time is consistent with NRC's stated generic time for Boiling Water Reactors (BWRs) as documented in NUREG/CR-6451 BNL-NUREG-52498, "A Safety and Regulatory Assessment of Generic BWR and PWR [Pressurized Water Reactor] Permanently Shutdown Nuclear Power Plants" (Reference 8) and the Regulatory Basis document for "Regulatory Improvements for Power Reactors Transitioning to Decommissioning" (Reference 9). Oyster Creek is a lower power density plant than the BWR referenced in above documents; therefore, OCNGS would be expected to have a site-specific calculation that would be less than the generic required decay time.

294, PDEP, Permanently Shutdown EAL scheme, and associated Exemptions at 9.38 months (285 days) is commensurate with the hazards associated with a permanently shutdown and defueled facility based on the updated site-specific analysis that showed the fuel stored in the SFP would not reach the zirconium ignition temperature in fewer than 1O hours from the time at which it was assumed a loss of both water and air cooling of the spent fuel. The proposed change does not involve installation of new equipment or modification of existing equipment, so that no new equipment failure modes are introduced. In addition, the proposed change does not result in a change to the way that the equipment or facility is operated so that no new or different kinds of accident initiators are created.

Revision 1 calculates new decay heat values and the required decay time based on the revised final shutdown date at Oyster Creek, which will no longer have a Cycle 27 such that Cycle 26 becomes the final and bounding reload. Furthermore, the masses of assembly hardware pieces such as the channel box and tie plates are credited, which reduces the required decay time. This revision replaces all pages in the calculation.

Additional comment from ORIGEN Program SME Greg Heasley:
The method used in Attachment 2 to determine the decay heat used the bundle spec power. It was determined a Cycle 26 3rd burned bundle with higher power and exposure will produce approximately a 6% higher decay heat at 1 year. Due to the following conservatisms in the calculation, the zirc fire analysis performed herein is bounding: (1) No credit is taken for decay time between cycles, (2) stainless steel and lnconel in bundles are assumed to be Zirc-2, which has a considerably (>50%) lower specific heat, (3) conservatively assuming the pool starts at 125&deg;F instead of 86&deg;F (Section 5.6), and (4) conservatively not crediting the SFP rack material (Assumption 3.6) which has been demonstrated to reduce the cooling time by up to 50% in NRC-2015-0070-0224.

C-1302-226-E310-457 Rev. 1 Page 6 of41 The purpose of this calculation is to conservatively evaluate the length of time it takes for an uncovered spent fuel assembly in the spent fuel pool to reach the temperature where the zirconium cladding would fail. This analysis supports decommissioning of Oyster Creek Nuclear Generating Station (OCNGS).
The purpose of this calculation is to conservatively evaluate the length of time it takes for an uncovered spent fuel assembly in the spent fuel pool to reach the temperature where the zirconium cladding would fail. This analysis supports decommissioning of Oyster Creek Nuclear Generating Station (OCNGS).
Specifically, this analysis will be used to reduce the emergency planning staff once the hottest fuel assembly decay time is sufficient and is demonstrated to reach 900&deg;C in 10 hours which supports the requirements of ISG-02, Section 5, Item 2 (Ref. 9).

The number of hours it takes for the fuel to heat up (the heat-up time) is determined as a function of the decay time after shutdown. The heat load from GNF2 fuel used in this analysis is determined in Attachment 2. Note, the heat load was previously taken from Attachment 8 of Reference 1 in Revision 0 of this calculation.

2.0 Acceptance Criteria There are no specific acceptance criteria for this analysis; however, SECY-99-168 (Ref. 8) suggests that "10 hours (is) sufficient time to take mitigative action" and that for BWRs, 2 years is expected to be the decay time needed to reach a 10 hour heat-up time from 30 &deg;C to 900 &deg;C. NUREG-1738 shows that a 10 hour heat up time for a BWR requires less than 2 years of cooling time (Ref. 7, Fig. 2-1).

NUREG-1738 shows that a 10 hour heat up time for a BWR requires less than 2 years of cooling time (Ref. 7, Fig. 2-1).
NUREG/CR-6451 (Ref. 6) presents several studies discussing the maximum allowable temperature of zirconium cladding that will ensure that failure of the zirconium cladding will not occur. NUREG/CR-6451 states 565 &deg;C (1049 "F) is the lowest temperature where incipient cladding failure might occur. Per NUREG-1738 (Ref. 7, pg. 3-7), 900&deg;C (1652 &deg;F) is the temperature where "runaway oxidation" (zirconium fire) is expected to occur. Therefore, the decay period to reach a 10 hour heat-up time from 30         *c (86 &deg;F) to 900

3.2 Additional hardware materials made of stainless steel and lnconel X-750 are assumed to be zircaloy-2. This assumption is conservative since the specific heat capacity of zircaloy-2 is less than that of both stainless steel and lnconel X-750. For instance, at 300K (-70"F) the specific heat of zircaloy-2 is 0.28x103 J/kg*K (Reference 4), stainless steel is 0.50x10 3 J/kg*K (Reference 4), and

3.4 The specific heat for uranium dioxide and the zircaloy-2 cladding are determined at a temperature of 500&deg;F. A temperature of 500 "Fis in the temperature range (approximately the midpoint of both ranges) for this analysis. From Reference 4, the specific heat slightly increases with an increase in temperatures; at higher temperatures, the uranium dioxide and zircaloy-2 would heat up more slowly. Thus, using a temperature at the midpoint for material properties is conservative with respect to the assembly heat-up. This temperature is used as representative of the full temperature range in this analysis.

This was conservatively calculated by interpolating between the nine month (0.75 year) and one year times. This aligns with the 10 month decay time for Emergency Planning Level 1 determined in NRC-2015-0070 (Ref. 17).

Using the same 560 assemblies in the core, power level of 1930 MWt, and GNF2 fuel from Reference 1, the new bounding bundle power level is calculated below:

assembly This results in a total irradiation period calculated as 48762.3MWd Irradiation Period=           ~~   = 2566.11 days 19.0024 MTU These values are used to update the ORIG EN-ARP decay heat model from Reference 1 and the revised input file is included in Attachment 6 of this calculation. Table A8-2 from Attachment 8 of Reference 1 is recreated below using this Cycle 26 fuel information and accounts for the additional assembly hardware mass.

90 0.}8 f f Decay Heat Calculation C-1302-226-E310-457 Rev. 1 Page 17of41 The revised decay heat run is based on the Cycle 26 maximum burnup (48762.3 MWd/MTU), minimum enrichment (3.43%), and maximum MTU (0.181368 MTU/Assy) from Reference 12. Using the same 560 assemblies in the core, power level of 1930 MWt, and GNF2 fuel from Reference 1, the new bounding bundle power level is calculated below:
1 core 1
Bounding Avg. Power Level = 1930 MWt x 560 bl.

~~ = 2566.11 days 19.0024 MTU These values are used to update the ORIG EN-ARP decay heat model from Reference 1 and the revised input file is included in Attachment 6 of this calculation. Table A8-2 from Attachment 8 of Reference 1 is recreated below using this Cycle 26 fuel information and accounts for the additional assembly hardware mass. This also includes a 9-month (0.75 year) time step due to the increased margin from using this cycle.

Atlachment4 C-1302-226-E310-457 Rev. 1 SPECIA1 MEfA1S www.specialmetals.com JNCONEL alloy X-750 (UNS N07750/W. Nr. 2.4669) is a precipitation-hardenable nickel-chromium alloy used for its corrosion and oxidation resistance and high strength at temperatures to I 300&deg;F. Although much of the effect of precipitation hardening is lost with increasing temperature over J 300&deg;F, heat-treated material has useful strength up to J 800&deg;F. Alloy X-750 also has excellent properties down to cryogenic termperatures. Composition is shown in Table I.
The economics of INCONEL alloy X-750 coupled with its availability in all standard mill forms has resulted in applications in a wide variety of industrial fields. Jn gas turbines, it is used for rotor blades and wheels, bolts, and other structural members. INCONEL alloy X-750 is used extensively in rocket-engine thrust chambers. Airframe applications include thrust reversers and hot-air ducting systems. Large pressure vessels are formed from INCONEL alloy X-750. Other applications are heat-treating fixtures, forming tools, extrusion dies, and test machine grips. For springs and fasteners, INCONEL alloy X-750 is used from sub-zero to 1200&deg;F.
Depending on the application and the properties desired, various heat treatments are employed. For service above 1100&deg;F, particularly where loads are to be sustained for long times, optimum properties are achieved by solution treating (2100&deg;F) plus stabilization treating ( J 550&deg;F) plus precipitation treating ( 1300&deg;F}.
For service below 1100&deg;F, the alloy may be strengthened by precipitation treating after hot or cold working or by precipitation treating after equalizing or solution treating. A furnace-cooling treatment is also used to develop optimum properties for some applications.
The various heat treatments and the properties developed are described under the section on Mechanical Properties.
Property values in this bulletin - the results of extensive testing - are typical of the alloy but, unless shown as limiting, should not be used as specification values.

* Poisson's ratio = 0.29 Mechanical Properties INCONEL alloy X-750 may be given any one of a variety of heat treatments . Each develops special properties and puts the product form in the best condition for its intended application. In all conditions, alloy X-750 is resistant to oxidation up to 1800&deg;F. The most often used heat treatments have been incorporated by the Society of Automotive Engineers in their AMS specifications* for various product forms. The heat treatments, specifications, and product forms are summarized in Table 6.

"Certification of Permanent Cessation of Power Operations for Oyster Creek Nuclear Generating Station," dated February 14, 2018 (ML18045A084)

Pursuant to 1 O CFR 50.90, "Application for amendment of license or construction permit,"

Exelon Generation Company, LLC (Exelon) requests an amendment to Renewed Facility Operating License Number DPR-16 for Oyster Creek Nuclear Generating Station (OCNGS).

The proposed amendment would revise the effective and implementation dates of License Amendment No. 294, Permanently Defueled Emergency Plan (PDEP) and Emergency Action Level (EAL) scheme for the permanently defueled condition. The proposed changes are being submitted to the U.S. Nuclear Regulatory Commission (NRC) for approval prior to implementation.

On September 17, 2018, OCNGS permanently ceased power operations (Reference 1). By letter dated September 25, 2018, (Reference 2), Exelon certified that all fuel had been permanently removed from the OCNGS reactor vessel and placed in the spent fuel pool (SFP).

On October 17, 2018, the NRC approved License Amendment No. 294, OCNGS PDEP and Permanently Defueled EAL Scheme (Reference 3). The PDEP and Permanently Defueled EAL scheme were predicated on approval of requests for Exemptions from portions of 1 O CFR 50.47(b), 1 O CFR 50.47(c)(2), and 1 O CFR Part 50, Appendix E,Section IV, which were approved on October 16, 2018 (Reference 4).

The PDEP and Permanently Defueled EAL scheme were predicated on approval of requests for exemptions from portions of 1 O CFR 50.47(b), 10 CFR 50.47(c)(2), and 10 CFR Part 50, Appendix E, Section IV, approved in Reference 4. The PDEP reduces the scope of offsite and onsite emergency planning commensurate with the permanently defueled condition.

The basis for the approval of the exemptions from offsite emergency preparedness (EP) requirements included a site-specific analysis that showed that the fuel stored in the SFP would not reach the zirconium ignition temperature in fewer than 1 O hours from the time at which it was assumed a loss of both water and air cooling of the spent fuel (zirc-fire window). Exelon's site-specific analyses for OCNGS, as provided in Exelon's exemption request (Reference 5),

showed that 12 months after permanent cessation of power operations, the spent fuel stored in the SFP will have decayed to the extent that the requested exemptions may be implemented at OCNGS.

Since the time of the submittal of the original adiabatic calculation in Reference 5, two key assumptions have been reconsidered based on actual conditions at the time of final shutdown.

First, the fuel in the reactor at the time of the final shutdown (Cycle 26) was considered instead of projected next cycle fuel (Cycle 27). As provided in Reference 6, the conditions through the end of Cycle 26 result in less decay heat in its limiting bundle than the limiting bundle used from Cycle 27. Second, the masses of fuel bundle assembly hardware pieces, such as the channel box and tie plates are credited, which reduces the required decay time.

U.S. Nuclear Regulatory Commission License Amendment Request Docket Nos. 50-219 and 72-15 October 22, 2018 Page 3 The revised adiabatic calculation provided in Attachment 2, factoring in these reconsidered assumptions, validates the response in Reference 6 and results in a reduced decay period of 9.38 months (285 days} for the zirc-fire window after the final reactor shut down. Significant conservatisms remain in the calculation.

Exelon is requesting that License Amendment No 294 (Reference 3} become effective 9.38 months (285 days} from the date of the permanent shut down of OCNGS on September 17, 2018 (Reference 1 }, as stated in the certification that OCNGS has been permanently shut down and defueled (Reference 2), which revises the amendment effective date to June 29, 2019.

License Amendment No. 294 is to become effective 12 months (365 days} following the permanent cessation of power operations and shall be implemented within 60 days of the effective date, but no later than March 28, 2021.

The description, technical and regulatory evaluation, significant hazards determination, and environmental considerations evaluation for the proposed amendment are contained in the. The revised bounding analysis is provided in Attachment 2.

The proposed change of the effective date for the PDEP and Permanently Defueled EAL scheme does not impact or change anything within the approved PDEP (Reference 3} other than the effective and implementation dates.

Exelon requests approval of the proposed license amendment by May 1, 2019, and an effective date of June 29, 2019. Exelon will implement this LAR within 30 days from the effective date; but no later than July 31, 2019. Approval by May 1, 2019, will provide Exelon the certainty in implementing change management for a significant reduction in site staffing.

The proposed change has been reviewed and approved by the station's Safety Review Committee in accordance with the requirements of the Exelon Decommissioning Quality Assurance Program.

In support of this license amendment request, Exelon has discussed the proposed change regarding the earlier implementation of the PDEP and Permanently Defueled EAL scheme with the New Jersey Bureau of Nuclear Engineering and local response organizations.

The proposed change has been evaluated in accordance with 10CFR50.91 (a}(1} using criteria in 1 O CFR 50.92(c}, and Exelon has determined that this change involves no significant hazards consideration. Exelon has also determined that the proposed change satisfies the criteria for categorical exclusion in accordance with 1 O CFR 51.22(c}(9} and does not require an environmental review. Therefore, pursuant to 1 O CFR 51.22(b}, no environmental impact statement or environmental assessment is required.

No commitments to the NRC are made in this letter.

SUMMARY

DESCRIPTION Page 1 of 6 Pursuant to 1 O CFR 50.90, "Application for amendment of license or construction permit, "Exelon Generation Company, LLC (Exelon) requests an amendment to Renewed Facility Operating License Number DPR-16 for Oyster Creek Nuclear Generating Station (OCNGS). The proposed amendment would revise the effective and implementation dates of License Amendment No. 294, Permanently Defueled Emergency Plan (PDEP), Emergency Action Level (EAL) scheme for the permanently defueled condition, and associated Exemption from portions of 1 O CFR 50.47(b),

1 O CFR 50.47(c)(2), and 1 O CFR Part 50, Appendix E,Section IV. The proposed changes are being submitted to the U.S. Nuclear Regulatory Commission (NRG) for approval prior to implementation.

The proposed change of the effective date for the PDEP, Permanently Defueled EAL scheme, and associated exemptions does not impact or change anything within the approved PDEP (Reference 5) or exemptions (Reference 6) other than the effective and implementation dates.

2.0 BACKGROUND

On January 7, 2011, Exelon informed the NRG that OCNGS will permanently cease power operations by December 31, 2019 (Reference 1 ). On February 2, 2018, Exelon announced that it planned to retire OCNGS no later than October 31, 2018 at the end of the current two-year operating cycle. Exelon informed the NRG of this change in Reference 2.

On September 17, 2018, OCNGS permanently ceased power operations (Reference 3). By letter dated September 25, 2018, (Reference 4), Exelon certified that all fuel had been permanently removed from the OCNGS reactor vessel and placed in the spent fuel pool (SFP).

On October 17, 2018, the NRG approved License Amendment No. 294, OCNGS PDEP and Permanently Defueled EAL Scheme (Reference 5). The PDEP and Permanently Defueled EAL scheme were predicated on approval of requests for Exemptions from portions of 10 CFR 50.47(b), 1 O CFR 50.47(c)(2), and 1 O CFR Part 50, Appendix E,Section IV, which were approved on October 16, 2018 (Reference 7).

License Amendment No. 294 becomes effective 12 months (365 days) following the permanent cessation of power operations and shall be implemented within 60 days of the effective date, but no later than March 28, 2021.

3.0 BASIS FOR PROPOSED CHANGES The basis for the approval of the exemptions from offsite emergency preparedness (EP) requirements included a site-specific analysis that showed that the fuel stored in the SFP would not reach the zirconium ignition temperature in fewer than 1 O hours from the time at which it was assumed a loss of both water and air cooling of the spent fuel. Exelon's site-specific analyses for OCNGS, as provided in Exelon's exemption request (Reference 7), showed that 12 months after permanent cessation of power operations, the spent fuel stored in the SFP will have decayed to the extent that the requested exemptions may be implemented at OCNGS.

Since the time of the submittal of the original adiabatic calculation in Reference 7, two key assumptions have been reconsidered based on actual conditions at the time of final shutdown.

First, the fuel in the reactor at the time of the final shutdown (Cycle 26) was considered instead of projected next cycle fuel (Cycle 27). When the original calculation was submitted, OCNGS was

License Amendment Request Permanently Defueled Emergency Plan Proposed Effective and Implementation Dates Change Page 2 of 6 scheduled to shut down no later than the end of December 2019 (Reference 1) and a refueling outage in October 2018 was scheduled to load fuel for Cycle 27. However, Exelon decided to reschedule the final shutdown to no later than October 31, 2018 (Reference 2), at the end of the current two-year operating cycle (Cycle 26). A revised adiabatic calculation (provided in ) was performed that calculates new decay heat values and the required decay time based on the revised final shutdown date at OCNGS, which no longer includes Cycle 27, such that, Cycle 26 becomes the final and bounding reload.

Second, the masses of fuel bundle assembly hardware pieces, such as the channel box and tie plates are credited, which reduces the required decay time. The revised adiabatic calculation (provided in Attachment 2) factors in the reconsidered assumptions and the results indicate that the 12-month decay period originally predicted in Reference 7 may be reduced to 9.38 months (285 days) after the final reactor shut down.

Significant conservatisms remain in the calculation such as:

Adiabatic heat up of the fuel bundle is utilized thus not accounting for the actual heat losses that would occur due to radiative and convective heat transfer to surrounding structures.

The calculation assumed power level was at 100% up to when shutdown occurred.

Reactor power level was 70% for 51 days prior to final shutdown. The reduced power level results in a reduction in the starting decay heat that would be present in the actual hottest fuel bundle.

The specific heat for fuel assembly hardware pieces (stainless steel or lnconel) were assumed to be the lower specific heat of zircalloy. Actual fuel heat-up would be slower with actual materials.

Starting temperature of the spent fuel pool was assumed to be 125°F instead of normal pool temperatures of less than 115°F. Lower temperature adds additional time to fuel heat-up.

The revised decay time is consistent with NRC's stated generic time for Boiling Water Reactors (BWRs) as documented in NUREG/CR-6451 BNL-NUREG-52498, "A Safety and Regulatory Assessment of Generic BWR and PWR [Pressurized Water Reactor] Permanently Shutdown Nuclear Power Plants" (Reference 8) and the Regulatory Basis document for "Regulatory Improvements for Power Reactors Transitioning to Decommissioning" (Reference 9). Oyster Creek is a lower power density plant than the BWR referenced in above documents; therefore, OCNGS would be expected to have a site-specific calculation that would be less than the generic required decay time.

Therefore, Exelon is requesting that the License Amendment No. 294 (Reference 5) become effective 9.38 months (285 days) from the date of the permanent shut down of OCNGS on September 17, 2018, as stated in the certification that OCNGS has been permanently shut down and defueled (Reference 4), which revises the amendment effective date to June 29, 2019.

4.0 TECHNICAL EVALUATION

As discussed above, based on actual conditions at the time of final shutdown, Exelon has revised the site-specific analysis that showed that the fuel stored in the SFP would not reach the zirconium ignition temperature in fewer than 1 O hours from the time at which it was assumed a loss of both water and air cooling of the spent fuel based on reconsideration of two key assumptions. The

5.0 REGULATORY EVALUATION

5.1 Applicable Regulatory Requirements and Guidance Exelon intends to meet the applicable emergency regulatory requirements with the Exemptions approved in Reference 6 and license provisions approved in License Amendment No. 294 (Reference 5).

5.2 Precedent The proposed change revises the effective and implementation dates of License Amendment No.

294, OCNGS PDEP, Permanently Defueled EAL scheme (Reference 5), and Exemptions from portions of 1 O CFR 50.47 and 1 O CFR Part 50, Appendix E (Reference 6). Three similarly related license amendments involving changes to license amendment implementation due dates were approved in 2015 and 2004, and are listed below:

1. Limerick Generating Station, Unit 2 - Issuance of Exigent Amendment RE: Extend Implementation Period for Amendment No. 174-Leak Detection System Setpoint and Allowable Value Changes (TAC NO.

MF5695),

dated February 25, 2015 (ML 150049A084).

2. Sequoyah Nuclear Plant Unit 1 (SON) - Issuance of Emergency Amendment to Extend Implementation Period for License Amendment No. 294 (TAC NO. MC5041 ), dated November 9, 2004 (ML043130006).
3. Fort Calhoun Station, Unit No.1 - Issuance of Amendment (TAC No. MC1949), dated February 13, 2004 (ML040490383).

5.3 No Significant Hazards Consideration Determination The proposed change would revise the effective and implementation dates of License Amendment No. 294, Oyster Creek Nuclear Generating Station (OCNGS) Permanently Defueled Emergency Plan (PDEP) and Emergency Action Level (EAL) scheme (Reference 5)

[ML18221A400] and Exemptions from portions of 10 CFR 50.47 and 10 CFR Part 50, Appendix E (Reference 6) [ML 182220A980]. Implementation of the previously approved PDEP, Permanently Shutdown EALs, and associated Exemptions are predicated on a site-specific analysis that showed that the fuel stored in the spent fuel pool (SFP) would not reach the zirconium ignition temperature in fewer than 1 O hours from the time at which it was assumed a loss of both water and air cooling of the spent fuel at 12 months after the reactor had been shut down (zirc-fire window). The site-specific analysis has been revised to take into consideration actual conditions at the time of permanent shutdown that impact two key assumptions used in the original analysis. The revised site-specific analysis showed that the zirc-fire window may be revised to 9.38 months (285 days) after the reactor had been shutdown.

Pursuant to 1 o CFR 50.92, Exelon has reviewed the proposed changes and concludes that the changes do not involve a significant hazards consideration because the proposed changes satisfy the criteria in 1 O CFR 50.92(c). These criteria require that operation of the facility in accordance with the proposed amendment would not (1) involve a significant increase in the probability or consequences of an accident previously evaluated; (2) create the possibility of a new or different

License Amendment Request Permanently Defueled Emergency Plan Proposed Effective and Implementation Dates Change Page 4 of 6 kind of accident from any accident previously evaluated; or (3) involve a significant reduction in a margin of safety.

The discussion below addresses each of these criteria and demonstrates that the proposed amendment does not constitute a significant hazard.

1.

Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?

Response: No The proposed change to the effective and implementation dates of License Amendment No. 294, OCNGS PDEP, Permanently Shutdown EAL scheme, and associated Exemptions at 9.38 months (285 days) does not impact the function of plant structures, systems, or components (SSCs). The proposed change does not affect accident initiators or precursors, nor does it alter design assumptions. The proposed change does not prevent the ability of the on-shift staff and emergency response organization (ERO) to perform their intended functions to mitigate the consequences of any accident or event that will be credible in the permanently defueled condition.

The probability of occurrence of previously evaluated accidents is not increased, since most previously analyzed accidents can no longer occur and the probability of the few remaining credible accidents are unaffected by the proposed amendment.

Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

2.

Does the proposed amendment create the possibility of a new or different kind of accident from any accident previously evaluated?

Response: No The proposed change to effective and implementation dates for License Amendment No.

294, PDEP, Permanently Shutdown EAL scheme, and associated Exemptions at 9.38 months (285 days) is commensurate with the hazards associated with a permanently shutdown and defueled facility based on the updated site-specific analysis that showed the fuel stored in the SFP would not reach the zirconium ignition temperature in fewer than 1 O hours from the time at which it was assumed a loss of both water and air cooling of the spent fuel. The proposed change does not involve installation of new equipment or modification of existing equipment, so that no new equipment failure modes are introduced. In addition, the proposed change does not result in a change to the way that the equipment or facility is operated so that no new or different kinds of accident initiators are created.

Therefore, the proposed change does not create the possibility of a new or different kind of accident from any previously evaluated.

3.

Does the proposed amendment involve a significant reduction in a margin of safety?

Response: No Margin of safety is associated with confidence in the ability of the fission product barriers (i.e., fuel cladding, reactor coolant system pressure boundary, and containment structure)

License Amendment Request Permanently Defueled Emergency Plan Proposed Effective and Implementation Dates Change Page 5 of 6 to limit the level of radiation dose to the public. The proposed change is associated with changing the effective and implementation dates of License Amendment No. 294, PDEP, Permanently Shutdown EAL scheme and associated Exemptions; it does not impact operation of the plant or its response to transients or accidents. The change does not affect the Technical Specifications. The proposed change does not involve a change in the method of plant operation, and no design bases accident analyses will be affected by the proposed changes. Safety analysis acceptance criteria are not affected by the proposed changes. The PDEP will continue to provide the necessary response staff with the appropriate guidance to protect the health and safety of the public.

Therefore, the proposed change does not involve a significant reduction in a margin of safety.

Based on the above, Exelon concludes that the proposed change presents no significant hazards consideration under the standards set forth in 1 O CFR 50.92{c), and, accordingly, a finding of "no significant hazards consideration" is justified.

5.4 Conclusion In conclusion, based on the considerations discussed above: 1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, 2) such activities will be conducted in compliance with 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.

6.0 ENVIRONMENTAL CONSIDERATION

S This amendment request meets the eligibility criteria for categorical exclusion from environmental review set forth in 1 O CFR 51.22(c)(9) as follows:

(i)

The amendment involves no significant hazards consideration.

As described in Section 5.3 of this evaluation, the proposed changes involve no significant hazards consideration.

(ii)

There is no significant change in the types or significant increase in the amounts of any effluent that may be released offsite.

The proposed changes do not involve any physical alterations to the plant configuration or any changes to the operation of the facility that could lead to a change in the type or amount of effluent release offsite.

(iii) There is no significant increase in individual or cumulative occupational radiation exposure.

The proposed changes do not involve any physical alterations to the plant configuration or any changes to the operation of the facility that could lead to a significant increase in individual or cumulative occupational radiation exposure.

Based on the above, Exelon concludes that the proposed change meets the eligibility criteria for categorical exclusion as set forth in 10 CFR 51.22{c)(9). Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of this amendment.

Exelon Reviewer Comments:

An HU-AA-1212 pre-job brief for owner's acceptance was held on 3/15/17 with the DEM and Exelon acceptance reviewer. The overall risk ranking was a '1,' therefore, existing in-process reviews are sufficient. An ITPR is not required. The brief did identify that additional technical expertise was required as allowed by CC-AA-103-1003 in the form of a review committee. Technical experts in Nuclear Fuels (Jill Fisher), Reactor Engineering (Jim Frank), Oyster Creek Emergency Plan (Jim Frank), and ORIG EN program SME (Greg Heasley) were utilized to support the Exelon owner's acceptance review. The Exelon acceptance reviewer (Robert Csillag) acted as chair of this committee and coordinated all Exelon reviews performed per CC-AA-103-1003, Attachment 2 and resolution of all comments.

LJ Enercon was verified to be on the approved vendor list as an EOC per CC-AA-12, Attachment 1, therefore, a design review by Exelon is not required. Design qualifications were verified to be current for the Exelon owner's acceptance reviewer as was verification of being part of the ESP population.

Critical inputs and assumptions were scrutinized as was the veracity of the conclusions. Comments were supplied by the Exelon owner review committee. All comments were resolved to the satisfaction of the Exelon owner's review committee by the EOC.

Additional comment from ORIGEN Program SME Greg Heasley:

The method used in Attachment 2 to determine the decay heat used the bundle spec power. It was determined a Cycle 26 3rd burned bundle with higher power and exposure will produce approximately a 6% higher decay heat at 1 year. Due to the following conservatisms in the calculation, the zirc fire analysis performed herein is bounding: (1) No credit is taken for decay time between cycles, (2) stainless steel and lnconel in bundles are assumed to be Zirc-2, which has a considerably (>50%) lower specific heat, (3) conservatively assuming the pool starts at 125°F instead of 86°F (Section 5.6), and (4) conservatively not crediting the SFP rack material (Assumption 3.6) which has been demonstrated to reduce the cooling time by up to 50% in NRC-2015-0070-0224.

1.0 Purpose and Scope

C-1302-226-E310-457 Rev. 1 Page 6 of41 The purpose of this calculation is to conservatively evaluate the length of time it takes for an uncovered spent fuel assembly in the spent fuel pool to reach the temperature where the zirconium cladding would fail. This analysis supports decommissioning of Oyster Creek Nuclear Generating Station (OCNGS).

Specifically, this analysis will be used to reduce the emergency planning staff once the hottest fuel assembly decay time is sufficient and is demonstrated to reach 900°C in 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> which supports the requirements of ISG-02, Section 5, Item 2 (Ref. 9).

The number of hours it takes for the fuel to heat up (the heat-up time) is determined as a function of the decay time after shutdown. The heat load from GNF2 fuel used in this analysis is determined in. Note, the heat load was previously taken from Attachment 8 of Reference 1 in Revision 0 of this calculation.

2.0 Acceptance Criteria There are no specific acceptance criteria for this analysis; however, SECY-99-168 (Ref. 8) suggests that "10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> (is) sufficient time to take mitigative action" and that for BWRs, 2 years is expected to be the decay time needed to reach a 10 hour1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> heat-up time from 30 °C to 900 °C. NUREG-1738 shows that a 10 hour1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> heat up time for a BWR requires less than 2 years of cooling time (Ref. 7, Fig. 2-1).

NUREG/CR-6451 (Ref. 6) presents several studies discussing the maximum allowable temperature of zirconium cladding that will ensure that failure of the zirconium cladding will not occur. NUREG/CR-6451 states 565 °C (1049 "F) is the lowest temperature where incipient cladding failure might occur. Per NUREG-1738 (Ref. 7, pg. 3-7), 900°C (1652 °F) is the temperature where "runaway oxidation" (zirconium fire) is expected to occur. Therefore, the decay period to reach a 10 hour1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> heat-up time from 30 *c (86 °F) to 900

°C is used as the acceptance criteria in this calculation. The decay period to reach a 10 hour1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> heat-up time from 30 *c to 565 *c is also presented to show when cladding failure may occur.

NRC-2015-0070, Appendix A, Section 4.2.6 (Ref. 17) states that for BWRs a 10 month period for Level 1 (post-shutdown emergency planning) shall be used unless a site-specific analysis demonstrates a shorter time period is acceptable for reaching a cladding temperature of 900 °C within 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br />.

3.0 Assumptions 3.1 The heat-up time is conservatively assumed to start when the spent fuel pool has been completely drained. This is conservative as the drain down time would increase the time to cladding failure.

3.2 Additional hardware materials made of stainless steel and lnconel X-750 are assumed to be zircaloy-2. This assumption is conservative since the specific heat capacity of zircaloy-2 is less than that of both stainless steel and lnconel X-750. For instance, at 300K (-70"F) the specific heat of zircaloy-2 is 0.28x103 J/kg*K (Reference 4), stainless steel is 0.50x103 J/kg*K (Reference 4), and

C-1302-226-E310-457 Rev. 1 Page 7 of 41 lnconel X-750 is 0.43x103 J/kg*K (0.103 Btu/lb*"F) (Reference 14). A lower specific heat capacity is conservative because it results in a shorter heat-up time.

3.3 OCNGS final cycle 26 will contain a full core of GNF2 fuel (Ref. 12); therefore, the analysis herein will only evaluate the heat up of GNF2 fuel assemblies and not any other assembly type in the spent fuel pool because the offloaded fuel directly after a cycle contains the assemblies with the highest decay heat (referred to as the hottest fuel assembly here-in).

3.4 The specific heat for uranium dioxide and the zircaloy-2 cladding are determined at a temperature of 500°F. A temperature of 500 "Fis in the temperature range (approximately the midpoint of both ranges) for this analysis. From Reference 4, the specific heat slightly increases with an increase in temperatures; at higher temperatures, the uranium dioxide and zircaloy-2 would heat up more slowly. Thus, using a temperature at the midpoint for material properties is conservative with respect to the assembly heat-up. This temperature is used as representative of the full temperature range in this analysis.

3.5 This analysis conservatively assumes that there is no air cooling of the assemblies (i.e., adiabatic conditions): the flow paths that would provide natural circulation cooling are assumed to be blocked.

3.6 The fuel assembly material is assumed to start at a uniform temperature and heat up at uniform rate. While there are temperature gradients throughout the assemblies, these are small relative to the total heat up from 125 "F (Input 5.6) to either 1049 "F for cladding failure or 1652 "F for zirconium fire. Furthermore, this simplified approach is still conservative overall since convective and radiative heat transfer are not considered, nor is conduction to other structural materials such as the SFP racks.

3.7 Gadolinium, which is a burnable poison and can be used in some fuel rods (Reference 2), is conservatively not included in this evaluation.

5.0 Input Data 5.1 Zirconium Properties The cladding for the GNF2 fuel is zircaloy-2 (Ref. 5). The specific heat of zircaloy-2 at 500°F (533 K)

(Assumption 3.4) is 0.0761 Btu/ lbm-°F (Ref. 5, p. 89) and the density of zircaloy-2 is 6.56 g/cm3 (409.53 lb/ft3) (Ref. 10). The GNF2 channel is also zirconium alloy (Reference 15).

5.2 Uranium Properties The specific heat of uranium dioxide at 500 °F (533 K) (Assumption 3.4) is 0.0683 Btu/ lbm-°F (Ref. 5, p. 89) and the density of uranium dioxide is 10.6 g/cm3 (661.74 lb/ ft3) (Ref. 5, p. 19).

5.3 Geometry for Limiting Assemblies The table below shows the geometry inputs for the fuel assemblies used in this analysis. OCNGS's final cycle before decommissioning will contain a full core of GNF2 fuel (Assumption 3.3); therefore, the analysis herein will only evaluate the heat up of GNF2 fuel assemblies and not any other assembly type in the spent fuel pool because the offloaded fuel directly after a cycle is the hottest fuel assemblies in the pool. Table 1 contains fuel assembly input data for GNF2 fuel.

Total 28.35 Modeled as Zircaloy-2 per Assumption 3.2 5.5 Heat Load determines the maximum heat load from a single fuel assembly, based on the information provided in Attachment 3. The assembly with the highest heat load will have the shortest heat-up time.

The table showing the maximum fuel assembly heat generation rates for several years is in Attachment 2, Table A2-l.

The worst-case (hottest) bundle is one that was discharged at the end of Cycle 26 and has been cooling for nine months.

From Table A2-1, it has a heat load of 1.091xl04 W/MTU. The maximum 0.181368 MTU/assembly value was derived from Cycle 26 data (Reference 12). The worst-case heat per assembly is calculated as follows:

= 6752 BTU /hr assembly The worst-case bundle heat load is determined at the remaining decay times (1 year, 1.25 years, 1.5 years, etc) using the same methodology.

5.6 Water Temperature The starting temperature for the heat-up analysis is taken as a uniform 125 °F (51 °C). The temperature of 125 °F (51 °C) is the maximum initial pool temperature at or near the surface (Ref. 3). SECY-99-168 (Ref. 8) and NUREG-1738 (Ref. 7) both set the starting water temperature at 30 °C (86 °F), so setting the initial temperature to the maximum pool temperature is conservative.

6.0 Identification of Computer Codes The ORIGEN-ARP module of the SCALE 6.1 code package is used to calculate new decay heat values in of this calculation. This revised model is based on the existing ORIGEN-ARP models developed as part of C-1302-226-E310-458 (Reference 1). Further discussion on the use and application of this software is contained within C-1302-226-E310-458.

7.0 Method of Analysis This analysis determines the heat-up time of the fuel assembly using the thermal capacity of materials.

As discussed in Assumption 3.6, this simplified approach is both reasonable and conservative given the overall temperature range and not accounting for convective or radiative heat transfer in the analysis.

Equation 7-1(Ref.11, Ch. 8):

Where:

!ff cj = m X Cp X-t m = pxV cj is the heat generation rate in BTU/hr mis the mass of material in lb p is the density of the material in lb/ft3 V is the volume of the material in ft3 Cp is the specific heat in BTU/lb- °F llT is the temperature increase in °F t is the heat-up time in hr

C-1302-226-E310-457 Rev. 1 Page 11 of41 For this analysis, there are two materials that are considered: the uranium dioxide fuel pellets and zircaloy-2. Zircaloy-2 comprises the cladding, the water tubes, channel, and the additional hardware (Assumption 3.2), all of which are also being heated. Under adiabatic conditions, zircaloy-2 and the uranium dioxide are modeled as heating up at the same rate, so the ti.; will be the same for both materials.

Equation 7-2:

Where:

tlT q = t x (Pu x Vu x Cp,u + Pz x 11z x Cp,z + mz x Cp,z)

Xu signifies the property is for uranium dioxide Xz signifies the property is for zirconium mz signifies any additional hardware modeled as zirconium This calculation seeks the heat-up time, so Equation 7-2 is solved fort.

The length ofthe cladding, water rods, and channel that are heated are conservatively modeled as being the same as the heated length of uranium dioxide. In reality, they are longer than the length ofthe uranium dioxide pellets.

C-1302-226-E310-457 Rev. 1 Page 13 of 41 The temperature increase (~T) for this analysis is taken to be from the initial temperature of the pool, 125"F (51 *q (Input 5.6), to the zirconium cladding failure temperatures of interest, 1049"F (565°C) and 1652"F (900°C) (Acceptance Criteria, Section 2).

The heat-up time is calculated as a function of the decay time for each of the times in Attachment 2. The hottest assembly source term methodology is described in Attachment 2.

The heat-up time to 1049°F for the nine-month decay maximum bundle (Section 5.5) is shown below; the heat-up for the remaining decay times is solved in the same exact manner (i.e., changing the heat load and keeping the remaining inputs constant) and the results are reported in Section 9.

This was conservatively calculated by interpolating between the nine month (0.75 year) and one year times. This aligns with the 10 month decay time for Emergency Planning Level 1 determined in NRC-2015-0070 (Ref. 17).

Using the same 560 assemblies in the core, power level of 1930 MWt, and GNF2 fuel from Reference 1, the new bounding bundle power level is calculated below:

Table A8-2 from Attachment 8 of Reference 1 is recreated below using this Cycle 26 fuel information and accounts for the additional assembly hardware mass. This also includes a 9-month (0.75 year) time step due to the increased margin from using this cycle.

Purpose of Information:

Provides inputs to Enercon calculation for "Oyster Creek Nuclear Generating Station Zirconium Fire Analysis for Drained Soent Fuel Pool" assuming a shutdown date of October 151, 2018.

Description of Information/Basis:

This package provides information necessary to revise the "Oyster Creek Nuclear Generating Station Zirconium Fire Analysis for Drained Spent Fuel Pool" which was previously based on the final operating cycle 27 fuel data.

With Exelon decision to shut down Oyster Creek after cycle 26, the calculation is being revised to determine the potential reduction in acceptable decay time for the limiting bundle for the cycle 26 core. The information generated assumes a shutdown date of October 151, 2018.

Atlachment4 C-1302-226-E310-457 Rev. 1 SPECIA1 MEfA1S www.specialmetals.com JNCONEL alloy X-750 (UNS N07750/W. Nr. 2.4669) is a precipitation-hardenable nickel-chromium alloy used for its corrosion and oxidation resistance and high strength at temperatures to I 300°F. Although much of the effect of precipitation hardening is lost with increasing temperature over J 300°F, heat-treated material has useful strength up to J 800°F. Alloy X-750 also has excellent properties down to cryogenic termperatures. Composition is shown in Table I.

The economics of INCONEL alloy X-750 coupled with its availability in all standard mill forms has resulted in applications in a wide variety of industrial fields. Jn gas turbines, it is used for rotor blades and wheels, bolts, and other structural members. INCONEL alloy X-750 is used extensively in rocket-engine thrust chambers. Airframe applications include thrust reversers and hot-air ducting systems. Large pressure vessels are formed from INCONEL alloy X-750. Other applications are heat-treating fixtures, forming tools, extrusion dies, and test machine grips. For springs and fasteners, INCONEL alloy X-750 is used from sub-zero to 1200°F.

Depending on the application and the properties desired, various heat treatments are employed. For service above 1100°F, particularly where loads are to be sustained for long times, optimum properties are achieved by solution treating (2100°F) plus stabilization treating ( J 550°F) plus precipitation treating ( 1300°F}.

For service below 1100°F, the alloy may be strengthened by precipitation treating after hot or cold working or by precipitation treating after equalizing or solution treating. A furnace-cooling treatment is also used to develop optimum properties for some applications.

The various heat treatments and the properties developed are described under the section on Mechanical Properties.

Property values in this bulletin - the results of extensive testing - are typical of the alloy but, unless shown as limiting, should not be used as specification values.
