SUMMARY
DESCRIPTION This evaluation supports a FirstEnergy Nuclear Operating Company (FENOC) request to:
- Revise Technical Specification (TS) 3.7.3, "Control Room Emergency Recirculation (CRER) System," to change the runtime requirement from "10 continuous hours" to "15 continuous minutes," and to delete "with heaters operating" in Surveillance Requirement (SR) 3.7.3.1.
- Revise TS 3.6.4.3, "Annulus Exhaust Gas Treatment (AEGT) System," to change the runtime requirement from "10 continuous hours" to "15 continuous minutes," and to delete "with heaters operating" in SR 3.6.4.3.1 to align it with proposed changes to SR 3.7.3.1.
- Delete TS 3.7.8, "Fuel Handling Building," to align with the license basis.
- Delete TS 3.7.9, "Fuel Handling Building Ventilation Exhaust System," to align with the license basis.
- Revise TS 3.7.7, "Fuel Pool Water Level," to add a parenthetical note at the bottom of the page, which cites the next TS page number. This is necessary due to the deletion of TS pages associated with TS 3.7.8 and TS 3.7.9.
- Revise TS 3.6.1.3, "Primary Containment Isolation Valves," to increase the allowable secondary containment bypass leakage rate from 0.0504 La to 0.1008 La and align with the license basis.
- Revise TS 5.5.7, "Ventilation Filter Testing Program (VFTP)," to align with the license basis and other proposed changes to the TS.
- Revise the TS table of contents to delete two TS sections and to align the table of contents with changes associated with previously issued license amendments.
The proposed TS changes are marked in Attachment 1; the TS retyped pages incorporating the proposed changes are provided in Attachment 2. The planned TS Bases changes in Attachment 3 are provided for information only.
2.0 DETAILED DESCRIPTION On December 9, 2002, FENOC submitted a license amendment request supporting partial implementation of alternative source term (AST) for the Perry Nuclear Power Plant (PNPP). On March 4, 2003, NRC staff issued License Amendment No. 122, which established a license basis that included the following AST aspects for a design basis fuel handling accident (FHA):
- No credit taken for the fuel handling building exhaust system (FHBES).
- No credit taken for fuel handling building (FHB) integrity.
- A fission product decay period of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> (time period from the reactor shutdown to the first fuel movement).
The current PNPP TS for the FHB and the FHBES are applicable during the movement of recently irradiated fuel (irradiated fuel that has been subcritical < 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />). The current TS are not aligned with the license basis that was established with Amendment No. 122.
On December 6, 2013, FENOC submitted a license amendment request supporting full implementation of AST for the PNPP. On March 30, 2015, NRC staff issued License Amendment No. 166, which established a license basis that included the following AST aspects:
Page 3 of 13
- An increase in allowable secondary containment bypass leakage to 0.1008 La.
- Design basis loss of coolant accident (LOCA) credits an 80 percent removal efficiency of elemental iodine and organic iodide by the CRER system charcoal filters.
- None of the radiological consequence analyses credit any removal of elemental and organic iodines by the AEGT system charcoal filters.
The current PNPP TS allowable secondary containment bypass leakage criterion is >
0.0504 La. The current ventilation filter testing program TS is based on a 95 percent removal efficiency by the CRER system charcoal filters and credits removal of elemental iodine and organic iodides by the AEGT system charcoal filters. The current TS are not aligned with the license basis that was established with Amendment No. 166.
On September 20, 2012, the NRC approved Technical Specification Task Force (TSTF)
Traveler TSTF-522, which identified the following AEGT and CRER system surveillance enhancements:
- Licensees can revise AEGT and CRER system surveillance requirements to only require operation of the systems for 15 continuous minutes.
- Licensees can revise AEGT and CRER system surveillance requirements to delete "with heaters operating," if a 95 percent (%) relative humidity (RH) charcoal testing criterion is also adopted.
The current PNPP TS surveillance requirements for the AEGT and CRER systems require operation of the systems for 10 continuous hours with heaters operating.
FENOC proposes to revise the PNPP TS as follows.
2.1 SYSTEM RUNTIME AND HEATER OPERATION FENOC proposes to amend TS 3.7.3, "Control Room Emergency Recirculation (CRER)
System," by revising SR 3.7.3.1 to align with NUREG-1434, Revision 4, Volume 1, "Standard Technical Specifications - General Electric BWR/6 Plants," the NRC-approved Technical Specification Task Force (TSTF) Traveler 522, "Revise Ventilation System Surveillance Requirement to Operate for 10 Hours per Month," and RG 1.52, "Design, Inspection, and Testing Criteria for Air Filtration and Adsorption Units of Post-Accident Engineered-Safety-Feature Atmosphere Cleanup Systems in Light-Water-Cooled Nuclear Power Plants," Revision 4.
FENOC also proposes to amend TS 3.6.4.3, "Annulus Exhaust Gas Treatment (AEGT)
System," to align SR 3.6.4.3.1 with the changes proposed for SR 3.7.3.1.
2.1.1 Proposed Changes to SR 3.7.3.1 PNPP SR 3.7.3.1 currently requires operating each CRER subsystem for greater than or equal to (£) 10 continuous hours with the heaters operating in accordance with the Surveillance Frequency Control Program.
With the proposed change, PNPP SR 3.7.3.1 will read "Operate each CRER subsystem for > 15 continuous minutes." The requirement "with heaters operating" will also be deleted. There is no change to the frequency requirement, which remains, "In accordance with the Surveillance Frequency Control Program."
Page 4 of 13 2.1.2 Proposed Changes to SR 3.6.4.3 PNPP SR 3.6.4.3.1 currently requires operating each AEGT subsystem for > 10 continuous hours with the heaters operating.
The proposed amendment to PNPP TS 3.6.4.3, "Annulus Exhaust Gas Treatment (AEGT)
System," will align PNPP SR 3.6.4.3.1 to the changes proposed for SR 3.7.3.1.
With the proposed change, PNPP SR 3.6.4.3.1 will read "Operate each AEGT subsystem for > 15 continuous minutes." The requirement "with heaters operating" will be deleted.
There is no change to the frequency requirement, which remains "In accordance with the Surveillance Frequency Control Program."
2.2 TECHNICAL SPECIFICATIONS NO LONGER ALIGNED WITH LICENSE BASIS FENOC proposes to delete the following technical specifications because the FHB and FHBES are not credited in the current FHA analysis, and their APPLICABILITY statements, which read "During movement of recently irradiated fuel assemblies in the FHB," are not applicable. Where necessary, the word "Deleted" will be added to the TS.
- Delete TS 3.7.8, "Fuel Handling Building," in its entirety.
- Delete TS 3.7.9, "Fuel Handling Building Ventilation Exhaust System," in its entirety.
TS 3.7.7, "Fuel Pool Water Level," will be revised to add a parenthetical note (next page is 3.7-19) at the bottom of page 3.7-14. This change is necessary due to the deletion of TS pages associated with TS 3.7.8 and TS 3.7.9. This proposed change is a non-technical administrative change and further discussion in Section 3.0, TECHNICAL EVALUATIONS, is not required.
2.3 SECONDARY CONTAINMENT BYPASS LEAKAGE Revision to SR 3.6.1.3.9 FENOC proposes to revise the TS 3.6.1.3, "Primary Containment Isolation Valves (PCIVs)," SR 3.6.1.3.9, to align the secondary containment bypass leakage rate criterion to the license basis. With the revision, SR 3.6.1.3.9 will read "Verify the combined leakage rate for all secondary containment bypass leakage paths is < 0.1008 La when pressurized to > Pa." No other changes are proposed for this SR.
2.4 VENTILATION FILTER TESTING PROGRAM v Revision to TS 5.5.7. "Ventilation Filter Testing Program (VFTP)"
FENOC proposes to revise TS 5.5.7 as follows:
- All references to the "Fuel Handling Building" will be deleted. Testing of the FHB ventilation system in TS 5.5.7.a.b, 5.5.7.b.b, 5.5.7.c.b, 5.5.7.d.b, and 5.5.7.e.b will also be deleted. Additionally, TS 5.5.7.a.c will be renumbered to TS 5.5.7.a.b, and TS 5.5.7.d.c will be renumbered to TS 5.5.7.d.b.
- Charcoal adsorber testing requirements associated with the annulus exhaust gas treatment (AEGT) system will be deleted. Specifically, testing of the AEGT system charcoal adsorbers in TS 5.5.7.b.c and 5.5.7.c.c will be deleted.
Page 5 of 13
- Proposed revisions to TS 3.6.4.3, "Annulus Exhaust Gas Treatment (AEGT) System,"
and TS 3.7.3, "Control Room Emergency Recirculation (CRER) System," previously discussed the deletion of the requirement "with the heaters operating." TS 5.5.7.e for heater testing will be deleted in its entirety.
- For the CRER system, the license basis currently requires charcoal adsorbers during a design basis loss of coolant accident. With no operating heaters (that is, no humidity control), TS 5.5.7.c.a will list the required 95% RH test criterion for the charcoal adsorber sample. Additionally, the charcoal adsorber methyl iodine penetration testing criterion will be changed from 2.5% to 10%.
- For TS 5.5.7, references to Nuclear Regulatory Commission (NRC) Regulatory Guide (RG) 1.52, Revision 2, "Design, Testing, and Maintenance Criteria for Post-Accident Engineered-Safety-Feature Atmosphere Cleanup System Air Filtration and Absorption Units of Light-Water-Cooled Nuclear Power Plants," will be replaced with a reference to RG 1.52, Revision 4.
2.5 TECHNICAL SPECIFICATIONS TABLE OF CONTENTS Revision to TS Table of Contents FENOC proposes to revise the TS table of contents (TOC) as described below:
- The title of TS 3.3.6.1 will read "Primary Containment and Drywell Isolation Instrumentation." This TOC change, which adds the text "and Drywell" into the title, aligns the TOC with the title of TS 3.3.6.1 established by License Amendment No. 69, issued June 23, 1995 [Ref. 1].
- The title of TS 3.6.1.9 will read "Main Steam Shutoff Valves." This TOC change, which deletes the text "Isolation Valve (MSIV) Leakage Control System (LCS)" and replaces it with the text "Shutoff Valves," aligns the TOC with the title of TS 3.6.1.9 established by License Amendment No. 103, issued March 26, 1999 [Ref. 2].
- The title of TS 3.6.3.1, "Primary Containment Hydrogen Recombiners," will be removed in its entirety and replaced with "Deleted." This change aligns the TOC with License Amendment No. 135, issued on April 19, 2005 [Ref. 3].
- The title of TS 3.7.8, "Fuel Handling Building," will be removed in its entirety and replaced with "Deleted." This deletion is associated with a TS change proposed in this license amendment request.
- The title of TS 3.7.9, "Fuel Handling Building Ventilation Exhaust System," will be removed in its entirety and replaced with "Deleted." This deletion is associated with a TS change proposed in this license amendment request.
These proposed changes are considered non-technical administrative changes and further discussion in Section 3.0, TECHNICAL EVALUATIONS, is not required.
3.0 TECHNICAL EVALUATION
S 3.1 SYSTEM RUNTIME AND HEATER OPERATION Revised SR 3.6.4.3.1 and SR 3.7.3.1 Surveillance Requirements The revised SR 3.7.3.1 system runtime requirement of 15 continuous minutes, as proposed, will align with NUREG-1434, Revision 4, Volume 1, "Standard Technical Specifications - General Electric BWR/6 Plants." The revised runtime requirement also aligns with the NRC-approved Technical Specification Task Force (TSTF) Traveler 522,
Page 6 of 13 "Revise Ventilation System Surveillance Requirement to Operate for 10 Hours per Month,"
and RG 1.52, "Design, Inspection, and Testing Criteria for Air Filtration and Adsorption Units of Post-Accident Engineered-Safety-Feature Atmosphere Cleanup Systems in Light-Water-Cooled Nuclear Power Plants," Revision 4.
According to the updated safety analysis report (USAR), Section 6.5.1, the AEGT and CRER systems are engineered safety features (ESF) filter systems. Both systems have the same design bases and design functions, and charcoal adsorber plenum components.
Both systems include heaters currently used to maintain RH of the exhaust air at 70% or less. These system similarities support the following discussion regarding the proposed changes to SR 3.6.4.3.1 and their alignment to the changes proposed for SR 3.7.3.1.
The revised SR 3.6.4.3.1 system runtime requirement of 15 continuous minutes, as proposed, will align the AEGT system requirement to the CRER system runtime changes proposed for SR 3.7.3.1 (a similar ESF filter system, as described above).
NUREG-1434 and RG 1.52 provide the basis for changing the ventilation system runtime requirements from 10 continuous hours to 15 continuous minutes. From NUREG-1434, Volume 2, Bases for SR 3.7.3.1, "Systems without heaters need only be operated for > 15 minutes to demonstrate the function of the system." From RG 1.52, Section C.6.a, "Each ESF atmosphere cleanup train should be operated continuously for at least 15 minutes each month, with the heaters on (if so equipped), to justify the operability of the system and all its components."
Though currently equipped with heaters, FENOC will no longer require the AEGT and CRER systems to operate with their heaters. Revising SR 3.6.4.3.1 and SR 3.7.3.1 to remove the text "with the heaters operating," as proposed, is considered acceptable because FENOC is also revising the applicable charcoal adsorber testing requirements consistent with ventilation systems without heaters.
RG 1.52, Revision 4, Section C.4.i, states "systems without humidity control should perform laboratory testing of representative samples of activated carbon at a relative humidity of 95%." TSTF-522 states that "Plants which test ventilation system adsorption at a relative humidity of 95% do not require heaters for the ventilation system to perform its specified safety function" and "may eliminate the reference to heaters in the Surveillance Requirements and Bases." FENOC proposes to revise TS 5.5.7 to reflect changes in testing requirements for the AEGT and CRER systems consistent with TSTF-522 and RG 1.52, Revision 4.
3.2 TECHNICAL SPECIFICATIONS NO LONGER APPLICABLE TS 3.7.8 and TS 3.7.9 are only applicable during movement of recently irradiated fuel assemblies in the FHB. Deletion of these two technical specifications, TS 3.7.8 and TS 3.7.9, as proposed, is considered acceptable since their deletion will align the technical specifications with the license basis and the FHA analysis submitted to the NRC by FENOC on December 9, 2002 [Ref. 4]. In the submittal, FENOC identified use of an alternative source term radiological calculation to update the design basis for the FHA.
The submitted calculation took no credit for FHB integrity and no credit for the FHBES.
After its review, the NRC issued License Amendment No. 122 on March 4, 2003 [Ref. 5],
approving FENOC's requested license amendment.
Page 7 of 13 USAR Section 15.7.4, states "This accident [fuel handling accident outside containment] is not reanalyzed as part of the reload analysis as the fuel handling accident inside containment analysis is bounding." USAR Section 15.7.6 states, "Handling of 'recently irradiated fuel' is prohibited, because no dose calculations exist to address a fuel handling accident within the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after the core is subcritical." Additionally, the current configuration of the PNPP and the actions necessary to access and move irradiated fuel do not enable the movement of irradiated fuel that has been subcritical < 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> (that is, "recently irradiated fuel"). As such, a technical specification whose APPLICABILITY, CONDITION, or REQUIRED ACTION related to the allowed movement of "recently irradiated fuel" or irradiated fuel that has been subcritical < 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> should not apply, exist, or be performed.
The proposed deletion of TS 3.7.8 and TS 3.7.9 was reviewed against 10 CFR 50.36, "Technical specifications," and its criteria. Of the four criterion in 10 CFR 50.36, the following two criterion are cited in the Bases for TS 3.7.8 ancTTS 3.7.9.
Criterion 3. A structure, system, or component 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.
Criterion 4. A structure, system, or component which operating experience or probabilistic risk assessment has shown to be significant to public health and safety.
FENOC concludes that the proposed deletion of TS 3.7.8 and TS 3.7.9 is acceptable based on the following:
- The license basis prohibits the movement of irradiated fuel that has been subcritical < 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> (recently irradiated fuel).
- The current configuration of the PNPP and the actions necessary to access and move irradiated fuel do not enable the movement of irradiated fuel that has been subcritical < 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> (recently irradiated fuel).
- TS 3.7.8 and TS 3.7.9 are only applicable during the movement of recently irradiated fuel in the FHB, which is prohibited and not achievable at this time.
- The license basis does not credit the FHB or the FHBES in mitigating the consequences of a FHA in the FHB.
- The FHB and the FHBES no longer meet the 10 CFR 50.36 criteria for establishing a technical specification limiting condition for operation based on:
o The FHB and the FHBES are not relied upon to mitigate a FHA in the FHB.
o FENOC does not intend to revise existing accident analyses (FHA dose calculations) to re-credit the FHB or the FHBES during the movement of recently irradiated fuel.
- TS whose APPLICABILITY, CONDITION, or REQUIRED ACTION is only related to the movement of recently irradiated fuel should not apply, exist, or be performed.
The FHB will remain categorized as a safety-related, Seismic Category I structure and the FHBES will remain a safety-related, Seismic Category I system.
Page 8 of 13 3.3 SECONDARY CONTAINMENT BYPASS LEAKAGE Revised SR 3.6.1.3.9 The revised surveillance requirement, as proposed, is considered acceptable since it will align with the license basis, USAR Section 15.6.5.5.1.4, which states "The analysis conservatively assumes 10.08% [percent] of the primary containment leakage bypasses the secondary containment..," The license basis was updated as part of the alternative source term initiative submitted to the NRC by FENOC on December 6, 2013 [Ref. 6]. In the submittal, FENOC identified use of an alternative source term radiological calculation to revise the allowable secondary containment bypass leakage rate to 10.08%. After its review, the NRC issued License Amendment No. 166 on March 30, 2015 [Ref. 7],
approving FENOC's requested license amendment.
This SR revision does not require a change to existing testing methods and prescribed testing will continue to be performed in accordance with approved procedures, thus ensuring the secondary containment is capable of performing its design basis function.
3.4 VENTILATION FILTER TESTING PROGRAM Revised TS 5.5.7. "Ventilation Filter Testing Program (VFTPV The revised TS, as proposed, is considered acceptable since it will align with the license basis and the proposed TS changes discussed herein.
Revised TS 5.5.7.a.b, 5.5.7.b.b, 5.5.7.c.b, 5.5.7.d.b, and 5.5.7.e.b, which deletes all references to the "Fuel Handling Building," is considered acceptable since these changes will align with the current FHA analysis. The analysis took no credit for the FHB or the FHBES. Additionally, TS 3.7.9, "Fuel Handling Building Exhaust System," is proposed for deletion. With the system deleted from the technical specifications, there is no basis to provide testing criteria for the system in TS 5.5.7.
Revised TS 5.5.7.b.c and 5.5.7.c.c, which deletes charcoal adsorber testing requirements for the AEGT system, is considered acceptable since they will align with USAR Section 15.6.5.5.1. According to the license basis, none of the accident analyses credit iodine removal by charcoal adsorbers in the annulus exhaust gas treatment (AEGT) system. With no requirement to have charcoal adsorbers, there is no need to provide testing criteria for the charcoal adsorbers in TS 5.5.7.
Revised TS 5.5.7.e deletes heater testing in its entirety based on the following
- The previously discussed revisions to TS 3.6.4.3, "Annulus Exhaust Gas Treatment (AEGT) System," and TS 3.7.3, "Control Room Emergency Recirculation (CRER)
System," propose deleting the requirement "with the heaters operating." With no requirement to have the heaters operating, testing of the AEGT and CRER system heaters in TS 5.5.7.e.a and 5.5.7.e.c will be deleted.
- The previously discussed deletion of the FHBES TS removes the requirement to test the FHBES heaters in TS 5.5.7.e.b.
Revised TS 5.5.7.C, which changes the CRER system's charcoal adsorber testing criterion from 70% RH to 95% RH and the methyl iodine penetration criterion from 2.5% to 10%, is considered acceptable since they align with NUREG-1434 and the license basis as discussed below. ^
Page 9 of 13
- Deleting requirements for heaters is justified because the testing requirements of ASTM D3803-1989 for a system without heaters will be utilized. However, this results in a CRER system without humidity control and compliance with the current PNPP TS 5.5.7.C testing criterion of 70% RH may not be achievable at all times.
NUREG-1434, TS 5.5.8.C, specifically addresses RH criterion as follows:
ASTM D3803-1989 is a more stringent testing standard because it does not differentiate between used and new charcoal, it has a longer equilibrium period performed at a temperature of 30°C (86°F) and a relative humidity (RH) of 95% (or 70% RH with humidity control) and it has more stringent tolerances that improve repeatability of the test.
For the PNPP, ASTM D3803-1989 is already cited in TS 5.5.7. However, not having heaters results in a lack of humidity control. As such, the CRER charcoal adsorber testing criterion shall reflect the NUREG-1434, TS 5.5.8 testing criterion of 95% RH (with no humidity control).
- Changing the methyl iodine penetration criterion from 2.5% to 10% for the CRER system is consistent with USAR Section 15.6.5.5.1, which states "The LOCA analysis is based on... utilizing elemental and organic iodine removal efficiencies of 80 percent for the control room emergency recirculation system charcoal adsorbers." The LOCA analysis is the only accident analysis that credits the control room emergency recirculation system charcoal adsorbers. NUREG-1434, TS 5.5.8, provides the methodology for determining methyl iodine allowable penetration criterion as follows:
Allowable Penetration = [(100% - Methyl Iodine Efficiency for Charcoal Credited in Licensee's Accident Analysis) / Safety Factor]
When ASTM D3803-1989 is used with 30°C (86°F) and 95% RH (or 70% RH with humidity control) is used, the staff accepts a safety factor > 2 for systems with or without humidity control.
As stated, the license basis cites an 80 percent removal efficiency for the CRER system. Inserting the 80 percent value into the NUREG-1434 equation results in the following methyl iodine penetration criterion:
Allowable Penetration = [(100% - 80%) / 2] = 10 percent.
- Changing from RG 1.52, Revision 2, to RG 1.52, Revision 4, is considered acceptable based on the following:
o RG 1.52, Revision 4, is the latest edition of this document.
o Per RG 1.52, Revision 4, Section C.4.i, "...systems without humidity control
[without heaters] should perform laboratory testing of representative samples of activated carbon at a relative humidity of 95%." This supports the previously discussed revisions to delete the "with heater operating" requirement from TS 3.6.4.3, "Annulus Exhaust Gas Treatment (AEGT) System," and TS 3.7.3, "Control Room Emergency Recirculation (CRER) System."
o Per RG 1.52, Revision 4, Section C.6.a, "Each ESF atmosphere cleanup train should be operated continuously for at least 15 minutes each month, with heaters on (if so equipped), to justify the operability of the system and all of its components." This supports the previously discussed system runtime revisions in TS 3.6.4.3 and TS 3.7.3.
Page 10 of 13 o Per RG 1.52, Revision 4, Section C.7.b, "Sampling and analysis should be performed... at least once every 24 months." The 24-month testing frequency aligns with the current PNPP 24-month operating cycle.
o The NRC-approved Technical Specification Task Force (TSTF) Traveler 522, "Revise Ventilation System Surveillance Requirement to Operate for 10 Hours per Month," used the guidance in RG 1.52, Revision 3, in support of changing system runtime and heater operating requirements. RG 1.52, Revision 4, maintains the same system runtime and heater operating requirements.
4.0 REGULATORY EVALUATION
The proposed amendment to the Perry Nuclear Power Plant (PNPP) Technical Specifications (TS) would:
- Revise TS 3.7.3, "Control Room Emergency Recirculation (CRER) System," to change the runtime requirement from "10 continuous hours" to "15 continuous minutes," and to delete "with heaters operating" in Surveillance Requirement (SR) 3.7.3.1.
- Revise TS 3.6.4.3, "Annulus Exhaust Gas Treatment (AEGT) System," to change the runtime requirement from "10 continuous hours" to "15 continuous minutes," and to delete "with heaters operating" in SR 3.6.4.3.1 to align it with proposed changes to SR 3.7.3.1.
- Delete TS 3.7.8, "Fuel Handling Building," to align with the license basis.
- Delete TS 3.7.9, "Fuel Handling Building Ventilation Exhaust System," to align with the license basis.
- Revise TS 3.7.7, "Fuel Pool Water Level," to add a parenthetical note at the bottom of the page, which cites the next TS page number. This is necessary due to the deletion of TS pages associated with TS 3.7.8 and TS 3.7.9.
- Revise TS 3.6.1.3, "Primary Containment Isolation Valves," to increase the allowable secondary containment bypass leakage rate from 0.0504 La to 0.1008 La and align with the license basis.
- Revise TS 5.5.7, "Ventilation Filter Testing Program (VFTP)," to align with the license basis and other proposed changes to the TS.

contents with changes associated with previously issued license amendments.
4.1 Significant Hazards Consideration FirstEnergy Nuclear Operating Company (FENOC) has evaluated whether or not a significant hazards consideration is involved with the proposed amendment by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of amendment," as discussed below:
- 1. Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?
Response: No The proposed amendment involves incorporating technical specification changes that reflect previously approved license basis changes as part of the alternative source term (AST) initiative, aligns some TS sections with NUREG-1434, Revision 4, and deletes two
Page 11 of 13 TS sections. The proposed amendment does not affect any accident mitigating feature or increase the likelihood of malfunction for plant structures, systems and components.
Verification of operating the plant within prescribed limits will continue to be performed, as currently required by the applicable TS surveillance requirements. Compliance with and continued verification of the prescribed limits support the capability of the systems to perform their required design functions during all plant operating, accident, and station blackout conditions, consistent with the plant safety analyses.
The proposed amendment will not change any of the analyses associated with the PNPP Updated Safety Analysis Report Chapter 15 accidents because accident initiators and accident mitigation functions remain unchanged. The proposed amendment does not alter any assumptions previously made relative to evaluating the consequences of an accident.
Therefore, the proposed amendment 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 amendment does not involve physical alterations to the plant. No new or different type of equipment will be installed and there are no physical modifications required to existing installed equipment associated with the proposed changes. The proposed amendment does not create a credible failure mechanism, malfunction, or accident initiator not already considered in the design and licensing basis.
Therefore, the proposed amendment does not create the possibility of a new or different kind of accident from any accident previously evaluated.
- 3. Does the proposed amendment involve a significant reduction in a margin of safety?
Response: No.
Safety margins are applied to design and licensing basis functions and to the controlling values of parameters to account for various uncertainties and to avoid exceeding regulatory or licensing limits. The proposed amendment does not require a physical change to the plant, or affect design and licensing basis functions or controlling values of parameters for plant systems, structures, and components.
Therefore, the proposed amendment does not involve a significant reduction in a margin of safety.
Based on the responses to the three questions above, FENOC concludes that the proposed amendment does not involve a significant hazards consideration under the standards set forth in 10 CFR 50.92(c), and, accordingly, a finding of "no significant hazards consideration" is justified.
Page 12 of 13 4.2 Applicable Regulatory Requirements/Criteria The following regulatory requirements and criteria were reviewed during development of the proposed license amendment:
- NUREG-0800, "Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR Edition," Section 15.0.1, "Radiological Consequence Analyses Using Alternative Source Terms," Revision 0.
- RG 1.52, "Design, Inspection, and Testing Criteria for Air Filtration and Adsorption Units of Post-Accident Engineered-Safety-Feature Atmosphere Cleanup Systems in Light-Water-Cooled Nuclear Power Plants," Revision 4.
- 10 CFR 50.36, "Technical specifications."
FENOC has determined that the proposed amendment is consistent with the regulatory requirements and criteria described in the above cited documents. No new or revised radiological consequence analyses are necessary to support the changes proposed by this amendment. Radiological dose consequences resulting from a design basis accident are unchanged within the PNPP license basis. In accordance with technical specification requirements, the necessary quality of systems and components is maintained, facility operation will be within safety limits, and limiting conditions for operation will be met.
4.3 Conclusions 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 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.
5.0 ENVIRONMENTAL CONSIDERATION
A review has determined that the proposed amendment would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, or would change an inspection or surveillance requirement.
However, the proposed amendment does not involve (i) a significant hazards consideration, (ii) a significant change in the types or a significant increase in the amounts of any effluents that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed amendment.

The charcoal adsorbenAromovoo gaseous olomontal iodino and organic locnaes, andTfle final HEPA filter is provided to collect any carbon fines exhausted from the charcoal adsorber.
The AEGT System automatically starts and operates in response to actuation signals indicative of conditions or an accident that could require operation of the system. AEGT System flows are controlled by two motor operated control dampers installed in branch ducts. One duct exhausts air to the unit vent, (AEGT Subsystem A exhausts to the Unit 1 plant vent; AEGT Subsystem B exhausts to the Unit 2 plant vent), while the other recirculates air back to the annulus.
APPLICABLE The design basis for the AEGT System is to mitigate the SAFETY ANALYSES consequences of a loss of coolant accident. For all events analyzed, the AEGT System is shown to be automatically initiated to reduce, via filtration and adsorption, the radioactive material released to the environment.
The AEGT System satisfies Criterion 3 of the NRC Final Policy Statement on Technical Specification Improvements (58 FR 39132) in MODES 1. 2/ and 3. During MODES 4 and 5. there are no accident analyses that credit the AEGT System.
However, it was determined that Specifications should remain in place per Criterion 4 to address OPDRVs and fuel handling accidents.: Criterion 3 would apply if dose calculations are revised to credit the AEGT System during handling of recently irradiated fuel. i.e.. fuel that has occupied part of a critical reactor core within the previous 24 nours.
LCO Following a DBA. a minimum of one AEGT subsystem is required to maintain the secondary containment at a negative pressure with respect to the environment and to process gaseous releases. Meeting the LCO requirements for two independent operable subsystems ensures operation of at least one AEGT subsystem in the event of a single active failure.

OPDRVs assume that one or more fuel assemblies are loaded into the core. Therefore, if the fuel is fully off-loaded from the reactor vessel, the AEGT System is not required to be OPERABLE.
ACTIONS With one AEGT subsystem inoperable, the inoperable subsystem must be restored to OPERABLE status within 7 days. In this Condition, the remaining OPERABLE AEGT subsystem is adequate to perform the required radioactivity release control function. However, the overall system reliability is reduced because a single failure in the OPERABLE subsystem could result in the radioactivity release control function not being adequately performed. The 7 day Completion Time is based on consideration of such factors as the availabilit lability of the OPERABLE redundant AEGT subsystem and the low probability of a DBA occurring during this period.

The safety related function of the CRER System used to control radiation exposure consists of two independent and redundant high efficiency air filtration subsystems for treatment of recirculated air and a control room envelope (CRE) boundary that limits the inleakage of unfiltered air.
Each CRER subsystem consists of a demister. an oloctric
- heaterv a prefilter, a high efficiency particulate air (HEPA) filter, an activated charcoal adsorber section, a second HEPA filter, a fan. and the associated ductwork, dampers, and instrumentation. The demister is provided to remove entrainprl watt*r in tho a-ir i.*-si~ +u~ ~i~~4.~*- u^-i..

ut waiaf 4iia 1">i hmt/H-i of tho airctroam to looo t The prefilter removes large particulate matter, while the upstream HEPA filter is provided to remove fine particulate matter (which may be radioactive) and protect the charcoal from fouling. The charcoal adsorber removes gaseous elemental iodine and organic iodides, and the HEPA after filter is provided to collect any carbon fines exhausted from the charcoal adsorber. When emergency recirculation is activated, the supply fan in the associated control room HVAC subsystem also operates, and its normal flow rate is reduced to be compatible with the CRER fan discussed above (Ref. 2).
The CRE is the area within the confines of the CRE boundary that contains the spaces that control room occupants inhabit to control the unit during normal and accident conditions.
This area encompasses the control room, and may encompass other non-critical areas to which frequent personnel access or continuous occupancy is not necessary in the event of an accident. The CRE is protected for normal operation, natural events, and accident conditions. The CRE boundary is the combination of walls, floor, ceilings, ducting, doors, penetrations and equipment that physically form the CRE. The OPERABILITY of the CRE boundary must be maintained to ensure that the inleakage of unfiltered air into the CRE will not exceed the inleakage assumed in the licensing basis analysis of design basis accident (DBA) consequences to CRE occupants. The CRE and its boundary are defined in the Control Room Envelope Habitability Program.

NO CHANGES; PROVIDED CRER System FOR CONTEXT ONLY B 3 7 3 BASES BACKGROUND In addition to the safety related standby emergency (continued) filtration function, parts of the CRER System are operated to maintain the CRE environment during normal operation.
Upon receipt of the initiation signal(s) (indicative of conditions that could result in radiation exposure to CRE occupants), the CRER System automatically switches to the emergency recirculation mode of operation to minimize infiltration of contaminated air into the CRE. A system of dampers isolates the CRE. and CRE air flow is recirculated and processed through either or both of the two filter subsystems.
The CRER System is designed to maintain a habitable environment in the CRE for a 30 day continuous occupancy after a DBA. without exceeding 5 rem total effective dose equivalent (TEDE). CRER System operation in maintaining the CRE habitability is discussed in the USAR. Sections 6.5.1 and 6.4 (Refs. 1 and 2. respectively).

PERRY - UNIT 1 B 3.7-10a Revision No. 7
NO CHANGES; PROVIDED CRER System FOR CONTEXT ONLY B 3.7.3 BASES (continued)
APPLICABLE The ability of the CRER System to maintain the SAFETY ANALYSES habitability of the CRE is an explicit assumption for the safety analyses presented in the USAR. Chapters 6 and 15 (Refs. 3 and 4. respectively). The emergency recirculation mode of the CRER System is assumed to operate following a DBA. The radiological doses to CRE occupants as a result of the various DBAs are summarized in Reference 4. No single active or passive failure will cause the loss of ability to recirculate air in the CRE.
The CRER can provide protection from smoke and hazardous chemicals to CRE occupants. However, an evaluation of chemical hazards from onsite. offsite. and transportation sources has determined that the probability of a hazardous chemical spill resulting in unacceptable exposures is less than NRC licensing basis criteria. As a result, the plant licensing basis does not postulate hazardous chemical release events (Refs. 2 and 5). Therefore, no quantitative limits on inleakage of hazardous chemicals into the CRE have been established. A smoke assessment consistent with the guidance in Regulatory Guide 1.196 (Ref. 7) and NEI 99-03 Rev. 0 (Ref. 10) determined that reactor control capability can be maintained from either the Control Room or the remote shutdown controls during a smoke event (Ref. 6). Therefore, no quantitative limits on inleakage of smoke into the CRE have been established. Because inleakage limits for hazardous chemicals and smoke are not necessary to protect CRE occupants, the limit established for radiological events is the limiting value for CRE inleakage.
The CRER System satisfies Criterion *3 of the NRC Final Policy Statement on Technical Specification Improvements (58 FR 39132) in MODES 1. 2. or 3. During MODES 4 and 5. there are no accident analyses that credit the CRER System.
However, it was determined that Specifications should remain in place per Criterion 4 to address OPDRVs and fuel handling accidents. Criterion 3 would apply if dose calculations are revised tp credit the CRER System during handling of recently irradiated fuel. i.e.. fuel that has occupied part of a critical reactor core within the previous 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

- c. Hootorv demTster, ductwork, valves, and dampers are OPERABLE, and air circulation can be maintained.
In order for the CRER subsystems to be considered OPERABLE, the CRE boundary must be maintained such that the CRE occupant dose from a large radioactive release does not exceed the calculated dose in the licensing basis consequence analyses for DBAs, and that CRE occupants are protected from hazardous chemicals and smoke.
The LCO is modified by a Note allowing the CRE boundary to be opened intermittently under administrative controls.
This Note only applies to openings in the CRE boundary that can be rapidly restored to the design condition, such as doors, hatches, floor plugs, and access panels. For such openings (other than doors), these controls should be proceduralized and consist of stationing a dedicated individual at the opening who is in continuous communication with the operators in the CRE. This individual will have a method to rapidly close the opening and to restore the CRE boundary to a condition equivalent to the design condition when a need for CRE isolation is indicated. For entry and exit through doors, the administrative control of the opening is performed by the person(s) entering or exiting the area.
APPLICABILITY In MODES 1, 2. and 3. the CRER System must be OPERABLE to ensure that the CRE will remain nabitable during and following a DBA, since the DBA could lead to a fission product release.

NO CHANGES; PROVIDED CRER System FOR CONTEXT ONLY B 3.7.3 BASES APPLICABILITY In MODES 4 and 5, the probability and consequences of a DBA (continued) are reduced due to the pressure and temperature limitations in these MODES. Therefore, maintaining the CRER System OPERABLE is not required in MODE 4 or 5. except for the following situations under which significant radioactive releases can be postulated:
- a. During movement of recently irradiated fuel assemblies in the primary containment or fuel handling building; and
- b. During operations with a potential for draining the reactor vessel (OPDRVs).
Due to radioactive decay, handling of fuel only requires OPERABILITY of the Control Room Emergency Recirculation System when the fuel being handled is recently irradiated, i.e.. fuel that has occupied part of a critical reactor core within the previous 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

OPDRVs assume that one or more fuel assemblies are loaded into the core. Therefore, if the fuel is fully off-loaded from the reactor vessel, the CRER System is not required to be OPERABLE.
ACTIONS , AJL With one CRER subsystem inoperable for reasons other than an inoperable CRE boundary, the inoperable CRER subsystem must be restored to OPERABLE status within 7 days. With the unit in this condition, the remaining OPERABLE CRER subsystem is adequate to perform the CRE occupant protection function.
However, the overall reliability is reduced because a failure in the OPERABLE CRER subsystem could result in loss of CRER System function. The 7 day Completion Time is based on the low probability of a DBA occurring during this time period, and that the remaining CRER subsystem can provide the required capabilities.

If the unfiltered inleakage of potentially contaminated air past the CRE boundary and into the CRE can result in CRE occupant radiological dose greater than the calculated dose of the licensing basis analyses of DBA consequences (allowed to be up to 5 Rem TEDE). or inadequate protection of CRE occupants from hazardous chemicals or smoke, the CRE boundary is inoperable. As discussed in the Applicable Safety Analyses section, the current PNPP licensing basis identifies that CRE inleakage limits for hazardous chemicals and smoke are not necessary to protect CRE occupants:
therefore the limit established for radiological events is the limiting value for determining entry into Condition B for an inoperable CRE boundary. Actions must be taken to restore an OPERABLE CRE boundary within 90 days.
During the period that the CRE boundary is considered inoperable, action must be initiated to implement mitigating actions to lessen the effect on CRE occupants from the potential hazards of a radiological or cnemical event or a challenge from smoke. Actions must be taken within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to verify that in the event of a DBA, the mitigating actions will ensure that CRE occupant radiological exposures will not exceed the calculated dose of the licensing basis analyses of DBA consequences, and that CRE occupants are protected from hazardous chemicals and smoke. These mitigating actions (i.e., actions that are taken to offset the consequences of the Operable CRE boundary) should be preplanned for implementation upon entry into the condition, regardless of whether entry is intentional or unintentional.
These mitigating actions are outlined in the PNPP Control Room Envelope Habitability Program.
The 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> Completion Time is reasonable based on the low probability of a DBA occurring during this time period, and the use of mitigating actions. The 90 day Completion Time is reasonable based on the determination that the mitigating actions will ensure protection of CRE occupants within analyzed limits while limiting the probability that CRE occupants will have to implement protective measures that may adversely affect their ability to control the reactor and maintain it in a safe shutdown condition in the event of a DBA. In addition, the 90 day Completion Time is a reasonable time to diagnose, plan and possibly repair, and test most problems with the CRE boundary.

The Required Actions of Condition D are modified by a Note indicating that LCO 3.0.3 does not apply. If moving recently irradiated fuel assemblies while in MODE 1. 2 or 3. the fuel movement is independent of reactor operations. Therefore, inability to suspend movement of recently irradiated fuel assemblies is not sufficient reason to require a reactor shutdown. During movement of recently irradiated fuel assemblies in the primary containment or fuel handling building, or during OPDRVs, if the inoperable CRER subsystem cannot be restored to OPERABLE status within the required Completion Time of Condition A, the OPERABLE CRER subsystem may be placed in the emergency recirculation mode. This action ensures that the remaining subsystem is OPERABLE, that no failures that would prevent automatic actuation will occur, and that any active failure will be readily detected.
An alternative to Required Action D.I is to immediately suspend activities that present a potential for releasing significant amounts of radioactivity that might require isolation of the CRE. This places the unit in a condition that minimizes the accident risk.
If applicable, movement of recently irradiated fuel assemblies in the primary containment and fuel handling building must be suspended immediately. Suspension of these activities shall not preclude completion of movement of a component to a safe position. Also, if applicable, actions must be initiated immediately to suspend OPDRVs to minimize the probability of a vessel draindown and subsequent potential for fission product release.

Regardless of the plant operating MODE, anytime recently irradiated fuel is being handled in the FHB there is the potential for significant radioactive releases due to a FHA. and the FHB is required to mitigate the consequences.
