| The LPCI is one of the systems that comprise the Emergency Core Cooling System (ECCS). Itis provided to automatically reflood the reactor core in time to limit cladding temperatures after a nuclear system loss-of-coolant accident (LOCA) when the reactor vessel pressure is below the shutoff head of the pumps. The LPCI system provides cooling by flooding, which differs from the Core Spray System that provides cooling by spraying. When the nuclear system pressure decreases to the pumping head of LPCI system, the check valve in the injection line opens and LPCI water is pumped into the reactor vessel to reflood the core. As stated in Title 10 of the Code of Federal Regulations (10 CFR), Section 50.46, the purposeof the ECCSs is to remove the residual and decay heat from the reactor core so that fuel clad melting is prevented and fuel clad damage is acceptably minimized. The criterion against which the ECCS System performance is measured is that ECCS systems shall limit cladding peak temperature to 2200 °F.

| Description of ChangeThe change removes an SR that verifies that the LPCI loop discharge crosstie valve is in theclosed position with its motive power removed. The LPCI loop discharge crosstie valve has been physically removed and the associated piping has been capped or closed with a blind flange. The LPCI loop crosstie valve was physically removed and the associated piping capped orclosed with a blind flange as part of the Unit 1 restart effort. The removal of the crosstie valve also reduces the maintenance in a high-radiation area and, in turn, reduces ALARA (as low as reasonably achievable) concerns. Crosstie capability is not required for the mitigation of design basis events. EvaluationThe LPCI system previously had the ability to crosstie the redundant loops. This configurationprovided the LPCI system the flexibility to provide make-up flow into either of the loops. During normal operation the loops were isolated from one another through the use of a normally closed LPCI loop crosstie valve with the motive power removed.The purpose for the LPCI loop crosstie was for both LPCI loops to be able to provide reactormake-up flow into either of the two reactor recirculation loops under various LOCA pipe break scenarios. Subsequent to plant construction and licensing, analyses determined that the crosstie capability, under certain accident and single-failure scenarios, could result in the loss of injection from both LPCI loops. Additionally, analyses determined that the crosstie capability was not required for the mitigation of any design-basis events.The existence of the LPCI loop crosstie line was determined to be a liability in plant design andan SR was placed in TS Section 3.5.1, ECCS (Emergency Core Cooling System) - Operating.
| |
| SR 3.5.1.4 states, "Verify the LPCI cross tie valve is closed and power is removed from the valve operator." The frequency of this requirement is once every 31 days. This SR was intended to ensure the plant was in an analyzed condition.The LPCI system design has been changed to eliminate the crosstie ability. In this change, theLPCI loop crosstie valve has been physically removed and the associated piping has been capped or closed with a blind flange. This change was made as part of the Unit 1 restart effort.
| |
| The crosstie valve was not required for mitigation of design basis accidents. This design change makes it physically impossible for flow to occur between the two LPCI loops. The proposed change eliminates SR 3.5.1.4. With the removal of the LPCI loop crosstie valve,SR 3.5.1.4 is no longer necessary. The NRC staff reviewed the information supplied by the applicant and the Updated Final SafetyAnalysis Report, and concludes that the change in the mechanical separation inline from an isolation valve to a capped pipe does not affect adversely any safety function of the LPCI system. Therefore, the proposed TS change associated with this modification is acceptable.The licensee also provided its marked up changes to the affected TS Bases. The NRC staffhas no objection to the proposed TS Bases changes.

SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 268 TO RENEWED FACILITY OPERATING LICENSE NO. DPR-33 TENNESSEE VALLEY AUTHORITY BROWNS FERRY NUCLEAR PLANT, UNIT 1 DOCKET NO. 50-259
1.0 INTRODUCTION
By letter to the U.S. Nuclear Regulatory Commission (NRC), dated November 6, 2006, the Tennessee Valley Authority (the licensee) submitted a request for changes to the Browns Ferry Nuclear Plant, Unit 1, Technical Specifications (TS). The requested change would delete TS Surveillance Requirement (SR) 3.5.1.4, which requires monthly verification that the Low Pressure Coolant Injection (LPCI) Crosstie valve is in the closed position with its motive power removed.
2.0 REGULATORY EVALUATION
The LPCI is one of the systems that comprise the Emergency Core Cooling System (ECCS). It is provided to automatically reflood the reactor core in time to limit cladding temperatures after a nuclear system loss-of-coolant accident (LOCA) when the reactor vessel pressure is below the shutoff head of the pumps. The LPCI system provides cooling by flooding, which differs from the Core Spray System that provides cooling by spraying. When the nuclear system pressure decreases to the pumping head of LPCI system, the check valve in the injection line opens and LPCI water is pumped into the reactor vessel to reflood the core.
As stated in Title 10 of the Code of Federal Regulations (10 CFR), Section 50.46, the purpose of the ECCSs is to remove the residual and decay heat from the reactor core so that fuel clad melting is prevented and fuel clad damage is acceptably minimized. The criterion against which the ECCS System performance is measured is that ECCS systems shall limit cladding peak temperature to 2200 °F.
3.0 TECHNICAL EVALUATION
Description of Change The change removes an SR that verifies that the LPCI loop discharge crosstie valve is in the closed position with its motive power removed. The LPCI loop discharge crosstie valve has been physically removed and the associated piping has been capped or closed with a blind flange.
The LPCI loop crosstie valve was physically removed and the associated piping capped or closed with a blind flange as part of the Unit 1 restart effort. The removal of the crosstie valve also reduces the maintenance in a high-radiation area and, in turn, reduces ALARA (as low as reasonably achievable) concerns. Crosstie capability is not required for the mitigation of design basis events.
Evaluation The LPCI system previously had the ability to crosstie the redundant loops. This configuration provided the LPCI system the flexibility to provide make-up flow into either of the loops. During normal operation the loops were isolated from one another through the use of a normally closed LPCI loop crosstie valve with the motive power removed.
The purpose for the LPCI loop crosstie was for both LPCI loops to be able to provide reactor make-up flow into either of the two reactor recirculation loops under various LOCA pipe break scenarios. Subsequent to plant construction and licensing, analyses determined that the crosstie capability, under certain accident and single-failure scenarios, could result in the loss of injection from both LPCI loops. Additionally, analyses determined that the crosstie capability was not required for the mitigation of any design-basis events.
The existence of the LPCI loop crosstie line was determined to be a liability in plant design and an SR was placed in TS Section 3.5.1, ECCS (Emergency Core Cooling System) - Operating.
SR 3.5.1.4 states, Verify the LPCI cross tie valve is closed and power is removed from the valve operator. The frequency of this requirement is once every 31 days. This SR was intended to ensure the plant was in an analyzed condition.
The LPCI system design has been changed to eliminate the crosstie ability. In this change, the LPCI loop crosstie valve has been physically removed and the associated piping has been capped or closed with a blind flange. This change was made as part of the Unit 1 restart effort.
The crosstie valve was not required for mitigation of design basis accidents. This design change makes it physically impossible for flow to occur between the two LPCI loops.
The proposed change eliminates SR 3.5.1.4. With the removal of the LPCI loop crosstie valve, SR 3.5.1.4 is no longer necessary.
The NRC staff reviewed the information supplied by the applicant and the Updated Final Safety Analysis Report, and concludes that the change in the mechanical separation inline from an isolation valve to a capped pipe does not affect adversely any safety function of the LPCI system. Therefore, the proposed TS change associated with this modification is acceptable.
The licensee also provided its marked up changes to the affected TS Bases. The NRC staff has no objection to the proposed TS Bases changes.
4.0 STATE CONSULTATION
In accordance with the Commission's regulations, the Alabama State official was notified of the proposed issuance of the amendment. The State official had no comments.
5.0 ENVIRONMENTAL CONSIDERATION
The amendment changes a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 and changes SRs.
The NRC staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration, and there has been no public comment on such finding (71 FR 67166). Accordingly, the amendment meets the eligibility criteria for categorical exclusion 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 the amendment.
6.0 CONCLUSION
The Commission has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) 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.
