The Safe Shutdown path (1 OR 2) least impacted by the fire in each area was identified AN..._D protected.

It is assumed that only one path is available for shutdown for the purpose of engineering analysis.

This does NOT prevent operator use of systems outside of the protected path, IF they continue to function as required.

For fire areas where protection of one path cannot be achieved, such as the Main Control Room, Cable Spreading Room, AND Computer Room, Remote Shutdown Systems (Path 3) were identified AND protected from the fire area.* Where circuit failures to protected path components can be compensated for by a manual operator action, those actions are contained in this procedure.

  • The components that are protected WITHIN each Safe Shutdown Path, as determined below, are given in Attachment 3 (Path 1), Attachment 4 (Path 2), AN Attachment 5 (Path 3 OR Remote Shutdown).

These component lists are to be considered the minimum equipment that will survive in a given fire area. Other equipment, although NO_._I specifically protected OR analyzed, may survive the fire. Circuit faults to unanalyzed equipment have NOT been evaluated.

The Safe Shutdown Path (1 OR 2) least impacted by the fire in each area was identified AND analyzed.

It is assumed that only one path is available for shutdown for the purpose of engineering analysis.

This does NOT prevent Operator use of systems outside of the analyzed path IFE they continue to function as required.

For fire areas where protection of one path CANNOT be achieved, such as the Main Control Room, Cable Spreading Room AND Computer Room, Remote Shutdown Systems (Path 3) were identified AND~. analyzed.* Where circuit failures to analyzed path components can be compensated for by a manual operator action, those actions are contained in this procedure.

  • The components that are analyzed WITHIN each Safe Shutdown Path, as determined below, are given in Attachment 4 (Path 1), Attachment 5 (Path 2) AND Attachment 6 (Path 3 -Remote Shutdown).

These component lists are to be considered the minimum equipment that will survive in a given fire area. Other equipment, may survive the fire. Circuit faults to unanalyzed equipment have NOT been evaluated.

The temperature of the water injected into the RPV is 1 00 0 F.6. Plant-specific data required to calculate the Minimum Steam Cooling RPV Water Level is as follows: a. Minimum active fuel length fraction which must be covered to maintain peak clad temperature below 1 500 0 F with injection.

b. Active fuel length c. Water level at the bottom of the active fuel E. Minimum Zero-Injection RPV Water Level (LT 31) (LCT 31)1. The Minimum Zero-Injection RPV Water Level is defined to be the lowest RPV water level at which the covered portion of the Reactor core will generate sufficient steam to preclude any clad temperature in the uncovered portion of the core form exceeding 1 800 0 F. This Water Level is utilized to preclude significant fuel damage and hydrogen generation for as long as possible.2. This is the level at which Steam Cooling Without injection is used in the EOPs.A cold shutdown rod configuration must exist to use this core cooling method.3.

210 V25 Page 1 of 6 RCS Operational LEAKAGE B 3.4.4 B 3.4 REACTOR COOLANT SYSTEM (RCS)B 3.4.4 RCS Operational LEAKAGE BASES BACKGROUND The RCS includes systems and components that contain or transport the coolant to or from the reactor core. The pressure containing components of the RCS and the portions of connecting systems out to and including the isolation valves define the reactor coolant pressure boundary (RCPB). The joints of the RCPB components are welded or bolted.During plant life, the joint and valve interfaces can produce varying amounts of reactor coolant LEAKAGE, through either normal operational wear or mechanical deterioration.

Limits on RCS operational LEAKAGE are required to ensure appropriate action is taken before the integrity of the RCPB is impaired.

This LCO specifies the types and limits of LEAKAGE. This protects the RCS pressure boundary described in 10 CFR 50.2, 10 CFR 50.55a(c), and GDC 55 of 10 CFR 50, Appendix A (Refs. 1, 2, and 3).The safety significance of RCS LEAKAGE from the RCPB varies widely depending on the source, rate, and duration.

Therefore, detection of LEAKAGE in the primary containment is necessary.

Methods for quickly separating the identified LEAKAGE from the unidentified LEAKAGE are necessary to provide the operators quantitative information to permit them to take corrective action should a leak occur that is detrimental to the safety of the facility or the public.A limited amount of leakage inside primary containment is expected from auxiliary systems that cannot be made 100% leaktight.

Leakage from these systems should be detected and isolated from the primary containment atmosphere, if possible, so as not to mask RCS operational LEAKAGE detection.

This LCO deals with protection of the RCPB from degradation and the core from inadequate cooling, in addition to preventing the accident analyses radiation release assumptions from being exceeded.

The consequences of violating this LCO include the possibility of a loss of coolant accident.APPLICABLE The allowable RCS operational LEAKAGE limits are based on the SAFETY ANALYSES predicted and experimentally observed behavior of pipe cracks. The normally expected background LEAKAGE due to equipment design (continued)

HATCH UNIT 1 .-3RVSO B 3.4-13 REVISION 0 V25 Page 2 of 6 RCS Operational LEAKAGE B 3.4.4 BASES APPLICABLE and the detection capability of the instrumentation for determining SAFETY ANALYSES system LEAKAGE were also considered.

The evidence from (continued) experiments suggests that, for LEAKAGE even greater than the specified unidentified LEAKAGE limits, the probability is small that the imperfection or crack associated with such LEAKAGE would grow rapidly.The unidentified LEAKAGE flow limit allows time for corrective action before the RCPB could be significantly compromised.

The 5 gpm limit is a small fraction of the calculated flow from a critical crack in the primary system piping. Crack behavior from experimental programs (Refs. 4 and 5) shows that leakage rates of hundreds of gallons per minute will precede crack instability (Ref. 6).The low limit on increase in unidentified LEAKAGE assumes a failure mechanism of intergranular stress corrosion cracking (IGSCC) that produces tight cracks. This flow increase limit is capable of providing an early warning of such deterioration.

No applicable safety analysis assumes the total LEAKAGE limit. The total LEAKAGE limit considers RCS inventory makeup capability and drywell floor sump capacity.RCS operational LEAKAGE satisfies Criterion 2 of the NRC Policy Statement (Ref. 9).LCO RCS operational LEAKAGE shall be limited to: a. Pressure Boundary LEAKAGE No pressure boundary LEAKAGE is allowed, being indicative of material degradation.

LEAKAGE of this type is unacceptable as the leak itself could cause further deterioration, resulting in higher LEAKAGE. Violation of this LCO could result in continued degradation of the RCPB.LEAKAGE past seals and gaskets is not pressure boundary LEAKAGE.b.

Violation of this LCO could result in continued degradation of the RCPB.c. Total LEAKAGE The total LEAKAGE limit is based on a reasonable minimum detectable amount. The limit also accounts for LEAKAGE from known sources (identified LEAKAGE).

Violation of this LCO indicates an unexpected amount of LEAKAGE and, therefore, could indicate new or additional degradation in an RCPB component or system.d. Unidentified LEAKAGE Increase An unidentified LEAKAGE increase of > 2 gpm within the previous 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period indicates a potential flaw in the RCPB and must be quickly evaluated to determine the source and extent of the LEAKAGE. The increase is measured relative to the steady state value; temporary changes in LEAKAGE rate as a result of transient conditions (e.g., startup) are not considered.

As such, the 2 gpm increase limit is only applicable in MODE 1 when operating pressures and temperatures are established.

Violation of this LCO could result in continued degradation of the RCPB.APPLICABILITY In MODES 1, 2, and 3, the RCS operational LEAKAGE LCO applies, because the potential for RCPB LEAKAGE is greatest when the reactor is pressurized.

In MODES 4 and 5, RCS operational LEAKAGE limits are not required since the reactor is not pressurized and stresses in the RCPB materials and potential for LEAKAGE are reduced.ACTIONS A._I With RCS unidentified or total LEAKAGE greater than the limits, actions must be taken to reduce the leak.

The Safe Shutdown path (1 OR 2) least impacted by the fire in each area was identified AN..._D protected.

It is assumed that only one path is available for shutdown for the purpose of engineering analysis.

This does NOT prevent operator use of systems outside of the protected path, IF they continue to function as required.

For fire areas where protection of one path cannot be achieved, such as the Main Control Room, Cable Spreading Room, AND Computer Room, Remote Shutdown Systems (Path 3) were identified AND protected from the fire area.* Where circuit failures to protected path components can be compensated for by a manual operator action, those actions are contained in this procedure.

  • The components that are protected WITHIN each Safe Shutdown Path, as determined below, are given in Attachment 3 (Path 1), Attachment 4 (Path 2), AN Attachment 5 (Path 3 OR Remote Shutdown).

These component lists are to be considered the minimum equipment that will survive in a given fire area. Other equipment, although NO_._I specifically protected OR analyzed, may survive the fire. Circuit faults to unanalyzed equipment have NOT been evaluated.

210 V25 Page 1 of 6 RCS Operational LEAKAGE B 3.4.4 B 3.4 REACTOR COOLANT SYSTEM (RCS)B 3.4.4 RCS Operational LEAKAGE BASES BACKGROUND The RCS includes systems and components that contain or transport the coolant to or from the reactor core. The pressure containing components of the RCS and the portions of connecting systems out to and including the isolation valves define the reactor coolant pressure boundary (RCPB). The joints of the RCPB components are welded or bolted.During plant life, the joint and valve interfaces can produce varying amounts of reactor coolant LEAKAGE, through either normal operational wear or mechanical deterioration.

Limits on RCS operational LEAKAGE are required to ensure appropriate action is taken before the integrity of the RCPB is impaired.

This LCO specifies the types and limits of LEAKAGE. This protects the RCS pressure boundary described in 10 CFR 50.2, 10 CFR 50.55a(c), and GDC 55 of 10 CFR 50, Appendix A (Refs. 1, 2, and 3).The safety significance of RCS LEAKAGE from the RCPB varies widely depending on the source, rate, and duration.

Therefore, detection of LEAKAGE in the primary containment is necessary.

Methods for quickly separating the identified LEAKAGE from the unidentified LEAKAGE are necessary to provide the operators quantitative information to permit them to take corrective action should a leak occur that is detrimental to the safety of the facility or the public.A limited amount of leakage inside primary containment is expected from auxiliary systems that cannot be made 100% leaktight.

Leakage from these systems should be detected and isolated from the primary containment atmosphere, if possible, so as not to mask RCS operational LEAKAGE detection.

This LCO deals with protection of the RCPB from degradation and the core from inadequate cooling, in addition to preventing the accident analyses radiation release assumptions from being exceeded.

The consequences of violating this LCO include the possibility of a loss of coolant accident.APPLICABLE The allowable RCS operational LEAKAGE limits are based on the SAFETY ANALYSES predicted and experimentally observed behavior of pipe cracks. The normally expected background LEAKAGE due to equipment design (continued)

HATCH UNIT 1 .-3RVSO B 3.4-13 REVISION 0 V25 Page 2 of 6 RCS Operational LEAKAGE B 3.4.4 BASES APPLICABLE and the detection capability of the instrumentation for determining SAFETY ANALYSES system LEAKAGE were also considered.

The evidence from (continued) experiments suggests that, for LEAKAGE even greater than the specified unidentified LEAKAGE limits, the probability is small that the imperfection or crack associated with such LEAKAGE would grow rapidly.The unidentified LEAKAGE flow limit allows time for corrective action before the RCPB could be significantly compromised.

The 5 gpm limit is a small fraction of the calculated flow from a critical crack in the primary system piping. Crack behavior from experimental programs (Refs. 4 and 5) shows that leakage rates of hundreds of gallons per minute will precede crack instability (Ref. 6).The low limit on increase in unidentified LEAKAGE assumes a failure mechanism of intergranular stress corrosion cracking (IGSCC) that produces tight cracks. This flow increase limit is capable of providing an early warning of such deterioration.

No applicable safety analysis assumes the total LEAKAGE limit. The total LEAKAGE limit considers RCS inventory makeup capability and drywell floor sump capacity.RCS operational LEAKAGE satisfies Criterion 2 of the NRC Policy Statement (Ref. 9).LCO RCS operational LEAKAGE shall be limited to: a. Pressure Boundary LEAKAGE No pressure boundary LEAKAGE is allowed, being indicative of material degradation.

LEAKAGE of this type is unacceptable as the leak itself could cause further deterioration, resulting in higher LEAKAGE. Violation of this LCO could result in continued degradation of the RCPB.LEAKAGE past seals and gaskets is not pressure boundary LEAKAGE.b.

Violation of this LCO could result in continued degradation of the RCPB.c. Total LEAKAGE The total LEAKAGE limit is based on a reasonable minimum detectable amount. The limit also accounts for LEAKAGE from known sources (identified LEAKAGE).

Violation of this LCO indicates an unexpected amount of LEAKAGE and, therefore, could indicate new or additional degradation in an RCPB component or system.d. Unidentified LEAKAGE Increase An unidentified LEAKAGE increase of > 2 gpm within the previous 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period indicates a potential flaw in the RCPB and must be quickly evaluated to determine the source and extent of the LEAKAGE. The increase is measured relative to the steady state value; temporary changes in LEAKAGE rate as a result of transient conditions (e.g., startup) are not considered.

As such, the 2 gpm increase limit is only applicable in MODE 1 when operating pressures and temperatures are established.

Violation of this LCO could result in continued degradation of the RCPB.APPLICABILITY In MODES 1, 2, and 3, the RCS operational LEAKAGE LCO applies, because the potential for RCPB LEAKAGE is greatest when the reactor is pressurized.

In MODES 4 and 5, RCS operational LEAKAGE limits are not required since the reactor is not pressurized and stresses in the RCPB materials and potential for LEAKAGE are reduced.ACTIONS A._I With RCS unidentified or total LEAKAGE greater than the limits, actions must be taken to reduce the leak.
