SUMMARY

DESCRIPTION The proposed amendment will adopt TSTF-471-A, Revision 1, Eliminate Use of the Term CORE ALTERATIONS in ACTIONS and Notes, with site-specific variations. This proposed change eliminates the defined term CORE ALTERATIONS and all uses of the term from the TS and Bases. The proposed amendment also adopts TSTF-571-T, Revision 0, Revise Actions for Inoperable Source Range Neutron Flux Monitor, which changes TS 3.9.3, Nuclear Instrumentation, to ensure that no actions are taken that could alter the core reactivity when a required core subcritical neutron flux monitor is inoperable. The proposed amendment also makes an administrative change to reformat the page numbering of TS Section 5.0 and remove unused pages for ease of future changes.

2.0 DETAILED DESCRIPTION 2.1 System Design and Operation The OPERABILITY of the minimum AC sources, DC sources, inverters, and distribution subsystems during MODES 5 and 6 and during movement of irradiated fuel assemblies ensures that:

a. The unit can be maintained in the shutdown or refueling condition for extended periods;
b. Sufficient instrumentation and control capability is available for monitoring and maintaining the unit status; and
c. Adequate power is provided to mitigate events postulated during shutdown, such as a fuel handling accident.

The limit on the boron concentrations of the Reactor Coolant System (RCS) and the refueling cavity during refueling ensures that the reactor remains subcritical during MODE 6.

Core subcritical neutron flux monitors are used during refueling operations to monitor the core reactivity condition. The installed core subcritical neutron flux monitors are part of the Nuclear Instrumentation System (NIS). These detectors (N-31, N-32, N-51, and N-52) are located external to the reactor vessel and detect neutrons leaking from the core. The detectors provide continuous visual indication in the control room. The installed BF3 neutron flux monitors provide an audible indication to alert operators in containment to a possible dilution accident.

2.2 Current Technical Specifications Requirements The following PINGP Units 1 and 2 TS include discussion of CORE ALTERATIONS:

1.1 Definitions includes a definition of CORE ALTERATIONS.

Page 2 of 14

L-PI-21-007 NSPM Enclosure TS 3.8.2, AC Sources - Shutdown, Required Actions A.1 and B.1 require suspension of CORE ALTERATIONS if a required path or a required diesel generator, respectively, is inoperable while in MODES 5 or 6 or during movement of irradiated fuel assemblies.

TS 3.8.5, DC Sources - Shutdown, Required Action B.1 requires suspension of CORE ALTERATIONS if one required DC electrical power subsystem inoperable for reasons other than an inoperable battery charger while in MODES 5 or 6 or during movement of irradiated fuel assemblies.

TS 3.8.8, Inverters - Shutdown, Required Action A.1 requires suspension of CORE ALTERATIONS if one required inverter is inoperable while in MODES 5 or 6 or during movement of irradiated fuel assemblies.

TS 3.8.10, Distribution Systems - Shutdown, Required Action A.2.1 requires suspension of CORE ALTERATIONS if one or more required safeguards AC, DC, or Reactor Protection Instrument AC electrical power distribution subsystem is inoperable while in MODES 5 or 6 or during movement of irradiated fuel assemblies.

TS 3.9.1, Boron Concentration, Required Action A.1 requires suspension of CORE ALTERATIONS if Reactor Coolant System (RCS) boron concentration is not within limits specified in the Core Operating Limits Report (COLR) while in MODE 6.

TS 3.9.3, Nuclear Instrumentation, Required Actions A.1 and C.2 require suspension of CORE ALTERATIONS if one required core subcritical neutron flux monitor or a required core subcritical neutron flux monitor audible count rate circuit, respectively, is inoperable in MODE 6. Required Action A.2 requires suspension of operations that would cause introduction into the reactor coolant system (RCS), coolant with boron concentration less than required to meet the boron concentration of TS 3.9.1.

PINGP Units 1 and 2 TS, Section 5.0, contains administrative controls. All of TS, Section 5.0, is within the scope of this amendment request.

2.3 Reason for the Proposed Changes Adopt TSTF-471 Suspending CORE ALTERATIONS has no effect on the initial conditions or mitigation of any Design Basis Accident (DBA) or transient, and these requirements apply an operational burden with no corresponding safety benefit.

Adopt TSTF-571-T TSTF-571-T addresses NRC staff concerns with TSTF-51, Revision 2, "Revise Containment Requirements during Handling Irradiated Fuel and Core Alterations,", TSTF-286, Revision 2, "Define 'Operations Involving Positive Reactivity Additions'," and TSTF-471.

Section 5.0 Page Numbering The proposed change revises the pagination scheme used in Section 5.0 from the current scheme where page numbers continue from subsection to subsection to a new scheme where Page 3 of 14

L-PI-21-007 NSPM Enclosure the page numbers reset with each subsection. Unused pages will also be removed. This administrative change will ease the implementation of future changes.

2.4 Description of the Proposed Changes TSTF-471 The proposed change eliminates the defined term CORE ALTERATIONS from PINGP TS and all uses of the term from the Specifications and Bases. This affects the following Specifications:

1.1, Definitions, definition of CORE ALTERATIONS eliminated 3.8.2, A.C. Sources - Shutdown, Require Actions A.1 and B.1 eliminated 3.8.5, D.C. Sources - Shutdown, Required Action B.1 eliminated 3.8.8, Inverters - Shutdown, Required Action A.1 eliminated 3.8.10, Distribution Systems - Shutdown, Required Action A.2.1 eliminated 3.9.1, Boron Concentration, Required Action A.1 eliminated 3.9.3, Nuclear Instrumentation, Required Action A.1 modified to replace CORE ALTERATIONS with positive reactivity additions; Required Action C.2 eliminated.

TSTF-571-T The proposed change revises TS 3.9.3, Required Action A.2 to add a note and revise the wording of the Required Action. The note provides an allowance to move fuel assemblies, sources, and reactivity control components if necessary to restore the inoperable core subcritical neutron flux monitor or to complete movement of a component to a safe condition.

The Required Action is modified to suspend movement of fuel, sources, and reactivity control components within the reactor vessel.

Section 5.0 Page Numbering The proposed change revises the Section 5.0 pagination scheme from the current scheme where pages numbers continue from subsection to subsection to a new scheme where the page numbers reset with each subsection. Unused pages will also be removed.

The Bases are revised as applicable to reflect the changes made. Attachment 1 to this Enclosure provides markups of the current TS. Attachment 3 of this Enclosure provides markups of the current TS Bases (for information).

3.0 TECHNICAL EVALUATION

3.1 Technical Evaluation of TSTF-471 The term core alteration does not appear in Title 10 of the Code of Federal Regulations.

Since CORE ALTERATIONS only occur when the reactor vessel head is removed, it only Page 4 of 14

L-PI-21-007 NSPM Enclosure applies in MODE 6. There are only two accidents considered during MODE 6 for PWRs: a fuel handling accident and a boron dilution accident. A fuel handling accident is initiated by the dropping of an irradiated fuel assembly, either in the containment or in the spent fuel pool.

There are no mitigation actions. Suspension of CORE ALTERATIONS, except for suspension of movement of irradiated fuel, will not prevent or impair the mitigation of a fuel handling accident.

The second analyzed event is a boron dilution accident. A boron dilution accident is initiated by a dilution source which results in the boron concentration dropping below that required to maintain the SHUTDOWN MARGIN. As described in the Bases of Specification 3.9.1, Boron Concentration, (which applies in MODE 6), The refueling boron concentration and associated shutdown margin limits are specified in the COLR. The required boron concentration will vary depending on time in core life. Plant procedures ensure the specified boron concentration in order to maintain an overall core reactivity of keff 0.95 during fuel handling, with control rods and fuel assemblies assumed to be in the most adverse configuration (least negative reactivity) allowed by plant procedures. The accident is mitigated by stopping the dilution.

Suspension of CORE ALTERATIONS has no effect on the mitigation of a boron dilution accident. Movement of control rods or fuel do not affect the initial conditions of a boron dilution accident as it is assumed that the control rods and fuel are in the most adverse conditions with a large safety margin (keff 0.95). To address the possibility of a misloaded fuel assembly in Technical Specification 3.9.3, a Required Action is added that suspends positive reactivity additions if nuclear instrumentation is not available. This precludes movement of fuel assemblies which could add reactivity to the core.

In summary, with the exception of suspending movement of irradiated fuel assemblies, there are no DBAs or transients that are initiated by or mitigation that is affected by suspension of CORE ALTERATIONS. Therefore, if all Required Actions that require suspension of CORE ALTERATIONS also require suspension of movement of irradiated fuel, suspension of CORE ALTERATIONS provides no safety benefit.

The term CORE ALTERATION is used in the following Specifications:

3.8.2, A.C. Sources - Shutdown 3.8.5, D.C. Sources - Shutdown 3.8.8, Inverters - Shutdown 3.8.10, Distribution Systems - Shutdown 3.9.1, Boron Concentration 3.9.3, Nuclear Instrumentation An analysis of elimination of the defined term CORE ALTERATIONS for each of these Specifications is given below.

TS 3.8.2, TS 3.8.5, TS 3.8.8, and TS 3.8.10 If a required train of electrical power (A.C, D.C, Inverters, or Distribution Systems) is inoperable, the Required Actions require:

Page 5 of 14

L-PI-21-007 NSPM Enclosure Suspension of CORE ALTERATIONS Suspension of movement of irradiated fuel assemblies, and Suspension of operations involving positive reactivity additions that could result in loss of required shutdown margin (SDM) or boron concentration.

As discussed above, because the Required Actions require the suspension of movement of irradiated fuel assemblies, the initiating conditions for a fuel handling accident are prohibited.

Because the Required Actions require the suspension of positive reactivity additions that could result in a loss of SDM, the initial conditions for a boron dilution accident are prevented.

Therefore, the action to suspend CORE ALTERATIONS provides no safety benefit and is not needed.

TS 3.9.1 If boron concentration is not within limit, the Required Actions require immediate suspension of CORE ALTERATIONS, immediate suspension of positive reactivity additions, and immediate actions to restore the boron concentration within limits. This Specification is only concerned with a boron dilution accident, as SDM has no bearing on a fuel handling accident. Note that the Required Action to suspend positive reactivity additions would also prohibit adding fuel assemblies to the reactor, which could reduce the SDM. The requirement to suspend positive reactivity additions is the only action needed to mitigate a boron dilution event. Therefore, the action to suspend CORE ALTERATIONS provides no safety benefit and is not needed.

TS 3.9.3, Required Actions A.1 and C.2 If a required core subcritical neutron flux monitor (source range detector) is inoperable, CORE ALTERATIONS must be suspended and operations that would cause introduction into the RCS, coolant with boron concentration less than required to meet the boron concentration of LCO 3.9.1. An inoperable source range detector has no effect on the initiation or mitigation of a fuel handling accident. Suspending introduction of RCS coolant at less than the required boron concentration prevents a boron dilution accident. Therefore, suspension of CORE ALTERATIONS does nothing to prevent any analyzed accident. It is a good practice to not move fuel with less than a full complement of source range detectors. Therefore, Required Action A.1 is revised to preclude positive reactivity additions. However, as stated in 10 CFR 50.36(b), The technical specifications will be derived from the analyses and evaluation included in the safety analysis report, and amendments thereto, submitted pursuant to § 50.34. Suspension of CORE ALTERATIONS in this circumstance is not based on the analyses in the safety analysis report and that Required Action is removed.

In addition, PINGP TS 3.9.3 includes Required Action C.2 to suspend CORE ALTERATIONS when the required core subcritical neutron flux monitor audible count rate circuit is inoperable.

Required Action C.2 is not part of standard TS and is proposed to be deleted consistent with the changes included in adopting TSTF-471 as well as NUREG-1431. This is acceptable because Condition C is included in PINGP TS to mitigate a postulated dilution accident.

Suspending CORE ALTERATIONS has no effect on the initial conditions or mitigation of a dilution accident. The LCO discussion in the PINGP Bases for TS 3.9.3 states, This LCO also Page 6 of 14

L-PI-21-007 NSPM Enclosure requires that one audible count rate circuit, associated with either N-31 or N-32, be OPERABLE to ensure that audible indication is available to alert the operator in containment in the event of a dilution accident or improperly loaded fuel assembly. However, the inclusion of a postulated improperly loaded fuel assembly in the discussion of the audible count rate circuit in this section is not consistent with the other sections of the PINGP TS 3.9.3 bases and is inconsistent with standard TS 3.9.3 bases, as well. Therefore, the action to suspend CORE ALTERATIONS provides no safety benefit and is not needed.

3.2 Technical Evaluation of TSTF-571-T The proposed change revises TS 3.9.3, Required Action A.2 with a note to add allowance to move fuel assemblies, sources, and reactivity control components if necessary to restore operability or to complete movement of a component to a safe condition. The Required Action is further modified to suspend movement of fuel, sources, and reactivity control components within the reactor vessel. The proposed changes to Required Action A.2 protect against inadvertent boron dilution resulting in a change in core reactivity that the remaining core subcritical neutron flux monitor could not detect.

NRC letter to the Technical Specification Task Force (TSTF) dated November 7, 2013, (Reference 4) described NRC staff concerns with the following TSTF travelers:

TSTF-51, Revision 2, Revise Containment Requirements During Handling Irradiated Fuel and Core Alterations, TSTF-286, Revision 2, Operations Involving Positive Reactivity Additions, and TSTF-471, Revision 1, Eliminate Use of Term Core Alterations in Actions and Notes,"

NRC letter to the TSTF dated October 4, 2018, (Reference 7) provides the resolution of the concerns in terms of concerns with TSTF-286 and concerns with TSTF-51 and TSTF-471.

TSTF-286 Concerns and Resolution. Reference 7 concludes that, if a licensee includes the changes of traveler TSTF-571-T when adopting TSTF-286, the NRC staffs technical concerns should be adequately addressed regarding TSTF-286. NSPM previously adopted TSTF-286 in PINGP TS with the conversion to improved standard TS in Unit 1 and Unit 2 Amendments 158 and 149 (Reference 5). Thus, NSPM proposes to adopt TSTF-571-T as part of the proposed amendment to address the NRC staff concern.

TSTF-51 and TSTF-471 Concerns and Resolution. Reference 7 notes that for certain facilities, LARs adopting TSTF-51 and TSTF-471 could result in exceeding the bounding licensing basis Fuel Handling Accident analysis of record dose for control room. NSPM previously adopted, in part, TSTF-51 in PINGP TS with conversion to improved standard TS (Reference 5).

Under Amendments 166 and 156 (Reference 6), NSPM adopted a portion of TSTF-51 and selectively implemented alternate source term. This included using the TSTF-51 definition of recently irradiated and changes to TS 3.3.5, Containment Ventilation Isolation Instrumentation, and TS 3.9.4, Containment Penetrations (at that time). In Reference 7, the NRC reminded Page 7 of 14

L-PI-21-007 NSPM Enclosure licensees that an associated LAR should include information as described in the TSTF-51 Reviewers Note. NSPM committed to the guidelines of TSTF-51 Reviewers Note for the assessment of systems removed from service during movement of irradiated fuel at PINGP in the license amendment request for Amendments 166 and 156. Therefore, this concern has been addressed in previous approved licensing action.

Reference 7 also requested a specific discussion for any TS limiting condition for operation (LCO) which is proposed to be revised to remove the term CORE ALTERATIONS from LCO applicability. This LAR does not include removal of the term CORE ALTERATIONS from any Applicability statement, because the current PINGP TS include no Applicability statements in which the term CORE ALTERATIONS appears.

TS 3.9.3, Required Action A.2 The proposed change revises Required Action A.2 of TS 3.9.3 when a required core subcritical neutron flux monitor is inoperable. The proposed Required Action A.1 for TSTF-471, described above, requires immediately suspending positive reactivity additions. This action prohibits diluting the boron concentration of the coolant in the RCS, the loading of fuel assemblies or sources into the core, or the removal of reactivity control components.

The existing Required Action A.2, which prohibits introducing coolant into the RCS unless that coolant has a boron concentration greater than or equal to the boron concentration limit in LCO 3.9.1, is deleted. This action would allow dilution of the boron concentration in the RCS with one core subcritical neutron flux monitor inoperable provided the boron concentration is not reduced to less than the limit in LCO 3.9.1. Thus, removal of this action addresses the NRC staff concern that an inadvertent boron dilution could occur and the change in core reactivity may not be detected due to the inoperable core subcritical neutron flux monitor. With the removal of current Required Action A.2, the proposed Required Action A.1 would prohibit any dilution of the RCS, even if the introduced coolant has a boron concentration greater than the limit in LCO 3.9.1.

The proposed Required Action A.2 would also prohibit any movement of fuel, sources, or reactivity control components in the reactor core. With one core subcritical neutron flux monitor inoperable, the operator may not be able to monitor the core reactivity condition in part of the reactor. Therefore, the conservative action is to suspend movement of any core components that may affect reactivity until the core subcritical neutron flux monitor is restored. While unlikely, movement of fuel assemblies from one core location to another, the movement of sources, or the removal of reactivity control components, could result in an undetected change in core reactivity.

The proposed Required Action A.2 is modified by a Note that permits fuel assemblies, sources, and reactivity control components to be moved if necessary to restore an inoperable core neutron flux monitor or to complete movement of a component to a safe condition. The core subcritical neutron flux monitors are located outside the reactor core. Troubleshooting, repair, or replacement of the inoperable core subcritical neutron flux monitor may require moving fuel, sources, or reactivity control components away from the core subcritical neutron flux monitor Page 8 of 14

L-PI-21-007 NSPM Enclosure location to minimize the radiation dose to the workers. If a fuel assembly, source, or reactivity control component is in the process of being moved when it is discovered that a required core subcritical neutron flux monitor is inoperable, the component may be placed in a safe condition.

3.3 Technical Evaluation of Administrative Change to TS 5.0 Page Numbering This change is purely administrative and changes none of the requirements in Section 5.0.

3.4 Variations NSPM proposes no variations from TS changes described in TSTF-571-T and is proposing the following variations from the TS changes described in the TSTF-471. These variations do not affect the applicability of TSTF-471.

The TSTF-471 markup of NUREG-1431 standard TS 3.8.2 eliminated CORE ALTERATIONS by deleting Required Action A.2.1. The corresponding PINGP TS 3.8.2, Required Action to be deleted is Required Action A.1.

The TSTF-471 markup of NUREG-1431 standard TS 3.8.5 eliminated CORE ALTERATIONS by deleting Required Action B.2.1. The corresponding PINGP TS 3.8.5, Required Action to be deleted is Required Action B.1.

The TSTF-471 markup of NUREG-1431 standard TS 3.8.8 eliminated CORE ALTERATIONS by deleting Required Action A.2.1. The corresponding PINGP TS 3.8.8, Required Action to be deleted is Required Action A.1.

PINGP TS 3.9.3, Required Action C.2 to suspend CORE ALTERATIONS when a required core subcritical neutron flux monitor audible count rate circuit is inoperable is a PINGP-specific Required Action that is not part of NUREG-1431 standard TS.

PINGP TS do not include an LCO 3.9.2 for Unborated Water Source Isolation Valves.

Therefore, the proposed change to that section of the Westinghouse Owners Group (WOG)

Standard Technical Specifications (STS) proposed in TSTF-471 does not apply to PINPG and is not included in this amendment request.

The Travelers discuss the applicable regulatory requirements and guidance, including the 10 CFR 50, Appendix A, General Design Criteria (GDC). PINGP was not licensed to the 10 CFR 50, Appendix A, GDC. The PINGP was designed and constructed to comply with NSPs understanding of the intent of the AEC General Design Criteria (AEC GDC) for Nuclear Power Plant Construction Permits, as proposed on July 10, 1967. Since the construction of the plant was significantly completed prior to the issuance of the February 20, 1971, 10CFR50, Appendix A GDC, the plant was not reanalyzed and the Final Safety Analysis Report (FSAR) was not revised to reflect these later criteria. However, the AEC Safety Evaluation Report acknowledged that the AEC staff assessed the plant, as described in the FSAR, against the Appendix A design criteria and ... are satisfied that the plant design generally conforms to the intent of these criteria. This difference does not alter the conclusion that the proposed change is applicable to PINGP.

4.0 REGULATORY EVALUATION

4.1 Applicable Regulatory Requirements/Criteria The TSs satisfy 10 CFR 50.36, "Technical specifications." The following systems and parameters meet one or more of the criteria of 10 CFR 50.36(c)(2)(ii):

AC sources, DC sources, inverters, and distribution systems in MODES 5 or 6 or during movement of irradiated fuel assemblies.

Boron concentration requirement in Mode 6, and Neutron instrumentation requirements in Mode 6.

The proposed amendment continues to provide appropriate remedial actions and shutdown requirements required by 10 CFR 50.36(c)(2)(i) for any system requiring an LCO pursuant the criteria of 10 CFR 50.36(c)(2)(ii).

The following AEC GDC are applicable to the change:

GDC 13: Fission Process Monitors and Controls. The proposed amendment does not change means provided for monitoring the fission, determining control rod position, control and determination of boron concentration.

GDC 19: Protection Systems Reliability. The proposed amendment does not change the design of protection systems.

GDC 27: Redundancy of Reactivity Control. The proposed amendment will not change the two independent reactivity control systems, rod cluster control assemblies and boric acid dissolved in the reactor coolant.

GDC 29: Reactivity Shutdown Capability. The proposed amendment will not change that the reactor may be made subcritical by the rod cluster control system sufficiently fast to prevent exceeding acceptable fuel damage limits, under all anticipated conditions even with the most reactive rod control cluster fully withdrawn.

GDC 31: Reactivity Control Systems Malfunction. The proposed amendment will not change the reactivity control systems or their ability to ensure acceptable fuel damage limits are not exceeded even in the event of a single malfunction of either system.

GDC 39: Emergency Power for Engineered Safety Features. The proposed amendment will not change the independent connections to the system grid or the redundant source of emergency power from the four diesel generators installed at PINGP. Power to the engineered safety features will still be assured even with the failure of a single active component in each system.

The proposed change does not affect compliance with these regulations and guidance and will insure that the lowest functional capabilities or performance levels of equipment required for safe operation are met.

Page 10 of 14

L-PI-21-007 NSPM Enclosure 4.2 Precedent STS traveler TSTF-471 was approved for use by the NRC staff and incorporated into the applicable Standard TS NUREGs, Revision 4, published in April 2012. Some facilities have adopted, as technically practicable, TSTF-471. For example:

Calvert Cliffs Nuclear Power Plant, Units 1 and 2, Amendments 279 and 256.

Point Beach Nuclear Plant, Units 1 and 2, Amendments 224 and 230.

4.3 No Significant Hazard Consideration Analysis NSPM requests adoption of TSTF-471, "Eliminate Use of the Term CORE ALTERATIONS in ACTIONS and Notes," which is an approved change to the Standard Technical Specifications, into the PINGP Units 1 and 2 Technical Specifications (TS). This proposed change eliminates the defined term CORE ALTERATIONS and all uses of the term from the TS and Bases.

NSPM also requests adoption of TSTF-571-T,Revise Actions for Inoperable Source Range Neutron Flux Monitor, into the PINGP Units 1 and 2 TS. This proposed change to TS 3.9.3 ensures that no actions are taken that could alter the core reactivity when a required core subcritical neutron flux monitor is inoperable. NSPM further proposes an administrative change to reformat the page numbering of TS Section 5.0 and remove unused pages for ease of future changes.

NSPM 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 change to adopt TSTF-471 eliminates the use of the term CORE ALTERATIONS from TS and all Required Actions requiring suspension of CORE ALTERATIONS. CORE ALTERATIONS are not an initiator of any accident previously evaluated except a fuel handling accident. Those revised Specifications which protect the initial conditions of a fuel handling accident also require the suspension of movement of irradiated fuel assemblies. This Required Action protects the initial conditions of a fuel handling accident and, therefore, suspension of CORE ALTERATIONS is not required. Suspension of CORE ALTERATIONS does not provide mitigation of any accident previously evaluated. Therefore, CORE ALTERATIONS do not affect the initiators of the accidents previously evaluated and suspension of CORE ALTERATIONS does not affect the mitigation of the accidents previously evaluated.

The proposed change to adopt TSTF-571-T revises the Required Action for an inoperable core subcritical neutron flux monitor to suspend the movement of fuel, sources, and reactivity control components within the reactor vessel. The Actions taken Page 11 of 14

L-PI-21-007 NSPM Enclosure when a required core subcritical neutron flux monitor is inoperable are not initiators to any accident previously evaluated. The core subcritical neutron flux monitors are credited for detecting a boron dilution accident. The proposed change restricts the licensee's actions while a required core subcritical neutron flux monitor is inoperable beyond the current requirements, further preventing the occurrence of a boron dilution accident. Therefore, the consequences of an accident previously evaluated are not significantly increased.

The proposed administrative change to TS 5.0 page numbering and unused page removal has no impact on probability or consequences of accidents.

Therefore, the proposed changes do 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 previously evaluated?

Response: No No new or different accidents result from utilizing the proposed changes of TSTF-471 and TSTF-571-T. The changes do not involve a physical alteration of the plant (i.e., no new or different type of equipment will be installed) or a significant change in the methods governing normal plant operation. In addition, the changes do not impose any new or different requirements. The changes do not alter assumptions made in the safety analysis. The proposed changes are consistent with the safety analysis assumptions.

The proposed administrative change to TS 5.0 page numbering and unused page removal has no impact on the content of TS 5.0, the plant, or plant operation; nor does it change any requirements in TS 5.0.

Therefore, the proposed changes do 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 Only two accidents are postulated to occur in the plant conditions in which CORE ALTERATIONS may be made: a fuel handling accident and a boron dilution accident.

The proposed change to adopt TSTF-471 and suspending movement of irradiated fuel assemblies prevents a fuel handling accident. Also requiring the suspension of CORE ALTERATIONS is an overly broad, redundant requirement that does not increase the margin of safety. CORE ALTERATIONS have no effect on a boron dilution accident.

Core components are not involved in the creation or mitigation of a boron dilution accident and the SHUTDOWN MARGIN limit is based on assuming the worst-case Page 12 of 14

L-PI-21-007 NSPM Enclosure configuration of the core components. Therefore, CORE ALTERATIONS have no effect on the margin of safety related to a boron dilution accident.

The proposed adoption of TSTF-571-T revises the Required Actions for an inoperable core subcritical neutron flux monitor to prohibit the movement of fuel assemblies, sources, and reactivity control components when a required core subcritical neutron flux monitor is inoperable. No safety limits are affected. No Limiting Conditions for Operation or Surveillance limits are affected. The design, operation, surveillance methods, and acceptance criteria specified in applicable codes and standards (or alternatives approved for use by the NRC) will continue to be met as described in the plants licensing basis. The proposed change does not adversely affect existing plant safety margins or the reliability of the equipment assumed to operate in the safety analysis. As such, there are no changes being made to safety analysis assumptions, safety limits, or limiting safety system settings that would adversely affect plant safety.

The proposed administrative change to TS 5.0 page numbering and unused page removal has no impact on the content of TS 5.0 and results in no change to margin of safety.

Therefore, the proposed changes do not involve a significant reduction in a margin of safety.

Based on the above, NSPM concludes that the proposed amendment presents no 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.

4.4 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 Commissions 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 EVALUATION The proposed change 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 change does not involve (i) a significant hazards consideration, (ii) a significant change in the types or 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 change 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 change.

Structural integrity performance criterion: All in-service steam generator tubes shall retain structural integrity over the full range of normal operating conditions (including startup, operation in the power range, hot standby, and cool down), all anticipated transients included in the design specification, and design basis accidents. This includes retaining a safety factor of 3.0 against burst under normal steady state full power operation primary-to-secondary pressure differential and a safety factor of 1.4 against burst applied to the design basis accident primary-to-secondary pressure differentials. Apart from the above requirements, additional loading conditions associated with the design basis accidents, or combination of accidents in accordance with the design and licensing basis, shall also be evaluated to determine if the associated loads contribute significantly to burst or collapse.

Programs and Manuals 5.5 5.5 Programs and Manuals 5.5.8 Steam Generator (SG) Program (continued)

In the assessment of tube integrity, those loads that do significantly affect burst or collapse shall be determined and assessed in combination with the loads due to pressure with a safety factor of 1.2 on the combined primary loads and 1.0 on axial secondary loads.

2. Accident induced leakage performance criterion: The primary to secondary accident induced leakage rate for any design basis accident, other than a SG tube rupture, shall not exceed the leakage rate assumed in the accident analysis in terms of total leakage rate for all SGs and leakage rate for an individual SG. Leakage is not to exceed 1 gpm per SG.
3. The operational LEAKAGE performance criterion is specified in LCO 3.4.14, RCS Operational LEAKAGE.
c. Provisions for SG tube plugging criteria. Tubes found by inservice inspection to contain flaws with a depth equal to or exceeding 40% of the nominal tube wall thickness shall be plugged.
d. Provisions for SG tube inspections. Periodic SG tube inspections shall be performed. The number and portions of the tubes inspected and methods of inspection shall be performed with the objective of detecting flaws of any type (e.g., volumetric flaws, axial and circumferential cracks) that may be present along the length of the tube, from the tube-to-tubesheet weld at the tube inlet to the tube-to-tubesheet weld at the tube outlet, and that may satisfy the applicable tube plugging criteria. The tube-to-tubesheet weld is not part of the tube. In addition to meeting the requirements of d.1, d.2 and d.3 below, the inspection scope, inspection methods, and inspection intervals shall be such as to ensure that SG tube integrity is maintained until the next SG inspection. A degradation assessment shall be 5.5-8 Prairie Island Unit 1 - Amendment No. 158 177 208 Units 1 and 2 5.0-14 Unit 2 - Amendment No. 149 167 195

Programs and Manuals 5.5 5.5 Programs and Manuals 5.5.8 Steam Generator (SG) Program (continued) performed to determine the type and location of flaws to which the tubes may be susceptible and, based on this assessment, to determine which inspection methods need to be employed and at what locations.

1. Inspect 100% of the tubes in each SG during the first refueling outage following SG installation.
2. After the first refueling outage following SG installation, inspect each SG at least every 72 effective full power months or at least every third refueling outage (whichever results in more frequent inspections). In addition, the minimum number of tubes inspected at each scheduled inspection shall be the number of tubes in all SGs divided by the number of SG inspection outages scheduled in each inspection period as defined in a, b, c and d below. If a degradation assessment indicates the potential for a type of degradation to occur at a location not previously inspected with a technique capable of detecting this type of degradation at this location and that may satisfy the applicable tube plugging criteria, the minimum number of locations inspected with such a capable inspection technique during the remainder of the inspection period may be prorated. The fraction of locations to be inspected for this potential type of degradation at this location at the end of the inspection period shall be no less than the ratio of the number of times the SG is scheduled to be inspected in the inspection period after the determination that a new form of degradation could potentially be occurring at this location divided by the total number of times the SG is scheduled to be inspected in the inspection period. Each inspection period defined below may be extended up to 3 effective full power months to include a SG inspection outage in an inspection period and the subsequent inspection period begins at the conclusion of the included SG inspection outage.

a) After the first refueling outage following SG installation, inspect 100% of the tubes during the next 144 effective full power months. This constitutes the first inspection period; 5.5-9 Prairie Island Unit 1 - Amendment No. 158 177 208 Units 1 and 2 5.0-15 Unit 2 - Amendment No. 149 167 195

Programs and Manuals 5.5 5.5 Programs and Manuals 5.5.8 Steam Generator (SG) Program (continued) b) During the next 120 effective full power months, inspect 100% of the tubes. This constitutes the second inspection period; c) During the next 96 effective full power months, inspect 100% of the tubes. This constitutes the third inspection period; and d) During the remaining life of the SGs, inspect 100% of the tubes every 72 effective full power months. This constitutes the fourth and subsequent inspection periods.

3. If crack indications are found in any SG tube, then the next inspection for each affected and potentially affected SG for the degradation mechanism that caused the crack indication shall not exceed 24 effective full power months or one refueling outage (whichever results in more frequent inspections). If definitive information, such as from examination of a pulled tube, diagnostic non-destructive testing, or engineering evaluation indicates that a crack-like indication is not associated with a crack(s), then the indication need not be treated as a crack.
e. Provisions for monitoring operational primary to secondary LEAKAGE.

a. Provisions for condition monitoring assessments. Condition monitoring assessment means an evaluation of the as found condition of the tubing with respect to the performance criteria for structural integrity and accident induced leakage. The as found condition refers to the condition of the tubing during an SG inspection outage, as determined from the inservice inspection results or by other means, prior to the plugging of tubes. Condition monitoring assessments shall be conducted during each outage during which the SG tubes are inspected or plugged to confirm that the performance criteria are being met.
b. Performance criteria for SG tube integrity. SG tube integrity shall be maintained by meeting the performance criteria for tube structural integrity, accident induced leakage, and operational LEAKAGE.
1. Structural integrity performance criterion: All in-service steam generator tubes shall retain structural integrity over the full range of normal operating conditions (including startup, operation in the power range, hot standby, and cool down), all anticipated transients included in the design specification, and design basis accidents. This includes retaining a safety factor of 3.0 against burst under normal steady state full power operation primary-to-secondary pressure differential and a safety factor of 1.4 against burst applied to the design basis accident primary-to-secondary pressure differentials. Apart from the above requirements, additional loading conditions associated with the design basis accidents, or combination of accidents in accordance with the design and licensing basis, shall also be evaluated to determine if the associated loads contribute significantly to burst or collapse.

In the assessment of tube integrity, those loads that do significantly affect burst or collapse shall be determined and assessed in combination with the loads due to pressure with a safety factor of 1.2 on the combined primary loads and 1.0 on axial secondary loads.

2. Accident induced leakage performance criterion: The primary to secondary accident induced leakage rate for any design basis accident, other than a SG tube rupture, shall not exceed the leakage rate assumed in the accident analysis in terms of total leakage rate for all SGs and leakage rate for an individual SG. Leakage is not to exceed 1 gpm per SG.
3. The operational LEAKAGE performance criterion is specified in LCO 3.4.14, RCS Operational LEAKAGE.
c. Provisions for SG tube plugging criteria. Tubes found by inservice inspection to contain flaws with a depth equal to or exceeding 40% of the nominal tube wall thickness shall be plugged.
d. Provisions for SG tube inspections. Periodic SG tube inspections shall be performed. The number and portions of the tubes inspected and methods of inspection shall be performed with the objective of detecting flaws of any type (e.g., volumetric flaws, axial and circumferential cracks) that may be present along the length of the tube, from the tube-to-tubesheet weld at the tube inlet to the tube-to-tubesheet weld at the tube outlet, and that may satisfy the applicable tube plugging criteria. The tube-to-tubesheet weld is not part of the tube. In addition to meeting the requirements of d.1, d.2 and d.3 below, the inspection scope, inspection methods, and inspection intervals shall be such as to ensure that SG tube integrity is maintained until the next SG inspection.

1. Inspect 100% of the tubes in each SG during the first refueling outage following SG installation.
2. After the first refueling outage following SG installation, inspect each SG at least every 72 effective full power months or at least every third refueling outage (whichever results in more frequent inspections). In addition, the minimum number of tubes inspected at each scheduled inspection shall be the number of tubes in all SGs divided by the number of SG inspection outages scheduled in each inspection period as defined in a, b, c and d below. If a degradation assessment indicates the potential for a type of degradation to occur at a location not previously inspected with a technique capable of detecting this type of degradation at this location and that may satisfy the applicable tube plugging criteria, the minimum number of locations inspected with such a capable inspection technique during the remainder of the inspection period may be prorated. The fraction of locations to be inspected for this potential type of degradation at this location at the end of the inspection period shall be no less than the ratio of the number of times the SG is scheduled to be inspected in the inspection period after the determination that a new form of degradation could potentially be occurring at this location divided by the total number of times the SG is scheduled to be inspected in the inspection period. Each inspection period defined below may be extended up to 3 effective full power months to include a SG inspection outage in an inspection period and the subsequent inspection period begins at the conclusion of the included SG inspection outage.

a) After the first refueling outage following SG installation, inspect 100% of the tubes during the next 144 effective full power months. This constitutes the first inspection period; Prairie Island Unit 1 - Amendment No. TBD Units 1 and 2 5.5-9 Unit 2 - Amendment No. TBD

FOR INFORMATION ONLY (11 Pages Follow)

AC Sources-Shutdown B 3.8.2 BASES APPLICABILITY d. Instrumentation and control capability is available for (continued) monitoring and maintaining the unit in a cold shutdown condition or refueling condition.

The AC power requirements for MODES 1, 2, 3, and 4 are covered in LCO 3.8.1.

The Load Sequencer requirements are covered in LCO 3.3.4, 4 kV Safeguards Bus Voltage Instrumentation.

ACTIONS LCO 3.0.3 is not applicable while in MODE 5 or 6. However, since irradiated fuel assembly movement can occur in MODE 1, 2, 3, or 4, the ACTIONS have been modified by a Note stating that LCO 3.0.3 is not applicable. If moving irradiated fuel assemblies while in MODE 5 or 6, LCO 3.0.3 would not specify any action. If moving irradiated fuel assemblies while in MODE 1, 2, 3, or 4, the fuel movement is independent of reactor operations. Entering LCO 3.0.3 while in MODES 1, 2, 3, or 4 would require the unit to be shutdown unnecessarily.

and A.1, A.2, A.3, A.4, B.1, B.2, B.3, and B.4 A required path would be considered inoperable if it were not available to at least one required Safeguards train. Although two trains may be required by LCO 3.8.10, the one train with offsite power available may be capable of supporting sufficient required features to allow continuation of CORE ALTERATIONS and fuel movement.

Prairie Island Units 1 and 2 B 3.8.2-5 Revision 242

AC Sources-Shutdown B 3.8.2 and BASES ACTIONS A.1, A.2, A.3, A.4, B.1, B.2, B.3, and B.4 (continued)

With the required DG inoperable, the minimum required diversity of AC power sources is not available. It is, therefore, required to suspend CORE ALTERATIONS, movement of irradiated fuel assemblies, and operations involving positive reactivity additions that could result in loss of required SDM (MODE 5) or boron concentration (MODE 6). Suspending positive reactivity additions that could result in failure to meet the minimum SDM or boron concentration limit is required to assure continued safe operation.

Introduction of coolant inventory must be from sources that have a boron concentration greater than that required in the RCS for minimum SDM or refueling boron concentration. This may result in an overall reduction in RCS boron concentration, but provides acceptable margin to maintaining subcritical operation. Introduction of temperature changes including temperature increases when operating with a positive MTC must also be evaluated to ensure they do not result in a loss of required SDM.

Suspension of these activities does not preclude completion of actions to establish a safe conservative condition. These actions minimize the probability of the occurrence of postulated events. It is further required to immediately initiate action to restore the required AC sources and to continue this action until restoration is accomplished in order to provide the necessary AC power to the unit safety systems.

The Completion Time of immediately is consistent with the required times for actions requiring prompt attention. The restoration of the required AC electrical power sources should be completed as quickly as possible in order to minimize the time during which the unit safety systems may be without sufficient power.

Prairie Island Units 1 and 2 B 3.8.2-6 Revision 242

DC Sources - Shutdown B 3.8.5 BASES ACTIONS A.1 (continued)

Condition A represents one train with one required battery charger inoperable (e.g., the voltage limit of SR 3.8.4.1 is not maintained).

Required Action A.1 limits the restoration time for the inoperable battery charger to 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />. The 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> Completion Time reflects a reasonable time to effect restoration of the qualified battery charger to OPERABLE status.

and B.1, B.2, B.3, and B.4 Condition B represents one train with one required DC electrical power subsystem inoperable for reasons other than Condition A or if the Required Actions and associated Completion Time of Condition A are not met. In this Condition there may not be adequate DC power available to support the subsystems required by LCO 3.8.10.

Therefore, conservative actions are required (i.e., to suspend CORE ALTERATIONS, movement of irradiated fuel assemblies, and operations involving positive reactivity additions) that assure the minimum SDM or boron concentration limit is met to assure continued safe operation. Introduction of coolant inventory must be from sources that have a boron concentration greater than that required in the RCS for minimum SDM or refueling boron concentration. This may result in an overall reduction in RCS boron concentration, but provides acceptable margin to maintaining subcritical operation. Introduction of temperature changes including temperature increases when operating with a positive MTC must also be evaluated to ensure they do not result in a loss of required SDM.

Prairie Island Units 1 and 2 B 3.8.5-6 Revision 242

Inverters-Shutdown B 3.8.8 BASES APPLICABILITY d. Instrumentation and control capability is available (continued) for monitoring and maintaining the unit in a cold shutdown condition or refueling condition.

Inverter requirements for MODES 1, 2, 3, and 4 are covered in LCO 3.8.7.

ACTIONS LCO 3.0.3 is not applicable while in MODES 5 and 6. However, since irradiated fuel assembly movement can occur in MODE 1, 2, 3, or 4, the ACTIONS have been modified by a Note stating that LCO 3.0.3 is not applicable. If moving irradiated fuel assemblies while in MODE 5 or 6, LCO 3.0.3 would not specify any action. If moving irradiated fuel assemblies while in MODE 1, 2, 3, or 4, the fuel movement is independent of reactor operations. Entering LCO 3.0.3 while in MODE 1, 2, 3, or 4 would require the unit to be shutdown unnecessarily.

and A.1, A.2, A.3, and A.4 If the required inverter is inoperable, the remaining OPERABLE Reactor Protection Instrument AC panel power supplies as required by LCO 3.8.10, Distribution Systems-Shutdown, may be capable of supporting sufficient required features to allow continuation of CORE ALTERATIONS, fuel movement, or operations with a potential for positive reactivity additions. Therefore, the allowance for sufficiently conservative actions is made (i.e., to suspend CORE ALTERATIONS, movement of irradiated fuel assemblies, and operations involving positive reactivity additions that could result in loss of required SDM (MODE 5) or boron concentration (MODE 6)).

Prairie Island Units 1 and 2 B 3.8.8-4 Revision 242

Distribution Systems-Shutdown B 3.8.10 BASES APPLICABILITY The safeguards AC, DC, and Reactor Protection Instrument AC (continued) electrical power distribution subsystems requirements for MODES 1, 2, 3, and 4 are covered in LCO 3.8.9 ACTIONS LCO 3.0.3 is not applicable while in MODES 5 and 6. However, since irradiated fuel assembly movement can occur in MODE 1, 2, 3, or 4, the ACTIONS have been modified by a Note stating that LCO 3.0.3 is not applicable. If moving irradiated fuel assemblies while in MODE 5 or 6, LCO 3.0.3 would not specify any action. If moving irradiated fuel assemblies while in MODE 1, 2, 3, or 4, the fuel movement is independent of reactor operations. Entering LCO 3.0.3 while in MODE 1, 2, 3, or 4 would require the unit to be shutdown unnecessarily.

and A.1, A.2.1, A.2.2, A.2.3, A.2.4, and A.2.5 Although redundant required features may require redundant trains of electrical power distribution subsystems to be OPERABLE, one OPERABLE distribution subsystem train may be capable of supporting sufficient required features to allow continuation of CORE ALTERATIONS and fuel movement. By allowing the option to declare required features associated with an inoperable distribution subsystem inoperable, appropriate restrictions are implemented in accordance with the affected distribution subsystem LCO's Required Actions. In many instances, this option may involve undesired administrative efforts. Therefore, the allowance for sufficiently conservative actions is made (i.e., to suspend CORE ALTERATIONS, movement of irradiated fuel assemblies, and operations involving positive reactivity additions that could result in loss of required SDM (MODE 5) or boron concentration (MODE 6)). Suspending positive reactivity additions that could result in failure to meet the minimum boron concentration limit is required to Prairie Island Units 1 and 2 B 3.8.10-5 Revision 242

Boron Concentration B 3.9.1 BASES APPLICABLE The RCS boron concentration satisfies Criterion 2 of SAFETY 10 CFR 50.36 (c)(2)(ii).

ANALYSES (continued)

LCO The LCO requires that a minimum boron concentration be maintained in the RCS and the refueling cavity while in MODE 6.

The boron concentration limits specified in the COLR ensure that a core keff of d 0.95 or other lower value is maintained during fuel handling operations. Violation of the LCO could lead to an inadvertent criticality during MODE 6.

APPLICABILITY This LCO is applicable in MODE 6 to ensure that the fuel in the reactor vessel will remain subcritical. The required boron concentration ensures a keff of d 0.95 or a lower value based on the dilution analysis. Above MODE 6, LCO 3.1.1, SHUTDOWN MARGIN (SDM) ensures that an adequate amount of negative reactivity is available to shut down the reactor and maintain it subcritical.

The Applicability is modified by a Note. The Note states that the limits on boron concentration are only applicable to the refueling cavity when connected to the RCS. When the refueling cavity is isolated from the RCS, no potential path for boron dilution exists.

ACTIONS A.1 and A.2 Continuation of CORE ALTERATIONS or positive reactivity additions (including actions to reduce boron concentration) is contingent upon maintaining the unit in compliance with the LCO.

If the boron concentration of any coolant volume in the RCS or the refueling cavity, when connected, is less than that needed to maintain shutdown margin within its limit, all operations involving CORE ALTERATIONS or positive reactivity additions must be Prairie Island Units 1 and 2 B 3.9.1-3 Revision 242

Boron Concentration B 3.9.1 BASES ACTIONS A.1 and A.2 (continued) suspended immediately.

Suspension of CORE ALTERATIONS and positive reactivity additions shall not preclude moving a component to a safe position.

Operations that individually add limited positive reactivity (e.g.,

temperature fluctuations from inventory addition or temperature control fluctuations), but when combined with all other operations affecting core reactivity (e.g., intentional boration) result in overall net negative reactivity addition, are not precluded by this action.

A.3 2 In addition to immediately suspending CORE ALTERATIONS and positive reactivity additions, boration to restore the concentration must be initiated immediately.

In determining the required combination of boration flow rate and concentration, no unique Design Basis Event must be satisfied. The only requirement is to restore the boron concentration to its required value as soon as possible. In order to raise the boron concentration as soon as possible, the operator should begin boration with the best source available for unit conditions.

Once actions have been initiated, they must be continued until the boron concentration is restored. The restoration time depends on the amount of boron that must be injected to reach the required concentration.

Prairie Island Units 1 and 2 B 3.9.1-4 Revision 242

Nuclear Instrumentation B 3.9.3 BASES (continued)

LCO This LCO requires that two core subcritical neutron flux monitors, capable of monitoring subcritical neutron flux, be OPERABLE to ensure that redundant monitoring capability is available to detect changes in core reactivity. Neutron detectors N-31, N-32, N-51 and N-52 may be used to satisfy this LCO requirement.

This LCO also requires that one audible countrate circuit, associated with either N-31 or N-32, be OPERABLE to ensure that audible indication is available to alert the operator in containment in the event of a dilution accident or improperly loaded fuel assembly.

APPLICABILITY In MODE 6, the core subcritical neutron flux monitors must be OPERABLE to determine changes in core reactivity. There are no other direct means available to check core reactivity levels. In MODES 2, 3, 4, and 5, the installed detectors and circuitry are also required to be OPERABLE by LCO 3.3.1, Reactor Trip System (RTS) Instrumentation.

positive reactivity additions and movement of fuel, sources, and reactivity control ACTIONS A1 and A.2 components within the reactor vessel With only one required core subcritical neutron flux monitor OPERABLE, redundancy has been lost. Since these instruments are the only direct means of monitoring core reactivity conditions, CORE ALTERATIONS and introduction of coolant into the RCS with boron concentration less than required to meet the minimum boron concentration of LCO 3.9.1 must be suspended immediately.

Suspending the introduction of coolant into the RCS with boron concentration less than required to meet the minimum boron concentration of LCO 3.9.1 is required to assure continued safe operation. Introduction of coolant inventory must be from sources that have a boron concentration greater than that required in the RCS for minimum SDM or refueling boron concentration. This may result in an overall reduction in RCS boron concentration, but provides acceptable margin to maintaining subcritical operation.

Prairie Island Units 1 and 2 B 3.9.3-2 Revision 242

Nuclear Instrumentation B 3.9.3 BASES ACTIONS A.1 and A.2 (continued)

Introduction of temperature changes, including temperature increases when operating with a positive moderator temperature coefficient (MTC), must also be evaluated to not result in reducing SDM below the required value. Performance of Required Action A.1 shall not preclude completion of movement of a component to a safe position.

Insert A B.1 With no required core subcritical neutron flux monitor OPERABLE, action to restore a monitor to OPERABLE status shall be initiated immediately. Once initiated, action shall be continued until a required core subcritical neutron flux monitor is restored to OPERABLE status.

B.2 With no required core subcritical neutron flux monitor OPERABLE, there are no direct means of detecting changes in core reactivity.

However, since CORE ALTERATIONS and positive reactivity additions that could lead to reducing SDM below the required value are not to be made, the core reactivity condition is stabilized until the core subcritical neutron flux monitors are OPERABLE. This stabilized condition is determined by performing SR 3.9.1.1 to ensure that the required boron concentration exists.

The Completion Time of once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> is sufficient to obtain and analyze a reactor coolant sample for boron concentration and ensures that unplanned changes in boron concentration would be identified. The 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> Frequency is reasonable, considering the low probability of a change in core reactivity during this time period.

Prairie Island Units 1 and 2 B 3.9.3-3 Revision 242

Insert A Suspending the movement of fuel, sources, and reactivity control components ensures that positive reactivity is not inadvertently added to the reactor core while the source range neutron flux monitor is inoperable. Required Action A.2 is modified by a Note that states that fuel assemblies, sources, and reactivity control components may be moved if necessary to facilitate repair or replacement of the inoperable source range neutron flux monitor. It may be necessary to move these items away from the locations in the core close to the source range neutron flux monitor to minimize personnel radiation dose during troubleshooting or repair. The Note also permits completion of movement of a component to a safe position, should the source range neutron flux monitor be discovered inoperable during component movement.

Nuclear Instrumentation B 3.9.3 BASES ACTIONS C.1 and C2 (continued)

With no audible core subcritical neutron flux monitor count rate circuit OPERABLE, only visual indication is available and prompt and definite indication of a boron dilution event would be lost. In this situation, the boron dilution event may not be detected quickly enough to assure sufficient time is available for operators to manually isolate the unborated water source and stop the dilution prior to the loss of SHUTDOWN MARGIN. Therefore, action must be taken to prevent an inadvertent boron dilution event from occurring. This is accomplished by isolating all the unborated water flow paths to the Reactor Coolant System. Isolating these flow paths ensures that an inadvertent dilution of the reactor coolant boron concentration is prevented. Since CORE ALTERATIONS and addition of unborated water can not be made, the core reactivity is stabilized until the audible count rate capability is restored.

The Completion Time of Immediately assures prompt response by operation and requires an operator to initiate actions to isolate an affected flow path immediately. Performance of Required Actions C.1 and C.2 shall not preclude completion of movement of a component to a safe position. Once actions are initiated, they must be continued until all the necessary flow paths are isolated or the circuit is restored to OPERABLE status.

SURVEILLANCE SR 3.9.3.1 REQUIREMENTS SR 3.9.3.1 is the performance of a CHANNEL CHECK of required channels, which is a comparison of the parameter indicated on one channel to a similar parameter on other channels. It is based on the assumption that the two indication channels should be consistent with core conditions. Changes in fuel loading and core geometry can result in significant differences between source range channels, but each channel should be consistent with its local conditions.
