SOURCES and DNSITE PWER DISTRIBUTION SYSTEMS The OPERABILITY of the A.C. and D.C. power sources and associated distribution systems during operation ensures that sufficient power will be available to supply the safety related equipment required for (1) the safe shutdown of the facility and (2) the mitigation and control of accident conditions within the facility. The minimum specified iC-jent and redundant A.C. and D.C. power sources and distribution systems satisfy the requirements of General Des 19n criteria 17 of Appendix A to 10 CFR Part 50.

i The ACTION requirements specified for the levels of degradation of the power sources provide restriction upon continued facility operation commensurate with the level of degradation. ACTIDH statements have been included in the specification to cover all situati)ns where either-one A.C.

source or a combination of two A.C. sources are inoperable. ACTION statements c, e, and f are intended to be followed to completion once entered and should not be exited until both A.C. sources are restored. The OPERA 8ILITY of the power sources are consistent with the initial candition assumptions of the accident analyses and are based upon maintaining at least Division I or II of the onsite A.C. and D.C. power sources and associated distribution systems OPERABLE during accident conditions ' coincident with an assumed loss of offs <ite power and single failure of one of the two onsite A.C. sources. Division III supplie's the high pressure core spray (HPCS) system only.

The OPERABILITY of the minimum specified A.C. and D.C. power sources and associated distribution systems during shutdown and refueling ensures that (1) the facility can be maintained in the shutdown or refueling condition for extended time periods and (2) sufficient instrumentation and control capability is available for monitoring and maintaining the unit status.

SOURCES and GNSITE PGfER DISTRIBUTION SYSTEMS The OPERABILITY of the A.C. and D.C. power sources and associated i distribution systems during operation ensures that sufficient power will be-available to supply the safety related equipment required for (1) the safe shutdown of the facility and (2) the mitigation and control of accident conditions within the facility. The minimum specified independent and redundant A.C. and D.C. power sources and distribution systems satisfy the requirements of General Design Criteria 17 of Appendix A to 10 CFR Part 50.

I The ACTION requirements specified for the levels of degradation of the power sources provide restriction upon continued facility operation commensurate with the level of degradation. ACTION statements have been included in the specification to cover all situations where either one A.C.

source or a combinatic of two A.C. sources are inoperable. ACTION statements e, e, and f are intended to be followed to cespletten once entered and should not be exited until both A.C. sources are restored. The OPERABILITY of the power sources are consistent with the initial condition assumptions of the accident analyses and are based upon maintaining at least Division I or II of the onsite A.C. and D.C. power sources and associated distribution systems.

OPERABLE during accident conditions coincident with an assumed loss of offsite power' and sing' e failure of one of the two.ensite A.C. sources. Division III supplies the high pressure core spray (HPCS) system only.

The OPERABILITY of the minimum specified A.C. and D.C. power sources and associated distribution systems during shutdoun and refueling ensures that I

(1) the facility can be maintained in the shutdown or refue19ng condition for extended time periods and (2) sufficient instrumentation and control capability SH5ER is available for monitoring and maintaining the unit status.

The ACTION requirements specified for the levels of degradation of 'de with the level of degradation. power sources provide restriction upon continued facilit The OPERABILITY of the power sources are consistent with the initial condition assumptions of the safety analyus and are based upon maintaining at least one redundant set of onsite A.C. anu D.C.

When one diesel generator is inoperable, there is an additional ACTION requirement to verify that all required systems, subsystems, trains, components and devices, that depend on the remaining OPERABLE diesel generator as a source of emergency power, are also OPERABLE, ;

and that the diesel-driven auxiliary feedwater pump is OPERABLE. r ment is intended to provide assurance that a loss-of offsite power event willThis require-not result in 'a complete loss af safety function of critical systems during the period one of the diesel generators is inoperable. The term verify as used in this context means to administrative 1y check by examining logs or other information to determine if certain components are out-of-service for maintenance or other reasons. It does not mean to perform the Surveillance Requirements needed to demonstrate the OPERABILITY of the component.

The OPERABILITY of the minimum specified A.C. and D.C. power sources 'and associated distribution systems during shutdown and refueling ensures that:

(1) the facility can be maintained in the shutdown or refueling condition for extended time periods, and (2) sufficient instrumentation and control capability is available for monitoring and maintaining the unit status.

y ATTACHMENT C EVALUATION OF SIGNIFICANT HAZARDS CONSIDERATION Commonwealth Edison (Comed) proposes to revise Technical Specifications Section 3/4.8, Electrical Power Systems and the associated Bases for LaSalle County, Byron, and Braidwood Stations. The proposed changes revise surveillance and administrative requirements associated with emergency diesel generators (EDGs) in accordance with the guidance of NRC Generic Letter 94-01, " Removal of Accelerated Testing and Special Reporting Requirements for Emergency Diesel Generators,"

Generic Letter 93-05, "Line-Item Technical Specifications Improvements to Reduce Surveillance Requirements for Testing During Power Operation," and Regulatory Guide 1.9, " Selection, Design, Qualification, and Testing of Emergency Diesel Generator Units Used as Class 1E Onsite Electric Power Systems at Nuclear Power Plants." The proposed changes include:

1. Eliminating increased testing requirements for EDGs,

2. Eliminating special reporting requirements for EDGs,

3. Eliminating the semi-annual fast load test and replacing it with a requirement to load EDG semi-annually in accordance with the vendor recommendations for all test purposes other than the refueling outage Loss of Offsite Power (LOOP) tests,

4. De-coupling the 24-hour endurance run and the LOOP /LOCA (LOOP only for LaSalle) sequencing requirements for the hot start test,

5. Removing Regulatory Guide 1.108 references to testing requirements,

6. Eliminating testing requirements when an EDG becomes inoperable due to an inoperable support system, an independently testable component, or preplanned maintenance or testing, or if there is not a potential common mode failure for the remaining diesel generator,

7. Deleting the requirement for inspecting the EDGs in accordance with procedures prepared in conjunction with its manufacturer's recommendations, and

8. Making editorial changes.

Comed has evaluated the proposed Technical Specification Amendment. Based upon the criteria for defining a Significant Hazards Consideration established in 10 CFR 50.92(c), operation of LaSalle County, Byron, and Braidwood Stations in accordance with the proposed amendment will not:

1

1) Involve a significant increase in the probability or consequences of an accident previously evaluated:

The proposed changes do not affect accident initiators or precursors and do not alter the design assumptions affecting the ability of the EDGs to mitigate the consequences of an accident.

Deleting the special reporting requirements from the Technical Specifications is administrative. Comed will continue to notify the Commission of significant EDG failures in accordance with 10 CFR 50.72 and 50.73 criteria.

Excessive testing requirements have proven to be a contributor to increased equipment degradation. Removing inappropriate and redundant requirements increases EDG reliability and enhances the ability of EDGs to mitigate the consequences of an accident. Implementing Comed's alternative to the maintenance rule for the EDGs provides additional assurance that high EDG performance will be maintained.

! EDG equipment degradaticn will be reduced by eliminating the semi-annual fast load test for EDGs in accordance with the vendor recommendations for test purposes other than the refueling outage Loss of Offsite Power (LOOP) tests.

This improves EDG reliability and availability and further enhances their ability to mitigate the consequences of an accident. The LOOP test would still be performed to provide assurance that the EDG is capable of responding to a LOOP as assumed in the accident analyses.

De-coupling the 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months endurance test and the LOOP /LOCA (for LaSalle, LOOP) sequencing test requirements for the hot start test has no effect on accident mitigation. Demonstrating diesel generator hot restart capability without loading the engine does not invalidate or reduce the effectiveness of the hot restart test. The hot restart test can be conducted in any plant condition since its performance at power will have no adverse effect on plant operations.

The proposed editorial changes are administrative in nature. They improve readability and provide consistency with current industry guidance.

Therefore, the proposed changes do not involve an increase in the probability or consequences of an accident previously evaluated.

2) Create the possibility of a new or different kind of accident from any accident previously evaluated:

l The proposed changes do not alter the ability of the EDGs to perform their

! intended function to mitigate the consequences of an initiating event within the acceptance limits assumed in plant safety analyses. The proposed changes have no impact on component or system interactions, or the plant design basis.

2

l Instrumentation setpoints, starting, sequencing, and loading functions associated ,

with EDGs are not affected by the proposed changes. Furthermore, combining i the alternate EDG system maintenance rule implementation program with the l proposed amendment will enhance both the availability and the performance of the EDGs.

Therefore, there is not a potential for creating the possibility of a new or different type of accident from any accident previously evaluated.

3) Involve a significant reduction in a margin of safety:

The proposed changes do not increase the probability or consequences of an accident, and there is no impact on equipment design or operation. The proposed changes do not affect the results of accident and transient analyses.

Plant and system response to an initiating event will remain in compliance within the assumptions of safety analyses. There is no associated change to the type, amount, or control of radioactive effluents, nor is there an associated increase in individual or cumulative occupational radiation exposure. There is no effect upon the capabilities of the associated systems to perform their intended functions within the allowed response times assumed in safety analyses.

l The proposed changes are compatible with plant operating experience and are consistent with the guidance provided in NUREG-1366, Generic Letters 93-05 and 94-01, and Regulatory Guide 1.9. In two instances Comed's proposed l

changes deviate from these guidance documents. However, the changes are l' consistent with the intent of the documents or other NRC guidance documents.

Eliminating excessive testing requirements can improve safety by reducing challenges to plant systems and reducing equipment wear and degradation. {

While the proposed changes affect surveillance intervals; there are no changes j to the methods used to perform the surveillances.

EDG reliability and availability will be improved by the proposed changes. The surveillances will continue to demonstrate the ability of the EDGs to perform their intended function of providing electrical power to the emergency safety systems needed to mitigate design basis transients. No margin of safety is reduced.

i Guidance has been provided in ' Final Procedures and Standards on No Significant Hazards Considerations," Final Rule,51 FR 7744, for the application of standards to license change requests for determination of the existence of significant hazards considerations. This document provides examples of amendments which are and are not considered likely to involve significant hazards considerations. These proposed amendments most closely fit the example of a change which may either result in some increase to the probability or consequences of a previously analyzed accident or may reduce in some way a safety margin, but where the results of the change are clearly 3

j within all acceptance criteria with respect to the system or component specified in the standard review plan.

This proposed amendment does not involve a significant relaxation of the criteria used to establish safety limits, a significant relaxation of the bases for the limiting safety system settings, or a significant relaxation of the bases for the limiting conditions for operations. The proposed change does not reduce the margin of safety as defined in the basis for any Technical Specification.

Therefore, based on the guidance provided in the Federal Register and the criteria established in 10 CFR 50.92(c), Comed has concluded that the proposed change does not constitute a significant hazards consideration.

4

ATTACHMENT D ENVIRONMENTAL ASSESSMENT Commonwealth Edison has evaluated the proposed amendment against the criteria for and identification of licensing and regulatory actions requiring environmental assessment in accordance with 10CFR51.21. It has been determined that the ,

proposed change meets the criteria for a categorical exclusion as provided for under 10CFR51.22(c)(9). This determination is based on the fact that this change is being >

proposed as an amendment to a license issued pursuant to 10CFR50 that changes a surveillance requirement, and the amendment meets the following specific criteria-(i) the amendment involves no significant hazards considerations '

i As demonstrated in Attachment C, this proposed amendment does not involve l any significant hazards considerations. ;

(ii) there is no significant change in the types or significant increase in the j amounts of any effluents that may be released offsite As documented in Attachment A, there will be no change in the types or !

significant increase in the amounts of any effluents released offsite. I i

there is no significant increase in individual or cumulative occupational ;

(iii) radiation exposure i The proposed change will not result in changes in the operation or configuration of the facility. Core design will continue to meet all core design criteria, and i reactor operation will not be impacted. There will be no change in the level of l controls or methodology used for processing of radioactive effluents or handling ;

of solid radioactive waste, nor will the proposal result in any change in the normal l radiation levels within the plant. Therefore there will be no increase in individual ;

or cumulative occupational radiation exposure resulting from this change.
