1.0 INTRODUCTION

In accordance with 10 CFR 50.90, Exelon Generation Company (EGC), LLC, hereby requests the following amendment to Appendix A, Technical Specifications (TS), of Facility Operating License Nos. NPF-1 1 and NPF-1 8. Specifically, the proposed change will modify TS 5.7, "High Radiation Area," by incorporating the corresponding wording and requirements from NUREG- 1434, "Standard Technical Specifications General Electric Plants, BWRI6," Revision 2, dated June 2001.

2.0 DESCRIPTION

OF PROPOSED AMENDMENT The proposed changes will replace the current LaSalle County Station (LSCS) TS 5.7 with the corresponding wording and requirements from NUREG- 1434, Revision 2. The marked up and retyped TS pages are contained in Attachments 3 and 4.

3.0 BACKGROUND

TS 5.7 describe the LSCS program to control access to areas within the plant that have radiation levels that exceed 100 millirem per hour (mrem/hr). The current TS 5.7.1 and TS 5.7.3 describe the requirements for access into high radiation areas that have radiation levels that exceed 100 mrem/hr but are less than or equal to 1000 mrem/hr.

The current TS 5.7.2, 5.7.3 and 5.7.4 describes the requirements for access into high-high radiation areas that have radiation levels that exceed 1000 mrem/hr. For those areas where locking is not practical, current TS 5.7.2 and TS 5.7.4 both require the area to be barricaded, conspicuously posted, and have an activated flashing light.

4.0 REGULATORY REQUIREMENTS & GUIDANCE 10 CFR 50.36(c)(5), "Administrative controls.", requires that provisions relating to organization and management, procedures, recording keeping, review and audit, and reporting necessary to assure operation of the facility in a safe manner must be included in a licensee's TS.

5.0 TECHNICAL ANALYSIS

5.1 Design Bases The proposed change incorporates corresponding wording and requirements from NUREG- 1434, into the LSCS TS. The LSCS evaluation of the proposed change concluded the following.

Both the proposed and current TS 5.7.1 describe the requirements for access into areas that have radiation levels that exceed 100 mrem/hr but are

ATTACHMENT 2 Evaluation of Proposed Changes Page 3 of 10 less than or equal to 1000 mrem/hr. The proposed and current TS 5.7.1 are considered to have equivalent level access controls as both contain the need to provide a barricade, conspicuously post the area and issue an RWP to control entrance to the area.

Proposed TS 5.7.2 and current TS 5.7.4 describe the requirements for access into areas that have radiation levels that exceed 1000 mrem/hr.

Proposed TS 5.7.2 and current TS 5.7.4 are considered to have equivalent level access controls as both require these areas to be locked. For those areas where locking is not practical, proposed TS 5.7.2 and current TS 5.7.4 both require the area to be barricaded, conspicuously posted, and have an activated flashing light.

The proposed change includes the deletion of the use of computer controlled doors in current TS 5.7.2. This description is being removed as computer controlled doors are no longer utilized at LSCS. Rather, manual locking mechanisms are used on doors providing an equivalent level of control.

Current TS 5.7.4 also discusses "high-high" radiation areas. The term "high-high" radiation area is a legacy term that is being deleted from the proposed TS. This is an administrative change only to remove an outdated term.

Therefore, LSCS has determined that the proposed change provides an equivalent level of protection as that currently provided.

5.2 Risk Information This submittal is not based on risk informed decision making.

6.0 REGULATORY ANALYSIS

TS 5.7 describes the LSCS program to control access to areas within the plant that have radiation levels that exceed 100 mrem/hr. These administrative controls provide provisions relating to the control of radiation exposure to individuals and thus in accordance with 10 CFR 50.36(c)(5) must be included in the TS.

7.0 NO SIGNIFICANT HAZARDS CONSIDERATION EGC has evaluated the proposed change to the TS for LaSalle County Station, Unit 1 and Unit 2, and has determined that the proposed change does not involve a significant hazards consideration and is providing the following information to support a finding of no significant hazards consideration.

ATTACHMENT 2 Evaluation of Proposed Changes Page 4 of 10 Does the change involve a significant increase in the probability or consequences of an accident previously evaluated?

Response: No The proposed change will modify LaSalle County Station (LSCS) Technical Specification (TS) 5.7, "High Radiation Area," by incorporating into the TS the corresponding wording and requirements from NUREG- 1434, "Standard Technical Specifications General Electric Plants, BWRI6," Revision 2, dated June 2001. TS 5.7 establishes the administrative controls on entry into high radiation areas. High radiation area administrative controls are not a precursor to accidents previously evaluated. Thus, the proposed change does not have any affect on the probability of an accident previously evaluated.

The proposed change in administrative controls on entry into a radiation area does not affect the ability of LSCS to successfully respond to previously evaluated accidents and does not affect radiological assumptions used in the evaluations. Thus, the radiological consequences of any accident previously evaluated are not increased.

Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

Does the change create the possibility of a new or different kind of accident from any accident previously evaluated?

Response: No The proposed change does not affect the control parameters governing unit operation or the response of plant equipment to transient conditions. The proposed change does not introduce any new equipment, modes of system operation or failure mechanisms.

Therefore, the proposed change does not create the possibility of a new or different kind of accident from any previously evaluated.

Does the change involve a significant reduction in a margin of safety?

Response: No The proposed change incorporates corresponding wording and requirements from NUREG- 1434, into the LSCS TS. The LSCS evaluation of the proposed change concluded the following.

Both the proposed and current TS 5.7.1 describe the requirements for

ATTACHMENT 2 Evaluation of Proposed Changes Page 5 of 10 access into areas that have radiation levels that exceed 100 mrem/hr but are less than or equal to 1000 mrem/hr. The proposed and current TS 5.7.1 are considered to have equivalent level access controls as both contain the need to provide a barricade, conspicuously post the area and issue an RWP to control entrance to the area.

Proposed TS 5.7.2 and current TS 5.7.4 describe the requirements for access into areas that have radiation levels that exceed 1000 mrem/hr.

Proposed TS 5.7.2 and current TS 5.7.4 are considered to have equivalent level access controls as both require these areas to be locked. For those areas where locking is not practical, proposed TS 5.7.2 and current TS 5.7.4 both require the area to be barricaded, conspicuously posted, and have an activated flashing light.

The proposed change includes the deletion of the use of computer controlled doors in current TS 5.7.2. This description is being removed as computer controlled doors are no longer utilized at LSCS. Rather, manual locking mechanisms are used on doors providing an equivalent level of control.

Current TS 5.7.4 also discusses "high-high" radiation areas. The term "high-high" radiation area is a legacy term that is being deleted from the proposed TS. This is an administrative change only to remove an outdated term.

Therefore, LSCS has determined that the proposed change provides an equivalent level of protection as that currently provided.

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

Based upon the above, EGC concludes that the proposed amendment presents no significant hazards consideration under the standards set forth in 10 CFR50.92(c), and, accordingly, a finding of "no significant hazards consideration" is justified.

8.0 ENVIRONMENTAL CONSIDERATION

A review has determined that the proposed amendment would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, or would change an inspection or surveillance requirement. However, the proposed amendment does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluent that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed amendment.

ATTACHMENT 2 Evaluation of Proposed Changes Page 6 of 10 9.0 PRECEDENT The proposed amendment incorporates into the LSCS a change that is specific to LSCS to incorporate the wording and intent of NUREG-1434, Rev. 2, into TS 5.7, and therefore, this proposed amendment does not rely upon the issuance of amendments to other licensees.
