Monticello Nuclear Generating Plant License Amendment Reauest Dated December 20.1995 Evaluation of Proposed Changes to the Technical Specifications j for Operating License DPR-22 i

i Pursuant to 10 CFR Part 50, Section 50.59 and 50.90, the holders of Operating License DPR-22 hereby propose the following changes:

l Proposed Chance To page 15g of submittal dated November 14,1995 (added text, deleted-text):

l " Perform required visual examinations and leakage rate testing for Type A containment

, integrated leakage rate tests in accordance with 10 CFR 50 Appendix J, Opdon B, as modified by approved exemptions, and Regularoty Guide 1.163 dated September 1995.

Perform and Type B and C tests in accordance with 10 CFR 50 Appendix J, Option A, as i modified by approved exemptions."

Reason for Chanaes i

i As requested by the NRC for clarification of previous submittal.

1 j Safety Evaluation The proposed amendment will not involve a sianificant increase in the probability or consecuences of an accident previously evaluated.

l The proposed amendment adds specific references for Type A and Type B and C tests.

l As such, the proposed amendments are administrative changes since the actual

! requirements for the performance of primary containment integrated leakage rate

testing are not being changed. No safety-related equipment, safety function, or plant

operations will be altered as a result of the proposed amendments. The change does not affect the design, materials, or construction standards of the primary containment nor the test methods, test acceptance criteria, or testing frequencies applicable to primary containment integrated leakage rate testing. Based on the above, this A-1 i  !

} .

amendment will not cause a significant increase in the probability or consequences of an accident previously evaluated for the Monticello plant.

1 The proposed amendment will not create the possibility of a new or different kind of accident from any accident previous!v analyzed.

{

As stated above, no safety-related equipment, safety function, or plant operations will

, be altered as a result of the proposed change. The proposed amendment does not

change the primary containment design or the test methods, test acceptance criteria, or testing frequencies for primary containment integrated leakage rate testing. As such, the proposed license amendment will not create the possibility of a new or different kind of accident from any accident previously analyzed.

The proposed amendment will not involve a sionificant reduction in the marain of safety.

i

' The proposed amendment does not involve any changes to the test methods, j acceptance criteria, or testing frequency for primary containment integrated leakage

rate testing. Thus, the proposed amendments will not affect the ability of the primary

)- containment to perform its intended safety function and no margins of safety, as defined by the plants accident analyses, are impacted. Primary containment integrated leakage rate testing will continue to be performed in accordance with the regulatory j requirements of Appendix J to 10 CFR Part 50. Based on the above reasoning, the j proposed license amendment does not involve a significant reduction in the margin of safety.

l 1

Environmental Assessment l

Northem States Power has evaluated the proposed changes and determined that:

i

1. The change does not involve a significant hazards consideration. I i

i 2 The changes do not involve a significant change in the type or significant increase in I the amounts of any effluent that may be released offsite, or

! 3. The changes do not involve a significant increase in individual or cumulative occupational radiation exposure.

Accordingly, the proposed changes met the eligibility criterion for categorical exclusion set 3

forth in 10 CFR Part 51, Section 51.22(c)(g). Therefore, pursuant to 10 CFR Part 51 Section ,

l 51.22(b), an environmental assessment of the proposed changes is not required.
