Subject:
License Amendment Application to Revise Technical Specifications 3/4.6.4.4 - Hydrogen Purge System, 3/4.6.5.1 - Shield Building Emergency Ventilation System, and 3/4.7.6.1 - Control Room Emergency Ventilation System Ladies and Gentlemen:
Enclosed is an application for an amendment to the Davis-Besse Nuclear Power Station (DBNPS), Unit 1 Operating License Number NPF-3, Appendix A, Technical Specifications (TS). The proposed changes involve the subject TS regarding the Surveillance Requirements for charcoal filter laboratory testing to revise the testing methodology used to determine operability of the charcoal filters in the engineered safeguards features (ESF) air handling units. Currently, the DBNPS is required to test charcoal in the ESF air handling units per Regulatory Guide 1.52, Revision 2, " Design, Testing, and Maintenance Criteria For Post Accident Engineered-Safety-Feature Atmosphere Cleanup System Air Filtration and l
Adsorption Units of Light-Water-Cooled Nuclear Power Plants," dated March 1978.
l However, the DBNPS has been utilizing an alternative method of testing which, although it provides accurate assurance that these air handling units will perform their design function, it does not literally comply with a strict l
reading of the TS.
The proposed changes incorporate the current testing j
methodology.

The Action statements of TS 3.6.4.4 and TS 3.9.12 (Refueling Operations - Storage Pool Ventilation) have been entered.
Technical Specification 4.0.3 allows 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> for delaying i

Toledo Edison has performed the attached environmental assessment and determined that the proposed amendment, if approved, will have no signifi-cant impact on the environment or irreversible environmental consequences.
Toledo Edison will evaluate ASTM D 3803-1989 " Standard Test Methcds for Radioiodine Testing of Nuclear-Grade Gas-Phase Adsorbents," for incorporation into the DBNPS Technical Specifications.
