Subject:
', Byron-and Braidwood Stations Units 1 and 2 Technical Specification 3.8.2.1 NRC Docket'Nos. 50-454/455'and 50-456/457
Dear'Dr. Hurley:
Byron and Braidwood Stations submitted applications for
- amendments to Technical. Specification 3.8.2.1 and received approval of Amendments 5 to enable the use of.the D.C. crosstie breakers between opposite unit D.C. buses. Members of your Staff recently questioned the
-administrative functionality of the Amendment for that use.
Commonwealth Edison' believes'that the Amendment as stated in the Technical 1
-Specifications: technically permits the use of the D.C. crosstie
-breakers.
The administrative concern:is created due to an action
'. statement that affects both units.
Commonwealth Edison attempted to
-satisfy:the_-administrative needs of the specif_ication when the amendment
-was submitted and we believe the present specification accomplished that
- goal.
However, due to the recent concern, we have asked for assistance from the Staff with the development of an acceptable crosstie Specification.
To date the Staff has not recommended an alternative.
,Therefore, with the Byron Station Unit I refueling outage rapidly approaching in January, 1990, Commonwealth Edison will utilize Technical Specification 3.8.2.1 as vritten and approved in Amendment 5 at Byron and Braidwood= Stations permitting the use of the D.C. crosstle breakers.
In the future, if the Staff concludes ~that an alternative exists that satisfies the edministrative concern,-then Commonwealth Edison will review'the alternative and consider the submittal of an amendment.
Please direct any questions regarding this matter to this office.
Very truly yours, h0 0"d2d R. A.
