The proposed amendment would delete from the technical specifications (T.S.) of the operating license, the phrase, "in accordance with manufacturer~s-instruction" from the requirement to annually check smoke =

detector sensitivity. This is not possible in all cases due to the fact that some smoke detector models are no longer in production and there is an unavailability of vendor supplied test equipment.

The proposed T.S. amendment will not eliminate or modify any protective funotions nor permit any new operational conditions since an inappropriate restriction on the surveillance requirement.

it only deletes Zt does not create the possibility of a new kind of accident or significantly increase the probability or consequences of an accident previously evaluated since no equipment modifications, instruction changes or operational changes are made.
