The facility will operate'in conformity with the application, the provisions of.the Act, and the regulations of the Comission; C.

There is reasonable assurance: (1)thatthe'activitiesauthorizedby=

this amendment can be conducted without endangering the health and safety of the public.and (ii) that such activities will be conducted s

in compliance with the Comission's regulations set forth in 10 CFR i

Chapter I; j

D.

The issuance of this amendment will not be inimical to the common defense and security or to the health and safety of the public; and l

E.

The issuance of this amendment lis in accordance with 10 CFR Part 51 l-of the Commission's regulations and_all applicable requirements have been satisfiet 2.

Accordingly, the license is amended by changes to the Technical Specifica-tions as indicated in the enclosure to this license amendment and paragraph
