SUBJECT:

.CALVERT CLIFFS AMENDMENT ON SHUTDOWN MARGIN AND MODERATOR TEMPERATURE COEFFICIENT f

0 ELD has been asked to concur in a license amendment for Calvert Cliffs-2 which would modify the shutdown margin and moderator temperature l coefficient.

The entire " substantive" evaluation of the

' amendment.in;the'SER consists of one sentence which says the amendment is. acceptable.for Unit.2 based.on an analysis previously done for a similar amendment for Unit I which is applicable to Unit 2.

I don't

'.believe this one sentence evaluation is sufficient to support the l

finding'that there is reasonable assurance of adequate protection for l the,public health and safety.

It would seem that if, in fact, the ASLB analysis supporting the changes for, Unit?1 were:so directly' applicable to Unit 2, licensee would have requested the amendment for: Unit 2 at the same time as.it requested the c

Unit I amendment.

The. fact that licensee did not raises a question as to twhether the analysis' is -directly. applicable without modification.

In.

any'cVent,~this is afseparate license amendment for Unit'2 andlthe SER

in support of this amendment should,.on its own, provide the basis'for.

O the required findings-on this particular amendment..'It may.be

. sufficient in' this :SER' to summarize the evaluation that was done for the p.

'U. nit'15 amendment, if, :in. fact, that' evaluation is directly' and.

unequivocally. applicable:to the-Unit 2 amendment, but the current SER,-

'which does nothing more than reference the Unit.1 licensing action, is

not' sufficient-to. support the. required l findings-for this Unit 2 license amendment..
