Section 6.2 of the Technical Specifications, i Docket No. 50-184.
In response to the telecon request from Mr. Ted Michaels, we respec'..t"j xibmit the following ,
analysis of this change, as prescribed in 10 CFR 50.92(c).
(1) This requested change does not involve a significant change in the probability or consequences of an accident previously evaluated. In the 1984 license renewal for NIST i Test Reactor, (NBSR-9, Addendum 1) aloss-of flow accident (LOFA) was analyzed. The j principal conclusion was that the fuel temperature rise is well below 'he melting point of ,
L the cladding, and that no fuel damage would result. The number and type of heat l exchangers did not enter this analysis, and therefore neither the probability nor .
consequences of such an accident would be increased.
[
(2) This requested change does not incur the possibility of a new or different kind of accident from any accident previously evaluated. In no accident evaluated do the number or type i of heat exchangers enter; the proposed change will not affect this c'onclusion.
(3) The proposed change does not invalve a significant reduction in a margin of safety. The performance specWj.ons for the heat exchangers are unchanged, and they will be sized
^
appropriately for a MW operation.1 .
4 . l s In view of the above analysis, we conclude that the proposed change involves no significant hazards. The only purpose and effect of the proposed change is to allow full consideration of; the best possible heat exchangers, incorporating the best available technology. The basic design - :
cor.siderations are unchanged with respect to performance, material, design pressure and .
temperature, and fabrication code requirements.4 ,
