The postulated LOCA analysis has been perfomed, as ree,uested by j
the AEC Staff in c necting held on August 22, 1973 cnd in subscqvent telephone conversstions, to detemine the applicable limit on maximum average planar linear hcat gueration rate (l'/.PUICR) for the EXXON nuclear fuel using the l
following coaditions:
1.
Cap conductance valuct. applicable are those found in Figure 3-10 of Reference (2).
2.
Densificatior effects, as detailed in Reference (1),
are to be included.
3.
The cniculational techniques used are those employed in the analysis presentsd in Referer.ce (4).
4.
All cther requirements of the Interim Acceptance Criterin are to be met.
This enlculation has been performed. The results indicate that a M'.H HGR of 13.4 W/f t ir reqdyrd to reet the 2300eF pf al: dad trrpercture I f nj t.

, transfer coefficients utilized in the calculaticr.. h'hile it is the technical judgment of both Jersey Central Power 4 Light Company and EXXON that the utilization of these coefficients is valid and appropriately conservative in accordancc with the Interim Acceptance Criteria, an additional reduction,of the MAPLHGR to 10.8 KW/ft is dictated by the additional 1000 margin. The application of a MAPLliGR under the conditions defined above results in a calculated PCT of 22000F for EXXON Type III E fuel.
It is understood by Jersey Central Power 6 Light Company that these particularly conservative restrictions on the operation of the EXXON fuel in the Oyster Creek Nucicar Generating Station are temporary in nature and that-a meeting is to be held to resolve the Staff concerns within the next week.
Very truly yours
