Gentlemen:
By letter dated October 26, 1973, we requested you to supply revised i
curves representing the limits for the average planar linear heat. genera-tion rate set forth in the curves labeled "y" in Figures 4-9Al and 4-9A2 of NEDM-10735, Supplements 6, 7, and 8.
The revision would present the results of detailed heatup calculations to exposures higher than 15,000 MWD /T.
These curves would be applicable to Type I and Type II fuel assemblies.
k For Type III E fuel assemblies', you proposed a new curve by letter dated September 7, 1973. We understand that this curve is based on core heatup calculations,up to 10,000 MWD /T.
Please submit a revised curve that includes the results of detailed heatup calculations to an exposure that exceeds the expected maximum planar exposure during this cycle.
In addition, for the Type III E fuel assemblier, revise your heatup cal-culations to include a sink temperature appropriate to the accident envi-ronment and a heavy element contribution in the decay % at curve equivalent I
to 0.31%.
Also, in support of your request to remove the 100'F penalty associated with the effects of a passive rod in the fuel assembly on the spray heat transfer coefficient, please provide the results of your parametric studies that show the sensitivity of the peak clad temperature to changes in the spray heat transfer coefficient at time of passive rod i
quenching and to changes in quenching time.
The above requested infor-mation should b,e submitted for staff review by November 7, 1973.
Sincerely,
/
