The specific information that we need for each reload since the reactor startup is:

1. Day, month and year of reactor ahutdown and restart.

2. The average Uraniuw-23) enrichneet in the reload.

3. If say fraction of the reload was previously exposed, what fraction i was exposed, and what was the exposure in megewatt deye per natric tonne of uranium (hWD/MTU) and the quantity of uraniun in actric tonnes (IC).

4 The predicted average exposure in WD/?ftU at the tino the fuel was loaded.

5. The eatinated average exposure in MUD /1trU of the discharged fuel.

If lese than 90% of predicted, explain why.

6. The average Uranium-235 enrichnent when discharged.

9. Did the reactor have sufficient reactivity 1 cit to operate at full power when it was shut down for reloading?

.10. Was the reactor shut down for other than raa.ctivity limitationo that were expected to exist prior to the next - 4 '.ing? If yes, why?

(See No. 5)

11. Was an incore power. monitoring progren used to eniculate the discharged exposure? If not, how were the exposures ascertained?
