SUMMARY

OF OPERATING EXPERIENCE UNIT THREE APRIL, 1984 04-01 to 04-30 Unit 3 remained off-line the entire period with the reactor critical (to maintain temperature). On May 9th, the reactor was shutdown with temperature being main-tained by use of the two recirculating water pumps.

Work on the i?.P. Turbine rotor continues. A portable oven has been erected which is being used to stress relieve and straighten the rotor. Other work includes repair of the stationary seals between stages.

The status of the unit remains "In Refuel".
