We had a "to do" for allegations process to observe CRD performance during restart. If I remember correctly, I think it was reasonably good. We need to document a few words to that effect, or if it wasn't good we need to say that. Could one of you do that by COB tomorrow?

I Scotf Barber - CRDPerfHC.wpd Page 1 1 Objective:

NRC inspectors observation of CRD performance during startup from maintenance outage (March 19 - April 14).

Results:

During the Hope Creek startup (April 8-14, 2004) PSEG experienced a total of 12 stuck control rods. Five of the 12 stuck underwent scram time testing prior to their initial movement. Control rods (26-23, 30-31, 22-15, 38-11,26-39, 30-19, and 26-35) were scram time tested on April 14.

Operators entered abnormal procedure HC.OP-AB.IC-0001 each time they experienced a stuck control rod. The chart below summarizes the control rod performance and what actions they performed.

Control Rod Condition Actions Taken 45-15 Stuck not @ 00 Step 1.2- .2 Operated drive in both directions 22-11 Stuck @ 00 Step F.1 -.4 Operated drive in both directions, vent, and double clutch.

22-35 -Stuck @ 00 -Step F.1 -.4 Operated drive in both directions, vent, and

-Stuck not @ 00 double clutch.

-Step 1.1-1.2 Operated drive in both directions 38-27 Stuck not @ 00 Step 1.1-.4 Operated drive in both directions; raised d/p to 292 psid 26-51 Stuck @ 00 Step F.1-.4 Operated drive in both directions, vent, and double clutch.

50-27 Stuck not @ 00 Step 1.1-.4 Operated drive in both directions; raised d/p to 293 psid 38-11 Stuck @ 00 Unstuck @ normal pressure 26-39 Stuck @ 00 Step 1.1-.4 Operated drive in both directions; raised d/p to 444 psid 30-19 Stuck @ 00 Unstuck @ normal pressure 26-23 Stuck @00 Step 1.1-.4 Operated drive in both directions; raised d/p to 480 psid 26-35 Stuck @00 Step 1.1-.4 Operated drive in both directions; raised d/p to 300 psid(Rod double notching)

Summary:

Hope Creek had 6 control rods stick on startup and in two cases elevated pressures was used to free the rod (38-27 and 50-27). Hope Creek had 5 additional rods (38-27, 50-27, 26-39, 26-23, and 26-35) stick at position 00 following scram time testing. This result is somewhat expected, and why operators usually will perform control rod exercising during a outage Talking w/ operators they were satisfied w/ control rod performance corning out or the forced outage and believe that it was improved over past startups.
