Associated with the load control unit is a rate sensitive power/load unbalance circuit whose purpose is to initiate control valve fast closing action under load rejection conditions that might lead to rapid rotor acceleration and consequent over speed.

I am curious to find out if a power/load unbalance signal occurred, and if the system reacted as expected per the FSAR.

6/24/2004 OPEN 110 Paulk Hypse

1. In the original (initial) plant configuration what were the power sources for Steam Bypass Control for the preferred (non-vital) power to alternate, and was the alternate

power source vital (class) or another non-vital bus?

2. Under the Plant mod, the SBCS was changed from ABTs to static switches, were the power sources for the preferred and the alternate changed as well?

3. Are all three Units SBCS configurations the same, provide dates when the SBCS ABTs/static switches were installed in all three units?

E-mail sent 6/25/20041. The NORMAL power source at NNNDI1 (D12) has always been from NHNM13 (MID) and the EMERGENCY from PHAM31 (M32). At one time there was confusion as to which source was more reliable and the units were aligning the panels differently. Some were units had the ABT aligned to the Emergency source while others were aligned to the Normal. After the "Ring-Tailed cat" event in Unit 1 we decided to replace the switches and to align them to the Normal source since PVNGS had experienced several loss of off-site power events to either S05 or SOB.

2. The sources remained the same but the alignment changed. The Normal source was now the preferred source and the Emergency was the back-up.

This change came out of the ring-tailed cat event in Unit 1.

3. All the NNND11 and D12 switches have been replaced under DMWO 740601.

Can you have someone track down the date of the modification?

(2) are the lub oil lift pumps to be running to enable the starting of the RCP?

more clearly: is the lube oil lift pump an enabling system for the RCP start circuit?

Tim requested clarification of this statement.

After researching Various documents and then talking to John Holmes I was prepared to give my answer to Dave Loveless, however, I was unable to contact him. I left him a voicemail with my name and phone number and that I will contact him on Tuesday(6/29/2004) with the answer to this question.

6/25/2004 OPEN 118 Paulk Hypse They asked why chapter 15 of the UFSAR stated that the SBCS is unavailable after a loss of offsite power. This does not appear to be the case in Unit 3?
