Branch 3 Status 4/29/10 Attachments: B3-Status 4-29-10doc See attached The following are the remaining open AFW inspection questions as of a few days-ago

• Verify hydro/pressure test is code compliant - O'Hara, determined approach was acceptable, received test records but still needs to verify test results. PSEG will also provide the leak check procedure by 4/27 am.

Smart samples o Verify repairs to the control air system elbow that was replaced (how will PSEG certify the repair) -

O'Hara, PSEG adding more detail to description of document, to provide by 4/27 PM o Verify control air extent of condition - O'Hara o Backfill procedure reviews to verify coating and backfill cure times - O'Hara, PSEG to provide by 4/27 pm o Verify control air clamping material - O'Hara, PSEG to provide supporting document 4127 am o AFW pipe weld records - O'Hara, PSEG to assess status'of documents by 4/27 pm

• Verify hydro/pressure test is code compliant - O'Hara, determined approach was acceptable, received test records but still needs to verify test results. PSEG will also provide'the leak check procedure 4127 am.

• Evaluate the 50.59 for AFW modifications - Scroeder reviewed no significant technical concerns or Issues

• Design records for as installed AFW piping on Unit 1 &2 not found Outside of Scope

Outside of Scope U*nit 2 AFW Testinq - PSEG determined that they did not perform ASME code required pressure drop test for the buried sections of the S22 and 24 headers.

9 Confirm the PSEG risk assessment to delay AFW testing for 1 year is reasonable - Cahill, complete, no concerns

• Evaluate if performing a risk assessment to meet Technical Specification 4.0.5 is appropriate if a test was never performed verses missed - Conte/Ennis - discussions ongoing, no apparent ongoing compliance issues.

Operability, Initial assessment Unit 2 was that it is in better condition based on newer piping; 1994 inspection that identified intact coating; and ISI code gives more allowance to an operating unit (can take credit for up to 90% of the yield Stress).

• Evaluate the Unit 2 AFW extent of condition operability assessment - Schroeder no significant technical issues or A concerns 4 Confirm the finite element analysis for the Unit 1 as found condition is acceptable including the use of appropriate methods and assumptions - Gray, O'Hara, and HQ reviewed, no significant technical issues or concerns Outside of Scope
