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

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 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
