12 Scoping of Non safety-Related Systems, Structures, and Components (10 CFR 54.4a(2))
- Utilized site component database, P&IDs, and isometric drawings
- Reviewed safety related cable / piping locations
- Performed walkdowns for a(2) scope verification JAFNPP License Renewal Project JAFNPP License Renewal Project
13 Scoping of Non safety-Related Systems, Structures, and Components (10 CFR 54.4a(2))
- Regional Inspection verified a(2) scoping for in-plant areas and systems
- 10 CFR 54.4a(2) scope changes made in LRA Amendment 11
- Regional Inspection concluded that JAF had implemented an acceptable method of scoping and screening of non-safety related SSCs and that this method resulted in accurate scoping determinations JAFNPP License Renewal Project JAFNPP License Renewal Project
14 Draft SER Summary
- Open Items - 2 Reactor Vessel Fluence Environmentally Assisted Fatigue
- Confirmatory Items - None JAFNPP License Renewal Project JAFNPP License Renewal Project
15 Reactor Vessel Neutron Fluence Current P-T curves valid through 2014 (32EFPY)
Submit RG 1.190 calculations by September 2007 Evaluated TLAAs to determine limiting fluence (RG 1.99)
Adjusted Reference Temperatures (<200F)
Upper Shelf Energy (>50 ft-lb)
RPV welds RPV nozzles near beltline
- ART and USE values will not be challenged at 54 EFPY JAFNPP License Renewal Project JAFNPP License Renewal Project
16 Environmentally Assisted Fatigue
- JAF will demonstrate that cumulative usage factors (CUF) of the most fatigue sensitive locations are less than 1.0 throughout the license renewal period by first using Option (1) of commitment #20
- Analysis methods for determination of stresses and fatigue usage will be in accordance with NRC endorsed ASME Boiler and Pressure Vessel Code
- JAF will utilize design transient specifications and information from BWR-4 references to bound operational transients JAFNPP License Renewal Project JAFNPP License Renewal Project
17 Environmentally Assisted Fatigue Environmental effects on fatigue usage will be assessed consistent with the Generic Aging Lessons Learned Report, NUREG-1801, Rev. 1.
If Option (2) becomes necessary, plant inspection program will be described in terms of the ten elements specified in Branch Technical Position RLSB-1.
If Option (3) becomes necessary, repair or replacement will be in accordance with plant procedures that meet ASME Section XI requirements.
Above actions will be incorporated into the Fatigue Monitoring Program.
The Fatigue Montoring Program will manage the effects of EAF in accordance with 10 CFR 54.21(c)(1)(iii).

James A. FitzPatrick FitzPatrick Torus Repair
32 Torus Repair Torus Repair Torus shell through-wall leak reported in June 2005 Leak was located in same bay as HPCI Steam Discharge pipe near ring girder gusset plate weld ASME Section XI code repair performed in July 2005 by removing the flaw and adding a circular repair plate Root cause of flaw was vibration fatigue from HPCI steam condensation oscillation loading
33
34 Torus Leak 2005 Torus Indication 2006 HPCI Open End Discharge Ring Girder Gusset Plate
35 Torus Repair Torus Repair A HPCI Steam Exhaust Sparger assembly was added during refueling outage October 2006 The sparger directs steam flow away from the Torus shell The sparger significantly reduces loads on the Torus shell from HPCI Steam condensation oscillation
36
37 Torus Repair Torus Repair Extent of condition actions from Root Cause required additional shell exams during refueling outage October 2006 ASME visual exams of similar ring girder gusset welds performed at HPCI and RCIC steam discharge locations General visual exams of similar ring girder gusset welds performed at several locations throughout the Torus Exam results reported shell base metal flaws at two additional locations in the HPCI discharge bay
38
39 Torus Repair Torus Repair ASME Section XI code repairs were performed by grinding to remove the flaws and welding to restore configuration Review was performed to confirm the HPCI steam discharge loading also caused these flaws
