Nuclear ServicesFramatome ANP Beats theCompetition in Developingthe TechnologyBecause of Framatome ANP’sinvolvement with Oconee and ANOand because the company invested indeveloping both inspection and repairtechnologies, the company had moreexperience than anyone else when thisproblem surfaced.• Framatome ANP has ElectricPower Research Institute/MaterialReliability Program (EPRI/MRP)approved inspection and repairtechniques• The technology is applicableto all PWR RV head nozzles forCombustion Engineering (CE),Westinghouse (W), and Babcock& Wilcox (B&W) plants• The technology addresses all knownfailure modes at once, includingboth nozzle ID and OD defects plussignificantly degraded nozzles withmultiple axial and circumferentialindications• All repairs are fully qualifiedto the ASME code, are covered byFramatome ANP’s 10CFR50Appendix B QA program and havebeen accepted by the NRC.Framatome ANP’s ExperienceSought After by Many PlantsThe Beaver Valley 1 inspection wentso well that Framatome ANP wasasked to perform the same inspectionon Beaver Valley 2. Surry 1 and 2asked Framatome ANP to performtheir inspection, based upon thereported success at other plants as haveboth Three Mile Island (ultrasonicinspection and repair) and CrystalRiver. These will be followed by CalvertCliffs 1 (2002) and 2 (2003).Blade UT sensors detect and size axial and circumferential cracks in sleevedCRDM nozzlesRemote delivery system for blade inspection of CRDM nozzles reduces doseBenefits of Framatome ANP Approach• Balanced approach uses automation to reduce dose and minimizeimpact on outage schedules while remaining cost-effective• Design life maximized by remediating the heat-affected zone inthe repair area• The technology leaves no crevice. Framatome ANP offers replacementreactor vessel heads, if desired and promises on-time delivery.Advanced Nuclear Power N O 3 January 2002 17
