Inspection accessibility study of the Millstone 1 reactor pressure vessel
Description
This past spring, Westinghouse received a contract from Northeast Utilities to examine the flange ligament areas and the shell welds in the upper portion of the Millstone Unit 1 RPV. This examination was performed with an inspection tool that is placed inside the vessel and is used routinely at Swedish and Finnish BWRs. The examination also used the UDRPS (Ultrasonic Data and Recording System) data acquisition system that was developed under EPRI funding and has since been used in numerous pressurized water reactor (PWR) exams. The objective of RPC105-01 was to use the information gathered before and during the Millstone Unit 1 examination to perform an inspection accessibility study and to prepare a report covering the lessons learned during the examination that would benefit other BWR utilities considering similar inspections
