A proactive approach to reactor vessel aging management
Unit 2 at the Prairie Island nuclear power plant near Red Wing, Minn., underwent an outage in fall 2023, which included extensive work on the reactor vessel using a novel approach to replace baffle-former bolts and lower radial clevis insert bolts. The work relied on extensive analysis beforehand to determine which bolts to replace such that only the new bolts were structurally credited for performance of their safety function. This proactive approach eliminated the need for costly contingencies associated with inspections.
An ANS Working Group is the writing committee. These groups of about a dozen people each create the text of ANS Standards. They also make decisions about a standard's maintenance and respond to requests for clarification or interpretation. Many working groups take advantage of the two ANS meetings held each year (June and November) and meet at that time. Others conduct much of their work via telephone, e-mail, and fax.
Some working groups now use web pages to communicate. These pages provide a place to share current drafts with committee members and the public and to discuss the standard's status. The web pages may also provide committee rosters, including meeting minutes and announcements, and discuss the standard. Below you will find various links to working group web pages that are in use.
