• Motivation & Background

Location / Date: NRC HQ, TWFN Auditorium, Rockville, MD, October 1-4, 2024 (Tue-Fri)

Format: This is a hybrid (in-person in the TWFN Auditorium) or virtual (via Microsoft Teams) event. In-person attendees are requested to register by July 15, 2024. For online attendees, please check for online connection information on this web page closer to the time of the event.

Objectives:

Explore or assess the state of knowledge (including operating experience, research activities, and associated engineering analyses) related to the performance of passive SSCs during LTO (i.e., > 80 years) and identify any research needs to provide assurance of the adequacy of existing AMPs or identify any needed modifications or additions.

Motivation & Background:

In 2021, NRC completed an activity in ADAMS to assess the feasibility of extending the time period for license renewal of nuclear power plants from the current 20 year maximum to a maximum period of 40 years, and to identify options to implement this change.   One of the three main recommendations of this activity was to consider an evaluation to identify on-going research activities (related to concrete, cables, reactor vessel internals and reactor pressure vessels) that could be extended to greater exposure levels (e.g., higher fluence levels) to address the potential for reactor operations up to 100 years.

Earlier, in 2019, (RIL-2020-12) NRC held an international workshop on age-related degradation of reactor vessels and internals.  While the workshop presenters varied greatly among government, academic, and industry organizations, their experiences with materials aging management were remarkably similar.
