W25  Update Process for Approved Transient and Accident Analysis Methods

The NRC staff is considering an update process by which vendors and licensees could update key models in their approved evaluation models.  If such a process were developed, vendors and licensees who adopted the process would be responsible for evaluating key models at certain intervals, but may also have the freedom to update those models without prior NRC review, provided certain conditions were satisfied.  The NRC staff believes such a process would not only enhance safety, but could also reduce regulatory burden.
