First astatine-labeled compound shipped in the U.S.
The Department of Energy’s National Isotope Development Center (NIDC) on March 31 announced the successful long-distance shipment in the United States of a biologically active compound labeled with the medical radioisotope astatine-211 (At-211). Because previous shipments have included only the “bare” isotope, the NIDC has described the development as “unleashing medical innovation.”

This paper summarizes an updated process for risk-informed surveillance frequency control program (RI-SFCP) implementation at nuclear power stations based on lessons learned in recent years. Since 2008, the authors of this paper have played significant roles in implementing industry initiative 5b RI-SFCPs for 20 nuclear power units operated by 8 nuclear power utility companies. These programs include selection and prioritization of specific target surveillance test interval extensions; and development, review, and implementation of surveillance test risk informed documented evaluation (STRIDE) packages designed to support extension of conventional surveillance requirement test intervals, in accordance with “Risk-Informed Technical Specifications Initiative 5b, Risk-Informed Method for Control of Surveillance Frequencies, Industry Guideline,” NEI 04-10, Revision 1 [1]. The scope of work associated with STRIDE development includes probabilistic risk assessment (PRA) case studies, deterministic assessment (DA) evaluations, and, where required, instrument drift evaluation (IDE). The STRIDE implementation efforts have also included support of independent decision-making panel (IDP) meetings at the implementing power stations and IDP member training. The purpose of this paper is to provide a presentation of a refined process for STRIDE development with a focus on instrumentation and control systems based on author experience, which includes support for the development of 122 plant STRIDEs. This paper outlines a framework for practical implementation of an RI-SFCP within the context of an integrated risk-informed performance-based regulation application program with emphasis on instrumentation and control systems.
