or forward fitting appeal with the NRC in accordance with the process in Management Directive 8.4. DG-1383, Page 18 GLOSSARY Analytical Evaluation A quantitative process to determine the acceptability of postulated flaws, or flaws that exceed the applicable acceptance standards, including predicted future growth, to determine whether a component is acceptable for continued service without a repair or replacement activity. See ASME Code, Section XI, Division 1. Boiling-Water-Cooled Nuclear Power Reactor A reactor type that used water that is converted to steam in the reactor core to cool the core and turn a turbine generator. Inservice Inspection (ISI) Program The plan and schedule for performing actions for assuring the structural and pressure-retaining integrity of safety-related nuclear power plant components in accordance with the rules of ASME Code, Section XI. MANDE Monitoring and nondestructive examination (MANDE) is a term used by ASME Code, Section XI, Division 2, that includes the activities of monitoring, nondestructive examination (NDE), and use of surveillance specimens, as established by the Monitoring and NDE Expert Panel. MHTGR Modular high-temperature gas-cooled reactor. This reactor type operates with a cooling medium, typically helium. The reactor operates at higher temperatures than current light water reactors. The core is generally supported by graphite, which conducts heat away from the core if the normal cooling medium is lost. NIS-2 Form Form used by the ASME to document repair and replacement activities on ASME Code-designed components. Non-Light Water Reactor Nuclear reactor design that cools the reactor core without ordinary water. Owner’s Activity Report The owner’s activity report, OAR-1, is a form in ASME Code, Section XI, Division 2, to document the results of RIM activities that have taken place during a plant outage, or from online inspections, tests, MANDE, and maintenance, repair, and replacement practices that support the RIM
