r than 50 when measured in accordance with ASTM E-84, "Standard Test Method for Surface Burning Characteristics of Building Materials." Open Circuit — A failure condition that results when a circuit (either a cable or individual conductor within a cable) loses electrical continuity. Revision 4 - October 2003 41 Pre-Fire Plans — Documentation that describes the facility layout, access, contents, construction, hazards, hazardous materials, types and locations of fire protection systems, and other information important to the formulation and planning of emergency fire response. Raceway — A channel of metal or nonmetallic materials designed expressly for holding wires, cables, or busbars, with additional functions as permitted by code. Raceways include, but are not limited to: cable trays, junction boxes, conduit, tubing, raceways, wireways, and busways. Raceway Fire Barrier — Non-load-bearing partition type envelope system installed around electrical components and cabling that are rated by test laboratories in hours of fire resistance and are used to maintain safe shutdown functions free of fire damage. Radiant Energy (Heat) Shield — A noncombustible or fire resistive barrier installed to provide separation protection of redundant cables, equipment, and associated non-safety circuits within containment. Remote Shutdown — The capability, including necessary instrumentation and controls, to safely shut down the reactor and maintain shutdown conditions from outside the main control room. (See GDC 19.) Restricted Area — Any area to which access is controlled by the licensee for purposes of protecting individuals from exposure to radiation and radioactive materials. Safe Shutdown — For fire events, those plant conditions specified in the plant Technical Specifications as Hot Standby or Hot Shutdown, and Cold Shutdown. Safe Shutdown Analysis — A process or method of identifying and evaluating the capability of structures, systems, and components necessary
