Content:
the radiation monitors, nuclear instrumentation, manual initiation, and other devices and verify that they are operable to actuate the building evacuation alarm and ventilation control. 3. Specify the status of all systems required for fuel loading. 4. Conduct inspections of fuel, control rods, and poison curtains. 5. Ensure that nuclear instruments are calibrated, operable, and properly located (source fuel detector geometry). One operating channel should have audible indication or annunciation in the control room. 6. Require a response check of nuclear instruments to a neutron source within “N” hours prior to loading (or resumption of loading, if delayed for “N” hours or more), where “N” is consistent with the technical specification surveillance frequency for source range nuclear instruments in the refueling mode (typically 8 or 12 hours). 7. Specify and establish the status of containment. 8. Specify the status of the reactor vessel. Components should be either in place or out of the vessel, as specified, to make it ready to receive fuel. 9. Establish the vessel water level and prescribe the minimum level for fuel loading and unloading. 10. Specify and establish coolant circulation for borated reactors and take precautions (such as valve and pump lockouts) to prevent deboration. 11. Ensure that the emergency boron addition system (or other negative reactivity insertion system) is operable. 12. Check the fuel handling equipment and perform dry runs. 13. Prescribe and verify the status of protection systems, interlocks, mode switch, alarms, and radiation protection equipment. For reactors that have operable control rods during fuel loading, the high flux trip points should be set for a relatively low power level (normally not greater than 1 percent of full power). 14. Establish water quality and identify limits. Appendix C to DG-1259, Page C-6 15. Establish and verify the minimum fuel loading boron concentration. b. Procedure Details The procedure
