s, hoses, or nozzles purchased for these strategies should be maintained by licensees. An adequate program for equipment requiring maintenance will include: periodic surveillance checks, start and run checks, and pump flow tests. Other tools, adaptors, wrenches, jumpers, etc., that do not require maintenance or testing should, at a minimum, be stored in an accessible location and periodically inventoried to ensure that the equipment is available when needed. The NRC staff recognizes that equipment must be taken out of service for routine maintenance activities for varying periods of time. However, a program which allows equipment needed to implement the strategies required by 10 CFR 50.54(hh)(2) to be out of service for an indefinite period of time is considered to be inconsistent with the requirement to implement strategies intended to maintain or restore core cooling, containment, and SFP cooling capabilities under the circumstances associated with LOLAs of the plant due to explosions or fire. Holders of COLs or operating licenses should ensure that reasonable controls on the availability of equipment needed to implement the strategies required by 10 CFR 50.54(hh)(2) are included in their procedures and guidance required by the rule. 7. It is expected that some strategies require connecting portable equipment, such as fire hoses or electrical devices that may not have been connected or tested in the configuration proposed for the strategy. They might also require connections between onsite and offsite (e.g., fire departments) equipment that have not been verified. At several licensed power reactor sites, NRC inspectors found incompatible fittings that would have prevented or delayed implementation of the strategy. 19.4-21 Revision 0 – May 2013 Staff Position For procedures that involve connecting various pieces of equipment with fittings, adapters, jumpers or other types of connectors, the application should have a commitment for the licensee to confirm by
