nes will be considered adequate by the NRC if licensee staff members are able to walk through the strategies successfully using those guidelines. 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. 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 engineering evaluation or a demonstration that (1) hoses can be connected to each other and to pumps, adapters, and fittings, (2) electrical cables, connectors, and jumpers are compatible; and, (3) fire hoses and nozzles can be attached to lifting devices and/or secured in place as needed. 3. Steam Generator Level The reviewer should verify that for applicants utilizing a nuclear power plant design similar to current operating pressurized water reactors (PWRs) that have adopted strategies in Section 3.3.2, 3.3.3, or 3.3.4 of NEI 06-12, Revision 3, or similar strategies, should determine whether or not a portable means of measuring steam generator (SG) level is necessary for the strategy to be successful. If so, portable SG level measurement should be included as part of the strategy. The portable means of measuring SG level should provide information on the degree and rate of SG depressurization or makeup rate. The strategies should be described in the application in a manner consistent with guidance in Appendix D of NEI 06-12, Revision 3 and subsequently implemented in the site procedures by the licensee. 4. Staging of Fire Brigade Equipment The reviewer should verify that appropriate fire brigade equipment (i.e., enough turnout gear, self-contained breathing apparatus, and radios to equip a
