nt to safety, such as the control room. 5. A description should be provided of the measures, as applicable, to protect against pipe whip, blowdown jet and reactive forces, including: a. Pipe restraint design to prevent whip impact; b. Protective provisions for structures, systems, and components required for safety against pipe whip and blowdown jet and reactive forces; c. Separation of redundant features; d. Provisions to separate physically piping and other components of redundant features; and e. A description of the typical pipe whip restraints and a summary of number and location of all restraints in each system. 6. The procedures that will be used to evaluate the structural adequacy of Category I structures and to design new seismic Category I structures should be provided including: a. The method of evaluating stresses, e.g., the working stress method and/or the ultimate strength method that will be used; b. The allowable design stresses and/or strains; and BTP 3-3-11 Revision 3 - March 2007 c. The load factors and the load combinations. 7. The structural design loads, including the pressure and temperature transients, the dead, live and equipment loads and the pipe and equipment static, thermal, and dynamic reactions should be provided. 8. Seismic Category I structural elements such as floors, interior walls, exterior walls, building penetrations and the buildings as a whole should be analyzed for eventual reversal of loads due to the postulated accident. 9. If new openings are to be provided in existing structures, the capabilities of the modified structures to carry the design loads should be demonstrated. 10. Verification that failure of any structure, including non-seismic Category I structures, caused by the accident, will not cause failure of any other structure in a manner to adversely affect: a. Mitigation of the consequences of the accidents; and b. Capability to bring the unit(s) to a cold shutdown condition. 11. Verification that rupture of a pipe
