Text of additional question from today's meeting RAI FPR X-3 Inconsistencies have been identified in Part X, Section 3.3.1 NFPA 15-1973: Water Spray Fixed Systems for Fire Protection, of the as-designed FPR.

Section 3.3.1 states, in part: However, NFPA 15-1975 forms the design basis of the water spray systems.

In the rest of the FPR, NFPA 15-1973 is identified as the code of record, not NFPA 15-1975.

NFPA 15-1975 does not exist.

Section 3.3.1.2 states in part: In accordance with NFPA 15, Section 4-4.1.2, a design density was determined for this unique application based on analysis of the combustibles.

Section 4-4.1.2 does not exist in NFPA 15-1973.

Correct these inconsistencies.

This RAI may involve an update to the FPR to incorporate the response to the RAI.
