Relating item (1) above specifically to changes to the fire protection program under the standard license condition, changes that maintain compliance with the applicable National Fire Protection Association (NFPA) codes and standards that have been endorsed by the NRC, Appendix R to 10 CFR Part 50, Regulatory Guide 1.189, the applicable Branch Technical Positions, applicable NUREGs, other NRC approved or issued documents would be acceptable.
