This publication is incorporated by reference into both NRC and FEMA regulations. NRC at 10 CFR Part 50 and FEMA at 44 CFR Part 350!
I believe I have referred to the so-called Rasmussen Report several times on this blog. I erroneously listed it as WASH 1100 but in fact the NRC document is WASH 1400!
Sorry for any confusion. And sorry for my slipping memory.
