Securing the advanced reactor fleet
Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

The gamma radiation in the interaction of 14.9-MeV neutrons with a natural lead sample is investigated by the total gamma radiation measurement technique (TGRM). Forty-nine prompt gamma lines and 8 delayed gamma lines, which come from (n,n') and (n,2n) reactions of 206Pb, 207Pb, and 208Pb, are identified, and their differential production cross sections at 55, 90, and 140 deg are determined. Six mixed gamma-ray peaks are separated, and the production data of the prompt and delayed components are given separately. The production cross sections of three isomeric states (1013.7 keV, (13/2)+, 5.5 ms in 205mPb; 2200.2 keV, 7-, 124s in 206mPb; and 1633.3 keV, (13/2)+, 0.81s in 207mPb) are accurately determined. They are in good agreement with some recent experimental and theoretical results. This is the most successful example of applying TGRM in an (n,x) experimental study following after the aluminum study.
