“…Fetter, et al have developed a modified version of the NRC's intruder scenario to calculate Class C limits for other long-lived radionuclides (Fetter 1988). The specific activity limits in Table 24 are those for Class C waste that is activated metal.…”

“…Analyses done by other researchers have used the same approach of 10 CFR 61 to estimate specific activity limits for other isotopes not specifically listed in 40 CFR 61 (Fetter 1988, Fetter 1990). These prior analyses also corrected some minor errors in the 40 CFR 61 calculations.…”

“…In Part I we described our method of estimating the production of long-lived radionuclides induced in fusion reactor materials [1]. Briefly, the neutron fluxes used were those typical of the first wall of a lithiumcooled blanket with vanadium-alloy structure.…”

“…In Part I, we noted that the potential of fusion to have lower radiological hazards than fission could be crucial to fusion's ultimate success as a commercial energy source [1]. In particular, a qualitative advantage over fission might be achieved if fusion reactors did not produce any high-level radioactive waste.…”

In Part I we calculated 10 CFR 61 "Class-C" specific activity limits for all long-lived radionuclides with atomic number less than 88 (Ra). These calculations were based on the whole-body dose. We also estimated the production of these radionuclides from all naturally occurring elements with atomic numbers less than 84 (Po) in the first wall of a typical fusion reactor, and thereby derived concentration limits for these elements in first-wall materials, if the first wall is to be suitable for Class-C disposal. In Part II we use the "effective dose equivalent" (EDE), which is a much better indication of the risk from radiation exposure than the whole-body dose, to calculate specific activity limits for all long-lived radionuclides up to Cm-248. In addition, we have estimated the production of long-lived actinides and fission products from possible thorium and uranium impurities in first-wall structures. This completes our study of long-lived radionuclides that are produced from all elements that occur in the earth's crust at average concentrations greater than one part per trillion.
