The newest era of workforce development at ANS
As most attendees of this year’s ANS Annual Conference left breakfast in the Grand Ballroom of the Chicago Downtown Marriott to sit in on presentations covering everything from career pathways in fusion to recently digitized archival nuclear films, 40 of them made their way to the hotel’s fifth floor to take part in the second offering of Nuclear 101, a newly designed certification course that seeks to give professionals who are in or adjacent to the industry an in-depth understanding of the essentials of nuclear energy and engineering from some of the field’s leading experts.

Monoenergetic gamma beams (Δ ~ 10 eV) based on thermal neutron capture, in a nuclear reactor, using the V(n,γ) and Fe(n,γ) reactions were utilized for generating fast neutron sources from lead and thallium, respectively, via the 207Pb(γ,n) and 205Tl(γ,n) reactions. It so happens that one of the incident gamma lines of the V source, Eγ = 7163 keV, photoexcites by chance a resonance level in 207Pb, which emits neutrons at an energy of 423 keV. In a similar manner the incident gamma line at Eγ = 7646 keV of the Fe(n,γ) source photoexcites by chance a resonance level in the 205Tl isotope, which emits neutrons at an energy of 99 keV. The cross sections for the neutron emission process were measured and found to be σ(γ,n) = 35 ± 6 mb and 107 ± 17 mb, respectively, with intensities of the order of 104 n/s.
