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.

Damage caused by neutrons in the first wall of fusion reactor is studied in detail for two different structural materials (Type 316 stainless steel and Nimonic PE-16) in the Princeton fusion power plant design. The first-wall neutron spectrum is calculated by the ANISN code, and a dosimetric analysis is performed for both materials. Moreover, a complete study of damage (swelling and creep) during reactor life is done for Type 316 stainless steel. On the basis of a 1% creep strain, the lifetime of a Type 316 stainless steel first wall is calculated to be ∼2 yr, compared with the ∼22-yr lifetime obtained for Nimonic in the Princeton design. In this way, the economic advantage of a superalloy, compared to stainless steel, has been confirmed.
