SC Nuclear Summit focuses on V.C. Summer
The second annual South Carolina Nuclear Summit held last week featured utility executives and legislators from the state, as well as leaders from Brookfield Asset Management, which is being considered to restart construction on the two abandoned reactors at the V.C. Summer nuclear power plant in Fairfield County. The summit, at the University of South Carolina’s Colonial Life Arena, attracted more than 350 attendees. The event was hosted by the university’s Molinaroli College of Engineering and Computing.

Prompt-neutron decay constants have been determined for unreflected and unmoderated subcritical cylinders of enriched uranium (93.15 wt% 235U) by the Rossi-α technique. The cylinder diameters were 17.77, 27.93, and 38.09 cm and the heights varied from 10.184 to 2.548, 8.431 to 5.399, and 7.502 to 4.780 cm, respectively. The decay constants agreed to within 4% with those measured by the pulsed-neutron method; the comparison with the results of Sn transport theory calculations showed disagreements as large as 20%. The ratio of the prompt-neutron decay constant of a cylinder at delayed criticality to that of a subcritical cylinder and the ratio of the corresponding prompt-neutron lifetimes were used to obtain subcritical reactivities as great as 33 dollars. The lifetimes were calculated using neutron fluxes from S8 transport theory. These reactivities agreed favorably with values determined by an analog computer whose input was the response of an ionization chamber to power changes when an assembly was disassembled from delayed criticality to a given reactivity.
