MARVEL PDSA approval could serve as blueprint
MARVEL, the Microreactor Applications Research Validation and Evaluation project at Idaho National Laboratory, has had its preliminary documented safety analysis approved by the Department of Energy, marking a milestone in its development and serving as a potential outline for other microreactors in development.

Integral neutron capture and neutron fission cross sections have been measured for the 276-day 254gEs. Thermal cross sections and resonance integrals were evaluated using a cadmium filter technique. Capture cross sections were determined from alpha-particle spectrum measurements following neutron irradiations with cobalt flux monitors. Fission cross sections were measured using fission track detection techniques with 233U monitors. The fission cross-section values compared favorably with an absorption cross-section determination from a burnout experiment of 253Es-254Es. The integral neutron capture and fission cross sections determined for 254gEs are: = 28.3 ± 2.5 and Ic = 18.2 ± 1.5 b, and = 1970 ± 200 and IF = 1200 ± 250 b.
