Preliminary Evaluation of a Nuclear Scenario Involving Innovative Gas Cooled Reactors by Barbara Vezzoni, Nicola Cerullo, Giuseppe Forasassi, Emil Fridman, Guglielmo Lomonaco, Vincenzo Romanello, Eugene Shwageraus

“…This work focuses on a preliminary (and conservative) evaluation of possible advantages that a symbiotic cycle (EPR-PBMR-GCFR) could entail, with special regard to the reduction of the HLW inventory and the optimization of the exploitation of the fuel resources. The comparison between the symbiotic cycle chosen and the reference one (once-through scenario, i.e., EPR-SNF directly disposed) shows a reduction of the time needed to reach a fixed reference level from ∼170000 years to ∼1550 years (comparable with typical human times and for this reason more acceptable by the public opinion). …”

Physical Pathways for JWST-observed Supermassive Black Holes in the Early Universe by Junehyoung Jeon, Volker Bromm, Boyuan Liu, Steven L. Finkelstein

“…To grow the DCBHs, we implement a gas swallowing model set to match the Eddington accretion rate as long as the nearby gaseous environment, affected by stellar and accretion disk feedback, provides sufficient fuel. We find that to create massive AGN in overmassive systems at high redshifts, massive seeds accreting more efficiently than the fiducial Bondi–Hoyle model are needed. …”
