Virginia utility considers SMRs
Dominion Energy Virginia has issued a request for proposals from leading nuclear companies to study the feasibility of putting a small modular reactor at its North Anna nuclear power plant.
While the utility says it is not a commitment to build an SMR at the site, the RFP is “an important first step in evaluating the technology and the North Anna site to support Dominion Energy customers’ future energy needs consistent with the company’s most recent Integrated Resource Plan.”

Previously, a neutronic study of an accelerator-based epithermal neutron irradiation facility (AENIF) for boron neutron capture therapy (BNCT) was performed using three-dimensional Monte Carlo transport calculations. The major components of the AENIF are a radio-frequency quadrupole proton accelerator, a 7Li target, and a moderator assembly. Neutrons are generated by bombarding the 7Li target with 2.5-MeV protons. The neutrons emerging from the 7Li target are too energetic to be used for BNCT and are moderated as they traverse the moderator assembly to the patient. The design of a moderator assembly for an AENIF for the treatment of glioblastoma is reviewed, and this design is compared with the design of a moderator as sembly for an accelerator thermal neutron irradiation facility (A TNIF) for the treatment of superficial melanoma. The ATNIF moderator assembly consists of a 50-cm-high × 30-cm-diam cylinder of D2O, surrounded on its top and sides by a 40-cm-thick graphite reflector. This moderator assembly creates, at the surface of a large phantom at its irradiation port, a boron absorbed dose rate of (3.2 ± 0.2) cGy/(min · mA), for a tumor 10B concentration of 24 µg of10B per gram of tissue. For a single-session dose equivalent of 40 Sv to the tumor, the treatment time is 13 min for a 30-mA proton beam. With different moderator assemblies, a 30-mA, 2.5-MeV proton accelerator can be used to treat both superficial and deep lesions from melanomas and gliomas.
