Thea Energy releases preconceptual plans for Helios fusion power plant
Fusion technology company Thea Energy announced this week that it has completed the preconceptual design of its fusion power plant, called Helios. According to the company, Helios is “the first stellarator fusion power plant architecture that is realistic to build and operate with hardware that is available today, and that is tolerant to the rigors of manufacturing, construction, long-term operation, and maintenance of a commercial device.”

As part of the effort to finalize the cleanup activities and enter the postdefueling phase, Three Mile Island Unit 2 (TMI-2) has submitted a safety analysis report to the U.S. Nuclear Regulatory Commission. This report includes a review of the regulations of Code of Federal Regulations 10CFR50. This review resulted in the determination that very few of the requirements in 10CFR50 are applicable to TMI-2. Since a facility entering a nonoperating and defueled phase as part of the early decommissioning process (SAFSTOR) is very similar to the situation at TMI-2, new and clear regulatory guidance addressing this phase of the nuclear cycle would be beneficial to the nuclear industry as a whole.
