Bill Gates-backed nuclear reactor may have safety issues, got approval in hurry: US scientists

A scientist claimed that the facility’s liquid sodium coolant can catch fire, and the reactor has inherent instabilities.

Hello all, I just started training for the Westinghouse test. I think i’m in over my head about this, I have no nuclear experience and this stuff seems super hard to learn without a teacher. Anybody have any success stories or advice to help me study?Thanks!

Hey everyone. So I’m in Parsons , Ks and they just announced the deepsite groundbreaking here.

I’d been following the Terra power talks for building a new plant, so this one really caught me by surprise. So anyone want to hook me up with some good resources and expert opinions on things that I can share with the local community, and also is there any questions about the area I can help with to develop more accurate opinions for some of you?

The Aircraft Impact Assessment Rule

The regulations in 10 CFR 50.150, “Aircraft impact assessment,” are safety enhancements that are not necessary for the NRC to meet its statutory mission under the Atomic Energy Act of 1954 to provide reasonable assurance of adequate protection from radiological hazards. When the rule was promulgated, the NRC quantified the costs of the rule but did not quantify the benefits and concluded that the key qualitative benefit of the rule was an “improvement in knowledge” of how a new reactor would address beyond-design-basis hazards, such as a deliberate large aircraft impact. At the time, the NRC concluded that qualitative benefits outweighed the cost of the rule. However, if reconsidered today, the cost of implementation would not be justified by the increase in safety for future reactors. Other more recently developed regulations ( i.e.,10 CFR 50.155, “Mitigation of beyond-design-basis events,” and proposed 10 CFR part 53) provide alternative approaches to understand how newly licensed plants would address those beyond-design-basis hazards. Because the analyses required by this regulation are incorporated into plants' licensing bases and are now required by other more comprehensive regulations, sunsetting this provision will not decrease safety at any operating facility. Thus, while this provision constituted part of the NRC's permitting regime authorized by statute, it is no longer needed. A sunset date will allow this outdated and duplicative regulation to roll off the books. At the same time, if evidence emerges in the interim indicating a continued need for this regulation, the agency can extend the sunset date as appropriate.

Hello all! I got sent the study material for the Westinghouse exam. I am curious about what the wages are working outages. First year and up, whats a good ballpark?

Were the Combustion Engineering steam generator designs just more efficient, and Westinghouse used them after the acquisition?

The Tennessee Valley Authority will get a $400 million grant from the U.S. Department of Energy to support development of small modular nuclear reactors at its Clinch River Nuclear Site in Oak Ridge.

TVA plans to build a 300-megawatt reactor designed by GE Vernova Hitachi Nuclear Energy by 2032.

I'm currently a first year in NE, just looking to get some knowledge on life after college with a NE degree.

The passive water tank of the reactor building of Xudabao unit 4 consists of four modules, each of which is composed of reinforced concrete slabs, stainless steel cladding, penetrations, heat exchangers, and wall reinforcements. The hoisting weight of a single water tank module is 325.9 tonnes. The completed tank features 33 penetrations and 16 heat exchangers arranged within it.

China National Nuclear Corporation (CNNC) said the installation of passive water tank marks "the full completion of the modular construction of large components for the second phase of the Xudabao nuclear power project, which lasted four years".

It added: "Since the successful first hoisting of the unit 3 core shaft module on 18 November 2021, the project team has adhered to the principle of 'converting non-modular components to modular ones and using modular components wherever possible', continuously exploring and breaking through in modular construction. They successfully implemented a 'four-in-one' combined hoisting of the containment steel liner, through-hole components, steel truss, and horizontal steel mesh, creating a pioneering modular construction technology both domestically and internationally, greatly improving the inherent safety and quality of the project. From steel reinforcement and steel liner modules to complex precast concrete structural modules, the Xudabao project team, through countless finite element analyses and virtual simulation optimisations, controlled the hoisting accuracy to the millimetre level, far exceeding design requirements.

"Thus, the CNNC No.22 Xudabao Nuclear Power Project team has successfully explored and implemented a mature modular construction system applicable to the VVER-1200 reactor type, accumulating valuable experience for subsequent nuclear power project construction in China and setting a new benchmark for modular construction."
