ASLB adds conditions to Seabrook license amendment

September 15, 2020, 7:03AMNuclear News

An ASLB calls for closer scrutiny of concrete degradation at Seabrook.

An Atomic Safety and Licensing Board has rendered its decision on a challenge to a license amendment concerning concrete degradation—known as alkali-silica reaction, or ASR—at the Seabrook nuclear power plant, upholding the amendment but imposing four additional conditions. The board found the new conditions to be necessary to provide adequate protection of public health and safety, according to a September 11 Nuclear Regulatory Commission press release. (The ASLB is the NRC’s independent body charged with conducting adjudicatory hearings and deciding legal challenges to the agency’s licensing and enforcement actions.)

The challenge to NextEra Energy’s license amendment for Seabrook was brought in 2017 by the C-10 Research and Education Foundation, an opponent of license renewal for the New Hampshire facility, which houses one 1,248-MWe four-loop pressurized water reactor.

Special committee holds first hearing on H.B. 6

September 14, 2020, 3:01PMNuclear News

Some two weeks after its creation, the Ohio House Select Committee on Energy Policy and Oversight held its first hearing on September 10 to consider a potential repeal of the Ohio Clean Air Program Act (H.B. 6).

H.B. 6 is the sweeping energy law that includes subsidies for the state’s two nuclear power plants, Davis-Besse and Perry, and that is currently at the center of an alleged $61-million corruption scheme aimed at guaranteeing its passage.

Newly elected Ohio House Speaker Bob Cupp (R., Dist. 4)—who replaced Rep. Larry Householder (R., Dist. 72) as speaker following the latter’s July 21 arrest as the scheme’s alleged ringleader—announced the committee’s creation in late August. Cupp stated that its goal is “repealing House Bill 6 and replacing it with thoughtful legislation Ohioans can have confidence in.”

The committee’s initial hearing, however, focused only on efforts to immediately repeal the measure. Proponents of two repeal bills—one backed by Republicans (H.B. 746) and one by Democrats (H.B. 738)—argued their positions, with some displaying greater rhetorical gifts than others.

Harnessing the promise of radiation: The art of reasonableness

Radiation has benefited mankind in many ways, including its use as an energy source and an indispensable tool in medicine. Since the turn of the 20th century, society has sought ways to harness its potential, while at the same time recognizing that radiological exposures need to be carefully controlled. Out of these efforts, and the work of many dedicated professionals, the principles of justification, optimization, and limitation have emerged as guiding concepts.

Justification means that the use of radiation, from any radiation source, must do more good than harm. The concept of optimization calls for the use of radiation at a level that is as low as reasonably achievable (ALARA). Dose constraints, or limitation, are meant to assist in reaching optimization and protection against harm by setting recommended numerical levels of radiation exposure from a particular source or sources. Together, these three principles form the bedrock of the international radiation protection system that drives decision-­making and supports societal confidence that radiation is being used in a responsible manner.

Dominion Energy has filed an application with the Nuclear Regulatory Commission to renew the North Anna nuclear power plant’s reactor operating licenses for additional 20-year terms, the Richmond, Va.–based utility announced on September 4. The NRC received the application on August 24.

North Anna, located in Mineral, Va., is home to twin 973-MWe three-loop Westinghouse pressurized water reactors. The filing makes the plant the second nuclear facility in the state to seek subsequent license renewal, after Dominion's filing in 2018 of a similar application to renew the licenses of its two Surry units—twin 874-MWe reactors. The NRC is currently reviewing that application.

(Following its April 2020 meeting, the NRC’s Advisory Committee on Reactor Safeguards issued a report recommending approval of the Surry SLR applications [NN, June 2020, p. 15].)

According to Dominion, the North Anna and Surry units produce 31 percent of the electricity for the company’s 2.5 million customers and 95 percent of the carbon-free electricity in Virginia.

With a design that has just emerged from a rigorous safety evaluation by the Nuclear Regulatory Commission, and a customer—Utah Associated Municipal Power Systems (UAMPS)—getting ready to prepare a combined license (COL) application, what is next for Oregon-based NuScale Power and for near-term small modular reactor prospects in the United States? As milestones are reached, many want to know.

NuScale plans to supply twelve 60-MWe modules for a 720-MWe plant—called the Carbon Free Power Project (CFPP) by UAMPS—to be sited at Idaho National Laboratory. A smaller, 50-MWe module version of NuScale’s design recently became the first SMR to receive a final safety evaluation report (FSER) from the Nuclear Regulatory Commission.

“The NRC design approval represents a significant de-risking factor for the CFPP,” said UAMPS spokesperson LaVarr Webb. The project is “making steady progress,” Webb said, adding that “UAMPS General Manager and CEO Doug Hunter has said it is much more important to do the project right than to do it fast.”

More voices come to the defense of Ohio’s H.B. 6 policy

September 8, 2020, 12:06PMNuclear News

Despite high-profile calls to repeal the scandal-tainted Ohio Clean Air Program Act (H.B. 6) and recent legislation crafted toward that end in both the Ohio House and Senate (66 of 99 House members have reportedly co-sponsored Democratic or Republican bills to repeal H.B. 6), the policy behind the measure continues to garner support.

As reported here on August 26, the six commissioners from Ohio’s Lake and Ottawa counties—home to Davis-Besse and Perry, the two nuclear plants saved from early closure by H.B. 6—have made clear their opposition to an immediate repeal of the act.
