First AP1000 Nuclear Units Reach Key Milestones

June 23, 2018
| No Comments
| Industry News

Two Westinghouse AP1000 nuclear power plants being constructed in China have successfully completed significant project milestones.

Sanmen Unit 1—the world’s first AP1000 reactor—achieved initial criticality on June 21. Initial criticality is a nuclear industry term meaning the reactor’s neutron population has remained steady from one generation to the next and the nuclear fission chain reaction is self-sustaining for the first time.

“Today we completed the final major milestone before commercial operation for Westinghouse’s AP1000 nuclear power plant technology,” Westinghouse President and CEO José Emeterio Gutiérrez said in a press release announcing the accomplishment. “We are one step closer to delivering the world’s first AP1000 plant to our customer and the world—with our customers, we will provide our customers in China with safe, reliable and clean energy from Sanmen 1.”

The next significant step is connecting the unit to the electric grid. Assuming work continues on schedule, Sanmen Unit 1 will be the first AP1000 nuclear power plant to commence operation.

Meanwhile, at the Haiyang facility, fuel loading began on Unit 1—another AP1000 reactor.…

[UPDATED] Trump Administration to Force Purchases of Coal, Nuclear Power

A draft memo circulated by the Trump administration before the National Security Council urges federal action to force grid operators to buy power from uneconomic coal and nuclear plants.

Bloomberg on May 31 first pointed to the existence of the 41-page memo, which is dated May 29 and distributed Thursday. The memo outlines plans for a directive by the Department of Energy (DOE) under Section 202(c) of the Federal Power Act (FPA) to “direct the operators to purchase electricity or electric generation capacity from at-risk facilities.”

The draft memo, which is tagged “Privileged & Confidential, Attorney-Client Privilege,” says that regulatory and economic factors have prompted the premature retirement of “fuel-secure” plants—which include nuclear and coal, but also oil-fired and dual-fuel units with adequate storage. “Although the lost megawatts of power often are replaced by new generation from natural gas and renewable energy sources, this transition comes at the expense of fuel security and resilience,” it says.

The memo reasons that because premature retirements of fuel-secure baseload plants reduce resilience to fuel supply disruptions, and because this “crisis” is caused by regulatory and economic actions, federal and state regulatory bodies as well as the private sector must act promptly “to achieve a lasting solution that meets the needs of both national security and the efficient operation of energy markets.”…

Swift (and Angry) Reaction to Trump Move to Save Coal, Nuclear Plants

Reactions from U.S. energy and legal and regulatory groups began pouring in minutes after the White House confirmed on June 1 that President Trump has directed the Department of Energy (DOE) to act immediately to stop the loss of uneconomic coal and nuclear plants. 

White House Press Secretary Sarah Sanders said in a June 1 statement that President Trump believes in “total energy independence and dominance, and that keeping America’s energy grid and infrastructure strong and secure protects our national security, public safety and economy from intentional attacks and natural disasters.”

Because “impending retirements of fuel-secure power facilities are leading to a rapid depletion of a critical part of our nation’s energy mix, and impacting the resilience of our power grid,” the president has directed Energy Secretary Rick Perry to “prepare immediate steps to stop the loss of these resources, and looks forward to his recommendations,” she said.

The White House confirmation comes hours after the leak of a Trump administration draft memo outlining a plan for federal action to prop up coal and nuclear plants that were unable to compete in wholesale power markets and faced retirement.…

How General Atomics Developed Its Revolutionary Nuclear Fuel Solution

| Industry News

The U.S. is pouring funding into developing new fuel technology for advanced nuclear reactors in a bid to help the flagging industry. On April 27, it awarded General Atomics (GA) $ 3.2 million for two projects that the San Diego, California-based company is developing, including an accident tolerant fuel (ATF) solution that the company says is “truly revolutionary.”

The funding, for which GA will provide a cost share, is aimed to advance development and licensing of new reactor fuel that features silicon carbide (SiC) composite fuel cladding containing uranium carbide (UC) fuel pellets. One project, being conducted in collaboration with the Oak Ridge National Laboratory and the University of Tennessee with total funding of $ 2,763,744, will combine advanced computer modeling and simulation with new microcapsule irradiation to establish techniques that “substantially reduce the time and expense required to qualify new fuels,” the company said. The second project, funded at a total of $ 475,819, would back the pre-application license review of SiC-UC fuel by the Nuclear Regulatory Commission, allowing the company to develop an efficient roadmap for formal regulatory qualification.…

Bill Supporting Xcel Energy Nuclear Plants Dies in Minnesota

May 30, 2018
| No Comments
| Industry News

A bill that would have provided more cost-recovery certainty for Xcel Energy’s two Minnesota nuclear plants didn’t get through the state House of Representatives prior to the legislative session ending on May 20, effectively killing the measure.

The bill would have allowed Xcel to submit proposals to the Minnesota Public Utilities Commission (MPUC) designating each of its nuclear plants—the dual-unit Prairie Island station and the single-unit Monticello plant—as carbon-reduction facilities. As part of the process, the company would have included a proposed statement of the total expected costs, including but not limited to capital investments and operation and maintenance costs associated with the facility’s operation.

The MPUC would then have been required to approve or reject the total expected costs within 10 months of the filing date. The solution would have given Xcel the ability to recover a facility’s total costs outside of a general rate case proceeding. Proponents of the legislation suggested that it would have given Xcel more certainty than it currently has concerning cost recovery.…

Report Says More Nuclear Plants in Financial Trouble

A report from Bloomberg New Energy Finance (BNEF) says the financial struggles of U.S. nuclear power plants continue to increase, and it is likely more plants will be faced with early retirement. It’s another acknowledgement of the tough operating environment for nuclear facilities as gas-fired and renewable energy sources continue to grab more power generation market share in an era of lower electricity costs and slowing demand for electricity.

Nicholas Steckler, an analyst with BNEF, on May 15 said 24 of the more than 60 U.S. operating nuclear power plants are either set to close or will not be able to cover their operating costs through 2021. Steckler wrote in his report that those sites have total generation capacity of 32.5 MW, which is nearly a third of the nation’s total nuclear nameplate generation capacity of just above 100 MW, according to the U.S. Energy Information Administration.

A 2016 POWER magazine report detailed the nuclear retirement picture at that time, and several more units have announced plans for premature closures over the past several months.…
