PG&E to retire Diablo Canyon nuclear plant by 2025, replace with renewables and energy storage

June 21, 2016

PG&E announced a Joint Proposal with labor and leading environmental organizations that would increase investment in energy efficiency, renewables and storage beyond current state mandates while phasing out PG&E’s production of nuclear power in California by 2025 with the retirement of the Diablo Canyon nuclear power plant—California’s last operating nuclear power generation station.

Underpinning the agreement is the recognition that California’s new energy policies will significantly reduce the need for Diablo Canyon’s inflexible baseload electricity output. There are several contributing factors, including the increase of the Renewable Portfolio Standard to 50% by 2030; doubling of energy efficiency goals under SB 350; the challenge of managing overgeneration and intermittency conditions under a resource portfolio increasingly influenced by solar and wind production; the growth rate of distributed energy resources; and the potential increases in the departure of PG&E’s retail load customers to Community Choice Aggregation (CCA).

Opinion: Uranium Prices Set To Double By 2018

June 16, 2016

by James Stafford of

With prices set to double by 2018, we’ve seen the bottom of the uranium market, and the negative sentiment that has followed this resource around despite strong fundamentals, is starting to change.

Billionaire investors sense it, and they’re always the first to anticipate change and take advantage of the rally before it becomes a reality. The turning point is where all the money is made, and there are plenty of indications that the uranium recovery is already underway.

DOE awarding >$82M to support nuclear energy research and development

June 15, 2016

The US Department of Energy (DOE) ia awarding more than $82 million to 93 projects that will help push innovative nuclear technologies toward commercialization and into the market. These awards provide funding for nuclear energy-related research through the Nuclear Energy University Program, Nuclear Science User Facilities, and Nuclear Energy Enabling Technology programs.

In addition to financial support, a number of recipients will receive technical and regulatory assistance through the Gateway for Accelerated Innovation in Nuclear (GAIN) initiative.

Obama Administration announces actions to sustain and advance nuclear energy in US

November 07, 2015

Although overshadowed by the announcement on denial of a Presidential Permit to build the Keystone XL pipeline (earlier post), on Friday, the Obama administration also on Friday announced and highlighted a number of actions to sustain and advance nuclear energy in the US.

In 2014, nuclear power generated about 60% of carbon-free electricity in the United States, and continues to play a major role in efforts to reduce carbon emissions from the power sector. According to the Administration, the continued development of new and advanced nuclear technologies along with support for currently operating nuclear power plants is an important component of the country’s clean energy strategy.

Joint IEA-NEA report details plunge in costs of renewable electricity; nuclear competitive with other baseload power sources

The cost of producing electricity from renewable sources such as wind and solar has been falling for several years. A new report, a joint project by the International Energy Agency and the Nuclear Energy Agency, provides in detail the contrasting costs for different power generation technologies around the world and shows that renewable sources can produce electricity at close to or even below the cost of new fossil fuel-based power stations, depending upon conditions such as resources and appropriate market and regulatory frameworks.

The report, Projected Costs of Generating Electricity: 2015 Edition, also shows that new nuclear power plants generate electricity more cheaply than other established “baseload” sources—mainly coal- and gas-fired power plants—over the full lifetime of facilities when financing costs are relatively low.

MIT team proposes ARC fusion reactor: affordable, robust, compact

August 10, 2015

Advances in magnet technology have enabled researchers at MIT to propose a new design for a practical compact tokamak fusion reactor that might be realized in as little as a decade: the ARC (affordable, robust, compact) reactor. The stronger magnetic field makes it possible to produce the required magnetic confinement of the superhot plasma—the working material of a fusion reaction—but in a much smaller device than those previously envisioned.

The reduction in size, in turn, makes the whole system less expensive and faster to build, and also allows for some ingenious new features in the power plant design. The proposed tokamak (donut-shaped) reactor is designed to have 500 MW fusion power at 3.3 m major radius and is described in a paper in the journal Fusion Engineering and Design.

DOE to award up to $80M to two advanced nuclear reactor projects

August 01, 2015

The US Department of Energy (DOE) issued a funding opportunity announcement (DE-FOA-0001313) to support the research, development, and demonstration of advanced nuclear reactor concepts. The announcement represents an early step in increasing investment in nuclear advanced reactor technologies, the DOE said.

DOE will partner with industry to fund up to two awards of approximately $6.0 million each in FY 2015. The Energy Department will invest up to $3.6 million in each project, with a federally funded research and development center (FFRDC) providing up to an additional $2.4 million. Recipients will be required to invest $1.5 million as part of the cost share. The funding opportunity allows for multiple-year funding for up to two awards with a total of $40 million in DOE cost share per award.
