A nuclear advocacy group is asking the Federal Energy Regulatory Commission to review the approval by California regulators of the decision by Pacific Gas and Electric in 2016 to prematurely retire its Diablo Canyon plant—the Golden State’s only remaining operating nuclear power facility—in 2025.

On October 26, the nonprofit organization Californians for Green Nuclear Power Inc. (CGNP) filed a 32-page complaint with FERC in the matter, listing as respondents the North American Electric Reliability Corporation (NERC), Western Electricity Coordinating Council (WECC), California Independent System Operator (CAISO), California Public Utilities Commission (CPUC), California State Water Resources Control Board (CSWRCB), and California State Lands Commission (CSLC).

The Versatile Test Reactor’s conceptual design was approved in September, and a draft environmental impact statement could be released within the week. The completion of more project milestones leading to operation in 2026, however, will depend on congressional appropriations. An expert panel described the need for a state-of-the-art test reactor and the value that the VTR could bring to the U.S. nuclear R&D community over its 60-year lifetime during a recent webinar—“Advanced U.S. Nuclear Research and Development: A Briefing and Discussion on the VTR”—hosted by Idaho National Laboratory.

Craig Piercy, ANS executive director/CEO, moderated the webinar, introducing a project update from VTR executive director Kemal Pasamehmetoglu and facilitating a Q&A session with representatives of the Nuclear Regulatory Commission, the Department of Energy, universities, reactor developers, and the Nuclear Innovation Alliance. A recording of the October 29 webinar is available online. INL also has a video and information online on the VTR.

“I think that the VTR represents part of a larger effort to modernize our infrastructure, develop a new set of technologies, and really preserve our global leadership in the field,” said Piercy. Read on to learn more about the promise the VTR holds for the nuclear community.

With work recently completed on the removal of a former uranium enrichment complex at the East Tennessee Technology Park (ETTP), the Department of Energy is shifting focus to other remediation projects around the Oak Ridge National Laboratory. On October 27, the DOE announced that the Oak Ridge Office of Environmental Management (OREM) is set to begin cleanup of the Experimental Gas-Cooled Reactor at the site.

OREM and cleanup subcontractor UCOR are in the planning stages to fully deactivate the reactor for eventual demolition. The reactor is one of 16 inactive research reactors and isotope facilities that OREM is addressing and cleaning up at Oak Ridge. The cleanup effort will happen concurrently with other OREM cleanup projects underway at the Y-12 National Security Complex in Oak Ridge.

The Department of Energy’s Office of Environmental Management (EM) announced on October 27 that it has completed another of its 2020 priorities—completing the remediation activities on and around the Tonopah Test Range and conveying 70 sites into long-term stewardship. Cleanup of the historic site, located within the Nevada Test and Training Range about 160 miles northwest of Las Vegas, was completed in less than half the time initially estimated, according to the DOE.

Oversight of the 70 remediated sites has now been transferred from the Office of Environmental Management to the DOE’s Office of Legacy Management (LM), which provides long-term surveillance and maintenance of remediated and closed DOE sites. Undersecretary for Science Paul Dabbar and other representatives from the DOE and the National Nuclear Security Administration (NNSA) celebrated the transfer of the sites to LM on October 20.

The Palo Verde Nuclear Generating Station, a three-unit pressurized water reactor plant operated by Arizona Public Service Company, has started using an inspection technology relatively new to the nuclear industry. The technology, called smart pigs (an acronym for “piping inline gauges”), has previously been employed by oil and gas companies for inspecting and cleaning underground pipes. After testing and analyzing smart pig products from several companies, Palo Verde’s underground piping consultant, Dan Wittas, selected a smart pig suitable for navigating the tight-radius bends in the plant’s spray pond piping. The spray pond system consists of piping, a pump, and a reservoir where hot water (from the Palo Verde plant) is cooled before reuse by pumping it through spray nozzles into the cooler air. Smart pigs work by using the water’s flow through the piping to move an inspection tool within the pipe itself. The technology replaces the previous method of pipe inspection, in which various relatively small sections of piping were unearthed and directly inspected, and were considered to be representative examples of the overall piping condition. In contrast, the smart pigs obtain corrosion levels for the length of piping traveled through and allow a corrosion baseline to be established.

In New Delhi earlier this week, U.S. Secretary of State Mike Pompeo and Secretary of Defense Mark Esper joined their Indian counterparts, Minister of External Affairs Subrahmanyam Jaishankar and Minister of Defense Rajnath Singh, for the third U.S.-India 2+2 Ministerial Dialogue—a yearly confab focused on strengthening the strategic relationship between the two nations. (In February of this year, the White House elevated that relationship to Comprehensive Global Strategic Partnership status.)

The first 2+2 dialogue took place in New Delhi in September 2018, with a second held in Washington, D.C., in 2019. Washington is scheduled to host the fourth such meeting next year.

The Nuclear Regulatory Commission has approved a request from the Tennessee Valley Authority to increase the generating capacity of Unit 2 at the Watts Bar nuclear power plant by 1.4 percent, according to an October 27 press release from the agency. TVA submitted its application for the power uprate on October 10, 2019, and the NRC issued the required license amendment on October 21.

The power uprate, which TVA intends to implement by mid-December, will increase Unit 2’s generating capacity from approximately 1,223 MWe to 1,240 MWe.

“The NRC staff determined that TVA could safely increase the reactor’s output, primarily through more accurate means of measuring feedwater flow,” the press release stated, adding, “NRC staff also reviewed the TVA evaluations demonstrating that the plant’s design can safely handle the increased power level.”

Rosenergoatom, the electric power division of Russia’s state-owned nuclear power corporation Rosatom, announced on October 23 that Leningrad II-2 has been connected to the grid. The unit is one of two Generation III+ VVER-1200 pressurized water reactors at the Leningrad nuclear plant.

The reactor will replace Leningrad I-2, a 925-MWe RBMK-1000 light-water–cooled graphite-moderated reactor that will permanently cease operation at the end of 2020 after 45 years of service. Fuel loading at Leningrad II-2 began in July, and initial criticality was achieved in August. Following the trial operation, the unit will be shut down for an additional equipment inspection by a state commission before being put into commercial operation early next year, according to Rosenergoatom.
