The latest from WNA on fleet performance and fuel

September 8, 2021, 9:30AMNuclear News

Nuclear power plants around the world generated 2,553 TWh of electricity in 2020, a drop of 104 TWh from 2019’s total, according to World Nuclear Performance Report 2021. The report was released last week by the U.K.-based World Nuclear Association.

Nuclear generation declined in Africa, North America, and Western and Central Europe, rose in Asia (but by much less than in recent years), and remained largely unchanged in Eastern Europe, South America, and Russia, the 68-page report states.

Sama Bilbao y León, WNA director general, notes in the report’s preface that although the nearly 4 percent decline “would be an unequivocal disappointment” in any other year, “in 2020, with overall electricity demand falling by around 1 percent and nuclear reactors increasingly being called upon to provide load-following support to the increased share of variable renewable generation, the resilience and flexibility shown by the global nuclear fleet tell a very positive story.”

In the aftermath of a devastating explosion in the port of Beirut, Lebanon, in August 2020, an International Atomic Energy Agency team visited the country at the government’s request and found no evidence of artificial radionuclides and no increase in radiation levels. The powerful blast, which was caused by an explosion of improperly stored ammonium nitrate, killed more than 200 people and leveled numerous buildings while leaving other buildings standing with possible structural damage. The IAEA recently announced that a different team of experts has traveled to Lebanon with a new mission: to assist the nation in the use of non-destructive testing (NDT) to check the structural soundness of buildings that were impacted by the explosion.

This month’s issue of Nuclear News focuses on the role of probabilistic methods in assessing and mitigating the risk of adverse events at nuclear plants and facilities. It’s a timely topic as we move to launch a new generation of nuclear technologies, but it is only half of a larger question that is universal to the human condition: Are the rewards of a particular thing worth its attendant risks?

Nuclear engineers use hard technical terms like “probabilistic risk assessment” and “core damage frequency,” but other industries have much more colorful ways of describing the holistic risk-reward construct in their world. In finance, it’s known simply as “alpha.” A zero alpha investment suggests that its returns are commensurate with the associated risks. Negative alphas get pushed to the curb, and “high alpha” deals get Wall Street hedge fund managers their house in the Hamptons.

The U.S. Department of Energy and Norway’s Ministry of Trade, Industry, and Fisheries have signed a memorandum of understanding to advance a project aimed at eliminating Norway’s high-enriched uranium by downblending it to low-enriched uranium. If the project is successfully completed, Norway will become the 34th country (plus Taiwan) to be considered HEU-free.

In the downblending process, HEU is mixed with depleted or natural uranium to reduce the U-235 concentration to below 20 percent, resulting in LEU, which cannot be used to make an improvised nuclear device (aka “dirty bomb”). According to the DOE’s National Nuclear Security Administration, the challenge with Norway’s HEU has been that much of it is mixed with thorium, making the use of other disposition techniques more problematic.

A closer look: Signed on September 1 by U.S. energy secretary Jennifer Granholm and her Norwegian counterpart, Iselin Nybø, minister of trade and industry, the MOU calls for small-scale downblending activities to begin in 2022 using Norway’s existing infrastructure. It also paves the way for the eventual deployment of the DOE’s Mobile Melt-Consolidate system to complete the work.

BlackStarTech® Innovation Group asked one simple question:

How do we further improve the response times of our FLEX strategies?

That question led to a second question:

Can we add defense in depth to U.S. FLEX response, enhance safety margins, and strategically provide critical power rapidly and reliably in under 30 minutes for up to 30 days?

The response and resultant innovative journey led to the development of a rapidly deployable and portable battery-powered energy delivery system transforming how the nuclear industry can provide critical DC and AC power to the most essential components and control systems. The BlackStarTech methodology utilizes compact and portable power supplies to further enhance essential equipment availability, as well as providing defense in depth to FLEX and B.5.b response. The portable battery power technology provides an alternative means of electrical power delivery solutions, expanding operator flexibility and optimizing station risk reduction strategies.

Inside the ITER Assembly Hall, aided by a 20-meter-tall sector subassembly tool known as SSAT-2, the first of nine 40-degree wedge-shaped subassemblies that will make up the device’s tokamak is taking shape. On August 30, the ITER Organization announced that all the components of the first subassembly were in place on the SSAT-2. After the wings of the subassembly tool slowly close, locking two vertical coils in place around the outside of a vacuum vessel section that is already wrapped in thermal shielding, the completed subassembly will be ready for positioning in the ITER assembly pit in late October.
