As 2021 closes, Nuclear News is taking a look back at some of the feature articles published each month in the magazine. The October issue focused on plant maintenance and outage management with multiple articles looking at efficient ways to deal with plant maintenance. The article below looks at the herculean effort by INL to lead a full overhaul of the Advanced Test Reactor--a task that happens about every 10 years.

Out of the frenzy of nuclear technology and engineering development at the height of the Atomic Age, a few designs stand out above the rest—designs so innovative that they would not be surpassed for years, or even decades. An example of this unsurpassed design brilliance exists in the form of Idaho National Laboratory’s Advanced Test Reactor.

“ATR is really a beautiful machine,” said Sean O’Kelly, associate lab director for the ATR Complex. “The elegant cloverleaf core and control systems were a stroke of genius that solved just about every key problem of test reactor design. The designers’ solutions to those problems give us a testing capacity and flexibility that have yet to be matched.”

As 2021 closes, Nuclear News is taking a look back at some of the feature articles published each month in the magazine. The August issue was the annual Vendor/Contractor profile issue, with an additional focus on programs to help the current fleet compete in local energy markets. The article below looks at the Utilities Service Alliance's Advanced Remote Monitoring and Diagnostics Services program.

It is no secret that the nuclear power industry is enduring an economic crisis. Brought about largely by the impact of technological disruption across the larger energy market, a number of utilities have had no option but to prematurely shut down some nuclear plants because they could no longer compete in the regions they serve. Many others are similarly at risk.

As 2021 closes, Nuclear News is taking a look back at some of the feature articles published each month in the magazine. The May issue reviewed the economics of nuclear power and provided some great articles on nuclear power plant capacity factors, advanced reactor markets, the economic consequences of plant closures, plant closures as an opportunity for industry engagement with local communities, and the article below that looks at why the electricity markets are failing nuclear power plants.

The Biden administration has a goal to decarbonize the U.S. electricity sector by 2035.1 Achieving this goal would require a massive nuclear power build program. The U.S. nuclear power industry’s size and historical success signal that we are in a good position to do this, but at present, the U.S. nuclear fleet is shrinking. Why is this so, and what can be done to turn the trend around?

Nuclear power and cryptocurrency mining: A perfect match?

December 22, 2021, 3:00PMNuclear NewsFlorent Heidet and Milos Atz

Cryptocurrency ecosystems are rapidly growing and are here to stay. Cryptocurrencies are regularly among the 10 largest traded volumes in financial markets, more and more businesses are accepting crypto payments, and crypto “ATMs” are starting to appear at gas stations and grocery stores. However, cryptocurrencies face one major impediment to widespread public acceptance: energy consumption. Opponents of cryptocurrency often cite its energy and pollution footprints as major reasons against adoption. Energy issues have been tied to significant losses in valuation for the major cryptocurrencies, contributing to volatility in that sector. Although crypto valuations have been quick to recover, the energy and pollution challenges remain.

Where’s the plan?

December 17, 2021, 3:27PMNuclear NewsMatthew L. Wald
The electric power transmission grid of the U.S. consists of thousands of miles of lines operated by hundreds of companies.

To do big things, like building the interstate highway system, or going to the moon, government usually has a plan. Electric companies and grid operators, which are responsible for keeping the lights on, always have a plan. But something unusual has happened in the past few months. About four dozen U.S. utilities, plus the federal government and many states, have promised to do something extremely big: to eliminate carbon dioxide emissions, or cut them drastically. But they are not clear on how.
