Alloy 617 is new option for high-temp reactors

May 7, 2020, 9:40AMNuclear News

When it comes to advanced, high-temperature reactors—using working fluids such as molten salt, high-temperature gases, or sodium—there simply are not many qualified materials for nuclear component construction. Alloy 617 is not a new material, but it made the news after Idaho National Laboratory announced that it was recently added to the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel (BPV) Code for high-temperature nuclear applications, bringing the total number of qualified high-temperature materials to six.

INL seeks input on construction technologies

April 27, 2020, 11:54AMNuclear News

Battelle Energy Alliance, the managing and operating contractor for Idaho National Laboratory, is seeking an expression of interest (EOI) from industry stakeholders interested in forming a partnership to develop and/or demonstrate advanced construction technologies and processes. The effort would be executed as an initiative of the National Reactor Innovation Center (NRIC) at INL. Battelle announced the EOI on April 17, with a deadline for responses of May 16.

ANS Young Members Group Chair Harsh Desai

The ANS Young Members Group has developed a new live webinar series that is free to all, and Harsh Desai is excited. “We have a great opportunity to highlight our national laboratory infrastructure, which is a pinnacle of innovation in nuclear science, technology, and engineering,” said Desai, chair of the YMG. “We’re giving each of the national labs the opportunity to highlight their mission, key projects, and rising stars, and we’re also giving members of the YMG executive committee valuable leadership experience building and moderating the webinar panels.”

Experimental Breeder Reactor I: A retrospective

In the not-so-distant 20th century past, our planet was in an uncertain new-world order. The second of two major wars had dramatically reshaped the landscape of the world's nations. It was not by any means assured that the extraordinary nuclear process of fission, which itself had been discovered mere years before the second war's end, would be successfully utilized for anything but the tremendous and frightening powers realized in thermonuclear warheads. In the years following, a humble project materializing out of the National Reactor Testing Station in Idaho was to challenge that assertion and demonstrate that nuclear fission could indeed be a commercial, peaceful source of electrical power for civilizations around the globe.

Looking high and low for HALEU

Advanced reactor cores are being designed for higher efficiencies and longer lifetimes, but to get there, they need high-assay low-enriched uranium (HALEU).

Enriched to between 5 and 19.75 percent fissile U-235, HALEU is packed with nuclear potential. It can be used as a feedstock for the demonstration of new fuel designs, from uranium alloys to ceramic pellets and liquid fuels. Those fuels can enable advanced reactor and microreactor demonstrations. Operating light-water reactors could potentially transition to HALEU uranium oxide fuels for extended operating cycles and improved plant economics.

Are the Tides Turning for Advanced U.S. Nuclear?

RadioNuclear.orgWelcome to the New Year!  Even though I am on the road, there is just so much happening lately in nuclear I could not pass up the opportunity to talk about it! This episode of RadioNuclear, we take a look at recent and exciting legislation and policy for advanced nuclear. This includes the passages of the NEIMA and NEICA bills and what the Idaho National Laboratory may look like in the coming years. We also discuss the NRC's recent decision on post Fukushima regulation. Lastly, we look on how you can adopt a dog from the Chernobyl exclusion zone. No, I am not making that up!

EBR-1 in Photos

December 20, 1951 marks an important date in the history of nuclear power; it's the date on which the first useful electric power was generated by atomic fission.  While the now-famous event at that time only powered four light bulbs, the somewhat stunt-like nature of the day obscured the fact that the plant was actually set up to generate considerably more power, and did so.  Let's take a look at this fact and, at the same time, the facility through illustrations from my collection and from photographs that I took myself while touring EBR-1 earlier this year.
