As a spacecraft on a research mission hurtles at up to 100,000 miles per hour toward the surface of a gas giant like Jupiter, the atmospheric gases surrounding the spacecraft turn to plasma, and spacecraft temperatures increase to more than 10,000 °F.

Swapping conventional electromagnetic radiation for fast neutrons, a team of research engineers at Lancaster University in the United Kingdom, working with the Jozef Stefan Institute of Slovenia, report that they have successfully transmitted digital information wirelessly using nuclear radiation. The researchers’ attempts to transmit words and numbers using standard ASCII code “were 100 percent successful,” according to a November 10 press release from Lancaster University. Their research will be published in an upcoming issue of Nuclear Instruments and Methods in Physics Research and is now available online.

The Canadian Nuclear Safety Commission (CNSC) has amended Ontario Power Generation’s (OPG) operating license for its Darlington nuclear power station near Clarington, Ontario, allowing the company to produce the medical radioisotope molybdenum-99 using Darlington’s Unit 2 CANDU reactor. OPG subsidiary Laurentis Energy Partners, in conjunction with BWXT Medical, is leading the program to produce Mo-99 at Darlington.

X-energy and Centrus Energy announced last week that they have completed the preliminary design of the TRISO-X fuel fabrication facility and have signed a contract for the next phase of work. The planned facility would produce TRISO fuel particles and pack those particles into fuel forms, including the spherical graphite “pebbles” needed to fuel X-energy’s Xe-100 high-temperature gas reactor.
Point Beach nuclear power plant.
The Nuclear Regulatory Commission has issued for public comment a draft environmental impact statement on NextEra Energy’s application for the subsequent license renewal of its Point Beach reactors, located in Two Rivers, Wis. Subsequent license renewal allows a reactor to operate for 20 years beyond the expiration of its original license renewal.
Framatome’s PROtect accident tolerant fuel assembly undergoes final inspection before delivery to Exelon’s Calvert Cliffs-2 in Lusby, Md.
The nuclear industry’s first 100 percent accident tolerant fuel assembly is in operation at Exelon Generation’s Calvert Cliffs plant, the Department of Energy announced yesterday. The advanced fuel will operate in the reactor for the next four to six years and will be routinely inspected to monitor its performance, the DOE said.
Located in Lusby, Md., Calvert Cliffs houses two pressurized water reactors. Unit 1 is rated at 907 Mwe, and Unit 2 at 881 Mwe.
More than 550 employees will join Framatome as part of its acquisition of Rolls-Royce’s I&C business. (Photo: Business Wire)
French nuclear reactor company Framatome has completed its purchase of Rolls-Royce Civil Nuclear Instrumentation and Control. Framatome announced in December 2020 that it had agreed to acquire Rolls-Royce’s I&C business, which has operations in France, the Czech Republic, and China.
According to Framatome, the transaction builds on the company’s engineering expertise, enlarges its industrial footprint, and expands its global I&C systems development and deployment capabilities.

The construction of Unit 3 at the United Arab Emirates’ Barakah nuclear power plant has been completed, the Emirates Nuclear Energy Corporation (ENEC) announced yesterday on the sidelines of COP26, the high-profile climate confab taking place in Scotland this week and next.
According to ENEC’s announcement, Barakah-3 will now undergo operational readiness activities and is on track to start up in 2023.
