Oak Ridge National Laboratory and Idaho National Laboratory are being considered as potential sites for a test reactor, where fuels and materials could be tested for new types of nuclear power reactors.

It’s not clear where the test reactor would be built at ORNL, if it’s built there.

The fast-neutron reactor, called the Versatile Test Reactor, would be sodium-cooled and small, about 300 megawatts thermal. It would be based on the GE Hitachi PRISM power reactor. That’s a small module design based on the Experimental Breeder Reactor-II, which operated for more than 30 years in Idaho, the U.S. Department of Energy said in a notice published in the Federal Register on Monday. (Fast neutrons are highly energetic neutrons that travel at speeds ranging from tens to thousands of kilometers per second.)

The Versatile Test Reactor would be a pool-type reactor and use metal alloy fuels that could include uranium, plutonium, zirconium and other alloying metals. It would not be a power reactor, and it would not generate electricity. It could generate at least 4×1015 neutrons per square centimeter per second.

Reactor operations could start as early as the end of 2026, DOE said. Fuel for the reactor could be fabricated at Idaho National Laboratory or the Savannah River Site in South Carolina.

The U.S. Nuclear Regulatory Commission is still reviewing a permit application for a site in west Oak Ridge where two or more small modular nuclear reactors could be built.

The application for the early site permit for the Clinch River Nuclear Site was submitted by the Tennessee Valley Authority on May 12, 2016. The application was supplemented by a revision on January 18, 2019, the NRC said in a notice published in the Federal Register on Friday.

The 935-acre Clinch River Nuclear Site is located in the Roane County portion of Oak Ridge along the Clinch River.

A new class of workers at the Y-12 National Security Complex has been added to a federal energy employees compensation program that was established about two decades ago, officials announced Thursday.

The affected employees would have worked at Y-12 between January 1, 1958, and December 31, 1976. They would have been employees of the U.S. Department of Energy, its predecessor agencies, or their contractors and subcontractors. They would have had an aggregate of at least 250 work days. That could have occurred either only through this employment or in combination with work days that meet the parameters established for one or more other classes of employees in what is known as the Special Exposure Cohort.

The notice that the new class of employees has been added to the Special Exposure Cohort was published in the Federal Register by the Centers for Disease Control and Prevention on Thursday. Oak Ridge Today reported in December that the class was being evaluated, based on exposure to radiation from thorium metal parts and plutonium-241 isotopes, and reported in March that the U.S. Department of Health and Human Services had designated the class of employees to be added. The new designation became effective March 28.

The U.S. Department of Health and Human Services has designated a class of Y-12 employees to be added to a federal worker compensation program that involves certain illnesses and work at sites like Y-12 that are affiliated with the U.S. Department of Energy.

The employees who could be added, unless Congress says otherwise, would have worked at Y-12 between January 1, 1958, and December 31, 1976, when the plant was manufacturing nuclear weapons components during the Cold War. They would have had an aggregate total of at least 250 work days. They could have been employees of DOE, its predecessor agencies, or their contractors and subcontractors.

Oak Ridge Today has previously reported that the workers could be added to the compensation program based on exposure to radiation from thorium metal parts and plutonium-241 isotopes.

(For members) NRC finds no significant impact from producing tritium at Watts Bar 2

Watts Bar Nuclear Plant

Watts Bar Nuclear Power Plant

Watts Bar Nuclear Plant

The U.S. Nuclear Regulatory Commission announced on Monday that there would be no significant impact from producing tritium for nuclear weapons in a second unit at the Watts Bar Nuclear Power Plant in Rhea County.

The project involves the Y-12 National Security Complex in Oak Ridge.

The tritium could be produced in Unit 2 at Watts Bar, which is near Spring City about 45 miles southwest of Oak Ridge.

Tritium, which boosts the yields of nuclear weapons, is already being produced in Watts Bar Unit 1. The Tennessee Valley Authority has been producing tritium there since 2003.

A new class of Y-12 employees could be added to a federal worker compensation program based on exposure to radiation from thorium metal parts and plutonium-241 isotopes between 1958 and 1976, health officials said.

The worker compensation program involves certain illnesses and work at sites like Y-12 that are affiliated with the U.S. Department of Energy.

The program is a result of the Energy Employees Occupational Illness Compensation Program Act, which was enacted in October 2000. The act includes what is known as the Special Exposure Cohort. The new class of Y-12 employees could be part of that Special Exposure Cohort.

That designation would allow eligible claimants to be compensated without the complete reconstruction of a radiation dose or a determination of the probable cause. A covered employee would have to have at least one of 22 specified cancers.

The class of employees being evaluated now would have worked at Y-12 between January 1, 1958, through December 31, 1976, when Y-12 was manufacturing nuclear weapons components during the Cold War. The employees would have had an aggregate total of at least 250 work days, according to a notice published in the Federal Register this month. The class could change, however, based upon the evaluation.

A new class of employees at the Y-12 National Security Complex is being evaluated for possible inclusion in a worker compensation program that involves certain illnesses and work at sites affiliated with the U.S. Department of Energy.

The class of employees being evaluated now would have worked at Y-12 between January 1, 1958, through December 31, 1976, and they would have had an aggregate total of at least 250 work days, according to a notice published in the Federal Register on Friday. The class could change, however, based upon the evaluation.

The decision to evaluate the petition for the Y-12 employees was announced by the National Institute for Occupational Safety and Health, which is part of the Centers for Disease Control and Prevention in the U.S. Department of Health and Human Services.

It’s not clear when the petition was filed, who filed it, or how long the evaluation might take. Oak Ridge Today has requested more information from the CDC. [Read more…]

Twenty tons of uranium could be used to produce tritium for nuclear weapons

About 20 metric tons of highly enriched uranium could be “down-blended” to low-enriched uranium and transferred to the Tennessee Valley Authority for use as a fuel to produce tritium for nuclear weapons, according to a public notice published in the Federal Register this week.

The project involves the Y-12 National Security Complex in Oak Ridge and Watts Bar Nuclear Plant near Spring City in Rhea County, among other sites.

The National Nuclear Security Administration and TVA announced in August that they intend to enter into an agreement to “down-blend” highly enriched uranium to low-enriched uranium in order to help produce tritium, a key “boosting” component in nuclear weapons.

The highly enriched uranium used for the “down-blending” will be processed, packaged, and shipped from Y-12, according to the NNSA. Y-12 is an NNSA site, and it is the main storage facility for certain categories of highly enriched uranium. [Read more…]
