Ben Heard of Think Climate Consulting and DecarboniseSA.com joined me for a discussion about the nuclear fuel cycle in Australia. In early February, the South Australian government announced the formation of a royal commission to investigate the state’s future role in the nuclear fuel cycle. As Ben explained, royal commissions are fairly rare and only […]
Nuclear Fuel Cycle
How do metal alloy fuel fast reactors respond to rapid reactivity insertion events?
Update: (Posted Feb 21, 2015 at 7:22) The title has been modified after initial discussion indicated it was incomplete. Other related updates are in blue font. Fast neutron spectrum reactors offer one answer to the trump question that is often used to halt informative discussions about using more atomic energy to reduce our excessive dependence […]
Proving a Negative – Why Modern Used Nuclear Fuel Cannot Be Used to Make a Weapon
Editor’s note: This post was first published on Jul 24, 2010. While working on a new post involving the use of fast spectrum reactors to address many important society challenges, I thought it would be worthwhile to share this important background piece to let you start thinking about some of the misinformation you might have […]
Slowly accelerate fast reactor development
In one corner are people who are certain that breeder reactors that can effectively use the earth’s massive supply of fertile isotopes — thorium and uranium 238 — should be pursued as rapidly as possible with the assistance of prioritized government funding. In the other corner are people who are just as certain that those […]
Antinuclear activists don’t like continued storage rule
Several of the usual suspects — including Dr. Mark Cooper, Dr. Arjun Makhijani, and Diane Curran — have banded together to assert their opinion that the NRC’s recently issued NUREG-2157, Generic Environmental Impact Statement for Continued Storage of Spent Nuclear Fuel, violates the following provision of the Atomic Energy Act of 1954. In connection with […]
What should we do with the waste?
It’s time to declare that the default argument against nuclear energy has been proven invalid. We know how to effectively store and protect used nuclear fuel. We do it routinely. It is not unusually costly or a burden on future generations. They should be free to make their own decisions about how to make the […]
Is it really necessary to have a deep geologic repository for used nuclear fuel?
Though I have often received quizzical, almost uncomprehending looks from my type ‘A’ colleagues on submarines and in my other jobs, I’ve often been guided by a simple principal of decision-making – “If it’s too hard, quit.” Please don’t think that means I’m the type of person who can never get anything done or who […]
Russia continues sustained fast breeder reactor effort
On June 26, 2014, the 60th anniversary of the start of the 5 MWe Obninsk reactor that was the first reactor in the world to routinely supply electricity to a commercial power grid, Russia started up the latest in a series of sodium-cooled fast reactors, the BN-800. This new nuclear plant is an evolutionary refinement […]
Uranium supply concerns associated with EEU
Russia, Belarus and Kazakhstan signed an agreement to form a Eurasian Economic Union (EEU) on May 29. Uranium market watchers should pay close attention and understand the potential implications of the alliance on the stability of the world’s uranium supply, even though the alliance has been dismissed as unimportant by some media pundits. For example, […]
Improvements in spent fuel pool modeling
During a recent discussion thread on Atomic Insights, a frequent commenter cited a 1997 vintage Nuclear Regulatory Commission document as indicating — in his opinion — that there was always a chance that a spent fuel pool could experience an event that might release dangerous amounts of radioactive material. Besides the fact that the report […]
Boxer allows Markey 16 minutes to grill NRC Commissioners
Yesterday, I posted a video clip showing Barbara Boxer berating the five NRC commissioners for 36 minutes during a hearing that lasted a little less than 2 hours. She used her gavel and power over the committee to dominate the session. The only mention she made of time was when she turned to the time […]
NRC Commissioners support staff analysis on spent fuel storage
On Tuesday, May 27, 2014, the Nuclear Regulatory Commission voted to accept its professional staff’s recommendation to leave its current policy regarding spent fuel storage in place. Despite a large amount of public and political pressure, it will not require licensees to expedite the relocation of used nuclear fuel from carefully engineered and seismically qualified […]
