Thorium nuclear reactors: no safer than conventional uranium reactors

Dispelling Claim 4: Thorium reactors are safer than  conventional uranium reactors  Thorium ‒ a better fuel for nuclear technology? Nuclear Monitor,   by Dr. Rainer Moormann  1 March 2018

The fission of U-233 results in roughly the same amounts

of the safety-relevant nuclides iodine-131, caesium-137

and strontium-90 as that of U-235. Also, the decay heat is

virtually the same. The differences in produced actinides (see

next claim) are of secondary importance for the risk during

operation or in an accident. In this perspective, thorium use

does not deliver any recognisable safety advantages.

Of greater safety relevance is the fact that uranium-233

fission produces 60% less so-called delayed neutrons than

U-235 fission. Delayed neutrons are not directly created

during the fission of uranium, but from some short-lived

decay products. Only due to the existence of delayed

neutrons, a nuclear reactor can be controlled, and the

bigger their share (for instance 0.6% with U-235), the

larger is the criticality range in which controllability is given

(this is called delayed criticality). Above this controllable

area (prompt criticality) a nuclear power excursion can

happen, like during the Chernobyl accident. The fact that

the delayed super-critical range is with U-233 considerably

smaller than with U-235, is from a safety point of view an

important technical disadvantage of thorium use.

During the design of thermal molten salt reactors (breeders),

the conclusion was that the use of thorium brings problems

with criticality safety that do not appear with classical

uranium use in this type of reactors. For that reason, it was

necessary to turn the attention to fast reactors for the use

of thorium in molten salt reactors. Although this conclusion

cannot be generalised, it shows that the use of thorium can

lead to increased safety problems.

As mentioned, a serious safety problem is the necessity to

restart breeder and reprocessing technology with thorium.

Thorium is often advertised in relation to the development

of so-called advanced reactors (Generation IV). The

safety advantages attributed to thorium in this context are

mostly, however, not germane to thorium (the fuel) but

rather due to the reactor concept. Whether or not these

advanced reactor concepts bring overall increased safety

falls outside the scope of this article, but that is certainly

not a question with a clear “yes” as the answer.

Thorium reactors – NOT a solution to nuclear waste problem

Dispelling Claim 5: Thorium decreases the waste problem  

Thorium ‒ a better fuel for nuclear technology? Nuclear Monitor,   by Dr. Rainer Moormann  1 March 2018

Thorium use delivers virtually the same fission products

as classical uranium use. That is also true for those

isotopes that are important in issues around long-term

disposal.  Those mobile long-lived fission products

(I-129, Tc-99, etc.) determine the risk of a deep geological

disposal when water intrusion is the main triggering event

for accidents. Thorium therefore does not deliver an

improvement for final disposal.

Proponents of thorium argue that thorium use does not

produce minor actinides (MA)5, nor plutonium. They argue

that these nuclides are highly toxic (which is correct) and

they compare only the pure toxicity by intake into the body

for thorium and uranium use, without taking into account

that these actinides are hardly mobile in final disposal

even in accidents.

Toshiba gets out of a uranium deal

Toshiba gets out of GoviEx deal, Mining Journal , 4 Mar 18, 

Japanese conglomerate Toshiba has severed an offtake and bond agreement with uranium producer GoviEx Uranium (CN:GXU) following the sale of its Westinghouse nuclear division to Brookfield.

Toshiba and the Africa-focused uranium explorer signed a US$40 million deal in 2012 in which the Japanese company lent the equivalent of 200,000 pounds of U3O8 (with the bond now worth 382,193Ib because of the compounded interest), as well as an offtake and shareholding agreement.

GoviEx will pay $4.5 million to get out of the bond by the end of the month, it said.

The developer is still working on financing the $220 million Madaouela project…..http://www.mining-journal.com/project-finance/news/1316062/toshiba-gets-out-of-goviex-deal

New Jersey’s watchdog for ratepayers watching legislation on nuclear subsidies

Nuclear Subsidies, Tax Bill Top NJ Rate Watchdog’s Agenda, By Jeannie O’Sullivan  Law360 March 2, 2018, — The New Jersey Division of Rate Counsel will be busy going to bat for utility ratepayers in the coming months by fighting legislation calling for a $300 million subsidy for Public Service Enterprise Group Inc.’s nuclear plants and hunting for savings that utilities may owe consumers in the wake of recent federal tax legislation, according to division Director Stefanie Brand.

Ratepayers can likewise count on the division to scrutinize requests by PSEG and New Jersey American Water for rate increases, according to Brand, the attorney who has… (subscribers only)https://www.law360.com/articles/1016715/nuclear-subsidies-tax-bill-top-nj-rate-watchdog-s-agenda
