Mass and Volume of Spent Nuclear Fuel – NRC Response
I recently wrote a post on the Mass and Volume of Spent Nuclear Fuel. Roberto Kersevan pointed out in a comment that the Nuclear Regulatory […]

Mass and Volume of Spent Nuclear Fuel
I frequently hear comments about the amount of spent nuclear fuel for a certain amount of energy. One figure is that it is one pound […]

‘Burning’ Nuclear Waste in Nuclear Reactors
I was recently asked for my opinion on the DUPIC (Direct Use of spent PWR fuel In CANDU) reactor. Although I do not have any […]

Spent Fuel Pools – Sizewell/Hinkley and Fukushima Unit 4
Originally I was going to write something just about Fukushima Unit 4 Spent fuel pond. There has been some reports about ‘the end of civilisation’ […]

Deep Geological Repository
It is planned that the spent fuel from Sizewell C&D will be moved to a final ‘geological repository’ in about 21301. At a recent consultation […]

Terrorist Attacks on Spent Nuclear Fuel Ponds
In my previous blog I talked about the amount of spent fuel and in particular Caesium 137 that will possible stored at Sizewell if the […]

Sizewell Nuclear Waste Dump
Unlike Sizewell A the waste from Sizewell B and from the proposed Sizewell C&D are to be stored on site until at least 21301. This […]

Cs-137 Inventories in Spent Fuel
In my previous post, I showed a method of getting a rough idea about how much Cs-137 there is in spent fuel as it leaves […]

Cs-137 in Spent Fuel as it leaves the reactor
I am now going to get a rough idea of how much caesium 137 there is in spent nuclear fuel. One reason for choosing Cs-137 […]

Production and Decay of Fission Products
We are going to assume that the fissile product has one mode of decay and does not do anything naughty, such as undergo neutron capture. […]

Composition of Spent Fuel
The fuel in modern nuclear power plants is enriched to 3-5% U-235 (which is the isotope that undergoes fission). Therefore we might expect that spent […]

Implications of High Burnup Fuel – Basic Notes
An important issue around nuclear new build is the amount and what happens to the spent fuel. The proposed EPR reactors at Sizewell and Hinkley […]

Spent Fuel – Basic Notes
These are just a few basic notes about spent fuel waste from nuclear power stations. It assumes a basic understanding of the nuclear fission process […]

Uranium Enrichment Formula
This is another one of those background information posts deriving the mass balances for uranium enrichment. Let us consider the following enrichment scenario: We have […]

3500 Tonnes of Spent Fuel may be produced by Sizewell C
I previously did a rough calculation about the amount of spent fuel waste that is going to be generated by Sizewell B (see Spent Fuel […]

US Legal Challenge to Onsite Waste Storage
A Federal Appeal Court in the USA has ruled that nuclear regulators did not fully assess the risks associated with allowing utilities to store their […]

Over 1000 Tonnes of Nuclear Waste To Be Stored At Sizewell B
Over 1000[1] Tonnes of Nuclear Waste To Be Stored At Sizewell BDespite over 60 years of producing highly radioactive waste we still have no way […]
-
Spent Fuel At Sizewell B
This is my calculation of the amount of spent fuel at Sizewell B. It is not that accurate (estimate 20% either side) but should give […]
