breeder

core
▪
To protect power station workers from this invisible threat the reactor core has to be encased behind many metres of thick concrete.
▪
Radioactivity is induced in the metallic containment vessel that surrounds a reactor core by neutrons that escape from the core.
▪
During the last 30 years there have been 12 accidents around the world that have caused serious damage to a reactor core .
▪
The accident, which occurred on August 13, did not involve the release of radiation or damage to the reactor core .
▪
Leaks in primary circuits distributing heat from the reactor core would be uncontrollable, leading to a core meltdown.
▪
The reactor core erupted in a gigantic explosion, spewing enormous amounts of heat and disintegrated radioactive fuel into the atmosphere.
fuel
▪
Since Pu acts like U, the end result is quite like the low-enriched uranium used as reactor fuel .
▪
It is clear that steps must be taken to prevent reactor disposal of this material from stimulating reprocessing of commercial reactor fuel .
fusion
▪

▪
At the same time, they would work with us on the direct disposal of this material without using reactors .
▪
Indigenous microorganisms are now used in above-ground batch reactors , but commercial blends are being used to degrade petroleum hydrocarbons.
▪
The penalty for using a reactor is that we must carry the weight of the reactor and its associated radiation shielding.
▪
Plutonium is not found naturally on earth, but it is produced whenever uranium is used in a nuclear reactor .
▪
