Under previously announced plans, deployment of PWRs is expected to level off at 200 GWe by around 2040, with
the use of fast reactors progressively increasing from 2020 to at least 200 GWe by 2050 and 1400 GWe by 2100.
Not exact matches
An Outdated Strategy Early nuclear engineers expected that the plutonium in the spent fuel
of thermal
reactors would be removed and then
used in
fast - neutron
reactors, called
fast breeders because they were designed to produce more plutonium than they consume.
Fast reactors can thus minimize the risk that spent fuel from energy production would be
used for weapons production, while providing a unique ability to squeeze the maximum energy out
of nuclear fuel.
Rather than the pellets
of uranium oxide
used in other
fast reactors and conventional
reactors as fuel, GE would fabricate metal alloy fuels, with the plutonium or uranium mixed with zirconium metal.
One solution under consideration is to recycle the plutonium yet further — by
using it as fuel in a pair
of new, so - called «
fast»
reactors.
Poneman said Monju came up in the discussions because
of the possibility
of using fast reactors to burn plutonium and the long - lived isotopes
of elements such as neptunium and americium that account for much
of the radiotoxicity
of nuclear waste.
One attractive feature
of fast reactors is that they can produce more fuel than they consume, avoiding the issue
of the limited supplies
of the uranium
used in conventional nuclear
reactors.
Novel design The trouble with
fast reactors has largely been related to what's
used to cool them — liquid sodium in the case
of GE's PRISM and many others.
PRISM is a sodium - cooled, high - energy neutron (
fast)
reactor design that
uses a series
of proven, safe and mature technologies developed in the U.S. and abroad.
PRISM is a high energy neutron (
fast)
reactor which
uses a series
of proven, safe and mature technologies to create an innovative solution to dispose
of used nuclear fuel and surplus plutonium.
«Unlike today's nuclear
reactor, the IFR [integral
fast reactor] can generate unlimited amounts
of inexpensive clean power for hundreds
of thousands
of years... It provides an excellent solution for what to do with our nuclear waste because it can
use our existing nuclear waste for fuel and it is significantly more proliferation - resistant than other methods
of dealing with nuclear waste... The IFR is also inherently safe.
An application case representative
of an assembly
of the low void effect sodium
fast reactor ASTRID is
used to study the physics
of this kind
of system, illustrating the interesting capabilities provided by this approach and highlighting new possible calculation schemes.
Fast reactors on a closed fuel cycle
use nearly all the actinides fed into them, while low energy
reactors use only around one percent
of the fuel.
«You get this beautiful synergy
of using PRISM, a small modular
reactor, to fix a [waste] problem and then explore if we could
use this to make all this other electricity with the integral
fast reactor approach,» he explains.
JAEA chairman Toshio Kodama said, «In addition to effectively utilizing the results
of our research and development - including the results obtained through the development
of Monju so far for future
fast reactor development - we will contribute to the development
of state -
of - the - art
fast reactors in Japan by making maximum
use of the human resources and equipment, etc
of this organization according to the established «
fast reactor development policy».»
PRISM is a high energy neutron (
fast)
reactor design which
uses a series
of proven, safe and mature technologies to provide an innovative solution to disposition plutonium stockpiles and harness the remaining energy potential
of used nuclear fuel and surplus plutonium.
Each dollar spent on a new
reactor buys about two to ten times less carbon savings and is 20 to 40 times slower, than spending that dollar on the cheaper,
faster, safer solutions that make nuclear power unnecessary and uneconomic: efficient
use of electricity, making heat and power together in factories or buildings («cogeneration»), and renewable energy.
Fast neutron
reactors are typically fuelled
using a mixture
of oxides
of uranium and plutonium, and can vastly increase the efficiency
of the nuclear fuel cycle by
using the uranium - 238 recovered from recycling nuclear fuel after
use in conventional nuclear power
reactors.
And nuclear power is just as sustainable as any other power source — even if we only
use conventional nuclear
fast reactor designs, there is enough uranium in the oceans and on land (recoverable at prices that allow the fuel costs
of fast reactors to remain the same as today — which is trivial) to last for 5 billlion years, the expected time remaining fo our sun.

Fast reactors — make maximum
use of uranium resources by generating a certain amount more fuel than they consume — are seen as the main technology for China's long - term
use of nuclear energy.
