Materials testing reactor

A materials testing reactor (MTR) is a high-flux research nuclear reactor aimed at studying materials exposed to a high neutron flux.

The first Materials Testing Reactor (MTR), was designed jointly by Oak Ridge National Laboratory and Argonne National Laboratory and operated in Idaho from 1952-1970.^[1][2]

Materials testing reactors include:

• BR2, the Belgian Reactor 2, moderated with a paraboloid beryllium matrix, in operation at SCK CEN since 1962.^[3]
• Dounreay Materials Testing Reactor, a Dido class reactor in the United Kingdom.
• ETRR-2, at the nuclear research center in Inshas, Egypt.
• Jules Horowitz Reactor, under construction at the Cadarache nuclear facility in southern France.^[4]
• Research reactor in Petten, the Netherlands.
• Pakistan Institute of Nuclear Science & Technology (PINSTECH) in Pakistan.
• Reactor Technology Complex of the Idaho National Laboratory in Idaho, United States.
• RV-1 nuclear reactor in Venezuelan Institute for Scientific Research, Venezuela.
• SAFARI-1, outside of Pretoria, South Africa, also used to produce medical isotopes.
• RSG G.A Siwabessy in Serpong, Indonesia
• Japan Material Testing Reactor (1968 to 2021).^[5]
