What is a generic design assessment?
The ONR and the Environment Agency have developed an assessment process called Generic Design Assessment ( GDA ). The regulators use GDA to scrutinise new nuclear power plant designs and assess their acceptability for use in GB .
What is the GDA process?
Generic Design Assessment (GDA) is a process carried out by the Office for Nuclear Regulation (ONR) and the Environment Agency (EA) (the Nuclear Regulators) to assess the safety, security, and environmental protection aspects of a Nuclear Power Plant (NPP) design that is intended to be deployed in Great Britain.
What is 3rd generation nuclear reactor?
Generation III reactors (Gen III reactors) are a class of nuclear reactors designed to succeed Generation II reactors, incorporating evolutionary improvements in design.
Are RBMK reactors still used?
The World Nuclear Association lists ten RBMK reactors that are still operating in Russia (one RBMK was recently decommissioned in Saint Petersburg in 2018). Russia is now the only country with these reactors, which were designed and built by the Soviet Union. Four RBMKs are located in Kursk, a city in western Russia.
What does RBMK stand for?
The Soviet-designed RBMK (reaktor bolshoy moshchnosty kanalny, high-power channel reactor) is a water-cooled reactor with individual fuel channels and using graphite as its moderator. It is also known as the light water graphite reactor (LWGR).
How many nuclear reactors are under construction?
53 nuclear reactors
There are 53 nuclear reactors currently under construction around the world. Only two are in the United States, once the world’s leader in nuclear energy development. And those two reactors represent expansions of a preexisting two-reactor facility, Plant Vogtle in Waynesboro, Ga.
Is the core at Chernobyl still hot?
The corium of the Elephant’s Foot might not be as active as it was, but it’s still generating heat and still melting down into the base of Chernobyl.
Do RBMK reactors still exist?
There are still 11 operating RBMK reactors of the type involved in the Chernobyl accident. All of them are in Russia. Since Chernobyl, there have been significant design modifications that were recommended by the International Atomic Energy Agency (IAEA).
