When was the NRX created?

July 1947
During this time, a nuclear laboratory was established at Chalk River, Ontario, and, in July 1947, Canada’s first experimental reactor — the NRX, or National Research Experimental — was built for a wide range of nuclear-energy research purposes, as well as potential civilian and military applications.

Where was the first nuclear reactor in Canada?

Ontario
In 1962 Canada’s first nuclear power plant, the Nuclear Power Demonstration Plant, was opened at Rolphton, Ontario. This plant demonstrated all-important principles for the CANDU design of reactor.

What happened at Chalk River?

CHALK RIVER, Ontario — At 3:07 p.m. on Friday, Dec. 12, 1952, the National Research Experimental nuclear reactor, then the most powerful research reactor on Earth, raced out of control, rapidly overheated and exploded, destroying the reactor core and spewing radioactive gases and debris into the atmosphere.

What Heavy water is used for in the National research Universal NRU reactor at the Chalk River Laboratories in Chalk River Ontario?

A small, prototype reactor, it was built to demonstrate that uranium and heavy water could be used for nuclear fission and that plutonium could be produced and extracted from the process for military applications.

Where did the Chalk River accident happen?

OVERVIEW. On December 12, 1952, a partial meltdown of the NRX reactor core at Chalk River, Ontario, occurred. The causes of the accident provide insight for more recent events.

Are Candu reactors still being built?

Because Canada has a record of excellence in nuclear technology, other countries have built these Canadian-designed reactors. Almost half of CANDU reactors have been built in Argentina, China, India, Pakistan, Romania and South Korea. There are 34 CANDU reactors globally, 30 of which are operable.

What is Chalk River famous for?

The NRX reactor in Chalk River holds the distinction of having the world’s first meltdown of a nuclear reactor. In 1952, a loss of coolant caused uranium rods to overheat. This resulted in a massive hydrogen explosion and the leakage of tonnes of radioactive water.

When did Chalk River shut down?

The reactor at the Chalk River site ceased production in October 2016, but had since remained on standby. Operator Canadian Nuclear Laboratories (CNL) announced yesterday that the reactor had been “quietly shut down for the last time” at 7.00pm on 31 March.

How many people work at Chalk River Laboratories?

As Canada’s national nuclear laboratory, CNL employs over 3,000 professionals in a variety of unique fields, from nuclear scientists and engineers to business professionals and skilled tradespeople.

Who owns CNL chalk?

federal crown corporation Atomic Energy of Canada Limited
The National Research Council of Canada nuclear laboratory was transferred to the newly-incorporated federal crown corporation Atomic Energy of Canada Limited (AECL). NRX suffers a major accident but is rebuilt and restarted within 14 months.

What was the power rating of the NRX reactor?

NRX (National Research Experimental) was a heavy-water-moderated, light-water-cooled, nuclear research reactor at the Canadian Chalk River Laboratories, which came into operation in 1947 at a design power rating of 10 MW (thermal), increasing to

When did the NRX Nuclear power plant shut down?

NRX operated for 45 years, being shut down permanently on 30 March 1993. It is currently undergoing decommissioning at the Chalk River Laboratories site. NRX was the successor to Canada’s first reactor, ZEEP.

Where was the National Research Universal reactor located?

From Wikipedia, the free encyclopedia (Redirected from National Research Universal Reactor) Coordinates: 46°3′15.53″N 77°21′52.12″W The National Research Universal (NRU) reactor was a 135 MW nuclear research reactor built in the Chalk River Laboratories, Ontario, one of Canada ’s national science facilities.
