One reactor year refers to the operational time during which a nuclear reactor generates electricity for one complete year at full power. It is commonly used as a unit of measurement in the nuclear industry to quantify reactor performance and is equivalent to 8,760 hours of operation. This metric helps in assessing the reactor's output, maintenance needs, and overall efficiency over time.
a completely mixed reactor. the concentration in the reactor is the same that flows our of the reactor
A 1000 MW nuclear reactor typically uses about 25 to 30 tons of uranium fuel per year. This equates to approximately 68 to 82 kilograms of uranium consumed per day, depending on the reactor's efficiency and operational conditions. The exact amount can vary based on the reactor design and the enrichment level of the uranium used.
Leo Szilard invented the nuclear reactor in 1933, but did not build it.Enrico Fermi built first nuclear reactor, CP-1 in 1942.Walter Zinn built the first nuclear power plant, EBR-1 in 1951.
You may mean FBR - this stands for Fast Breeder Reactor
Experimental Breeder Reactor I was created in 1950.
The first nuclear reactor was in former Soviet Union that operated in year 1954 at obninisk.
The quantity depends on: the type of the reactor, power of the reactor, enrichment of uraniu, chemical form of the fuel, etc. For a research reactor some kilograms, for a power reactor more than 100 tonnes/year.
The first ever reactor was in 1942, but not power producing. The first electric power producing reactor was in the UK in 1956
The first nuclear reactor, CP-1, was built and operated in 1942. It generated no electricity, its peak thermal power was one half watt. The first nuclear power plant was connected to the grid sometime in the 1950s.
CP-1, Chicago Pile #1
1986, the same year as the Challenger Space Shuttle explosion.
1. Dhruva reactor: http://en.wikipedia.org/wiki/Dhruva_reactor This reactor is a larger version of CIRUS and can produce up to 25 KG of plutonium per year. No statement has been made about shutting down this reactor, presumably India feels it is not obliged to because unlike CIRUS it was designed and built using Indian resources. 2. CIRUS reactor http://en.wikipedia.org/wiki/CIRUS_reactor. The CIRUS design is based on Canada's Chalk River reactor and was built with Canadian help. India has announced that this reactor will be shutdown in 2010 in accordance with the terms of the recent US-India nuclear deal. CIRUS can produce up to 10 kg of plutonium in a year. 3. KAMINI reactor http://en.wikipedia.org/wiki/KAMINI 4. APSARA reactor http://www.barc.ernet.in/webpages/about/mile.htm
The lifespan of a kilogram of uranium inside a nuclear reactor depends on the type of reactor and its operating conditions. Typically, a kilogram of uranium in a reactor can generate energy for several years before needing to be replaced or refueled. The amount of energy generated also depends on the efficiency and design of the reactor.

The first fatal reactor accident in the US was the SL-1 Boiling Water Reactor in Idaho in 1961. See link for details. There were earlier minor accidents at other reactors. Chalk River, Ontario NRX Reactor in 1952. See link for details.
the boiling water reactor, pressurized water reactor, and the LMFB reactor
Depends on the size and power rating of the reactor. Some low power experimental reactors like CP-1 (first reactor in the world) and CP-2 (made from parts of CP-1 after it was shutdown) have none at all. CP-1 never operated at more than 1/2 watt power at any time.
