It s sealed like a pressure cooker. So there is no way for a person to fall in an operating nuclear reactor. Only a very few small research reactors have open pools of water the vast majority of reactors today have water under very high pressure.
While powering a nuclear reactor these fuel rods become very very hot 2 800 degrees celsius. Spent nuclear fuel pools are designed to cool fuel rods after they come out of a nuclear reactor. This is an incomplete list.
List of nuclear power stations this is a list of major nuclear power plants in all countries in the world. To see those in the wikipedia. Commercial pressurized water reactor pwr nuclear power plants a complete list of nuclear reactors can be found at list of nuclear reactors.
The list is not complete u s. The reactor core sits under 19 feet of water on a grid plate suspended from a movable bridge above the pool. The reactor pool contains 32 000 gallons of high purity water and is 9 feet wide 19 feet long and 27 to 30 feet deep.
The reactor a 200 kilowatt swimming pool type nuclear reactor has been in operation since 1961. I have seen with my own eyes commercial divers swimming in a spent fuel pool with fuel in it installing high density fuel racks in place of the original density fuel racks after it became clear that the us government was going to renege on its ob. With the completion of this new type reactor in 1950 it became apparent that a solution had been found to allow a wide number of small reactors to be built once allowed by the changes to the atomic energy.
In many cases pool reactors were referred to as swimming pool reactors a fairly appropriate identification if not an invitation. In the cooling system cooling water is passed over the fuel elements within casings in mutually opposite directions and then collected cooled decontaminated and returned to the. A cooling system for a swimming pool reactor is designed which maintains the versatility and accessibility of the reactor while enabling its power to be increased.
Such pools are used for immediate cooling of the fuel rods which allows short lived isotopes to decay and thus reduce the ionising radiation emanating from the rods.
Nuclear reactor pool swim. Pool type reactors also called swimming pool reactors are a type of nuclear reactor that has a core consisting of the fuel elements and the control rods immersed in an open pool of usually water. Some sodium cooled reactors like the bn 600 have sodium pools instead. The rest of this article will assume that water is being used. The water acts as neutron moderator cooling agent and.
We know spent fuel pools can be safe to swim in because they re routinely serviced by human divers. However these divers have to be careful. On august 31st 2010 a diver was servicing the spent fuel pool at the leibstadt nuclear reactor in switzerland. He spotted an unidentified length of tubing on the bottom of the pool and radioed his.
A reactor s local pool is specially designed for the reactor in which the fuel was used and is situated at the reactor site.
