+WS 6.6 – Nuclear ReactorsDon Showalter’s Miniature Evil Twin Brother (we’ll simply call him “Mini-Walter”) has erased key termsdescribing the function of a nuclear power plant. Fill in the blanks by choosing from the answer bank below.Choose wisely!In a nuclear reactor, ____________ undergoes nuclear ____________ when struck by____________. This reaction releases many more ____________ which are capable of splittingmany more ____________ atoms. If this ____________ is not controlled, it could cause a____________. To prevent this, ____________ are used to absorb ____________, thusreducing the number available to cause ____________. A metal such as ____________ is oftenused for this, unlike ____________ which can vaporize at high temperatures.In the primary cooling system, water absorbs ____________ from the ____________, andtransfers it to the ____________ which is part of the secondary cooling system. The water in the 1°cooling system also helps to regulate the ____________ of the reactor core.In the secondary cooling system water is changed into ____________ by absorbing____________ from the ____________. Once changed, the ____________ can turn a____________ which operates a ____________, and this is what creates ____________.Eventually, the ____________ will have to be changed back into water by the tertiary coolingsystem.In the tertiary cooling system, water from a ____________ may be used to absorb heat fromthe ____________ which is in the 2° cooling system. Once the water in the 3° is hot, it is sent to a____________ before being returned to the ____________.==== Answers: In Alphabetical Order + 7 === Cross Them Off As you Find Them! ====1° water system / 3° water system / carbon / cadmium / chain reaction / cobalt/ condenser / control rods / cooling tower / electricity / explosion / fission /fission / generator / heat / heat / isotopes / meltdown / moderator /neutrons / neutrons / neutrons / reactor core / river / river / steam /steam / steam / steam / steam generator / temperature / turbine / U-235/ U-235 / U-2381° water
