Question
Can someone explain this to me? I obviously have the answer, but I need to understand why the terms are defined as what they are. Why is the energy produced in the reactor Qp? Why is the steam exchanger Qo? Why does it seem like they are pumping additional heat into the reactor to meet the demands of the heat exchanger generating steam? Why does that not defy the basic operational principles of a nuclear reactor? Can someone please help me get a grasp on the setup here?
6. A nuclear facility is to be studied as a complete system. The heat produced by the heat source is 1.36 10 Btu/hr. The heat removed by the heat exchanger steam generator) is 10 Btu/hr. What is the required pump power to maintain a stable temperature? (1 2,544.43 Btu/hr)Explanation / Answer
The basic principle of nuclear power plant is same as of the steam power plant. Tha basic difference is only that in nuclear station we use nuclear fission process for heat generation process instead of coal in steam power plant.
Nuclear fission is the process in which heavy radioactive atoms are broken into two nearly equal parts.
Given:
Qp (Heat produced by nuclear fission process) = 1.360 x 1010 Btu/hr
Qo (Heat output by the plant) = 1.361 x 1010 Btu/hr
Ihp = 2544.43 Btu/hr
As we Know that
heat produced by source + work done = Heat output
Qp + W = Qo
W = Qo - Qp
W = 1.361 x 1010 - 1.360 x 1010
W = 0.001 x 1010
W = 1 x 107 Btu/hr
So we required a pump who able to produce/pump 1 x 107 btu of energy per hour or in terms of Hp
W = 1 x 107 / 2544.43
W = 3930.15 Hp
so we required a pump of power 3930.15 Hp
we required a pump because the heat source is lonely not able to produce a demand heat so thats why we required a additional pump to meet a demand.
