Ineed quickly asap what is the difference between a pressurized water reactor and a boiling water reactor? a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor indirectly heat water from the core. a pressurized water reactor does not use fission. what is true of the waste generated by nuclear power? creates acid rain causes air pollution increases greenhouse effect remains hazardous for a long time what can cause further fission reactions? protons neutrons electrons radioactivity

1. compounds a and b enter a mixer in stream 1, where they are mixed with a recycle stream (stream 5). the streams combine and exit the mixer as stream 2, which is then fed to a reactor. the reactor has the reaction 3a + b2c, and 80 % conversion (molar) of a. the unreacted a and b, as well as any c produced, exit the reactor in stream 3, which is then fed to a separator. the separator removes all of compound c produced in the reactor as stream 4, which is pure c and has a flowrate of 500 mol/hr. the remaining a and b are recycled back to the mixer as stream 5. give all flowrates in mol/hr a draw the process flow diagram. label the diagram and circle unknowns. b. determine how much c exits the reactor c. how much a and b are consumed in the reactor? d. how much a enters the reactor? e. if b is provided in 50% excess, how much b enters the reactor? f determine the total flowrates in and out of the reactor. g. find the total flowrate and composition of the recycle stream. h. determine the composition and flowrate of the fresh feed (stream 1)

Aspherical reactor composed of 239pu metal is operating in a critical steady state. discuss what probably happens to the multiplication of the reactor and why, if the system is modified in the following ways (treat each modification separately, not cumulatively): (a) the reactor is rapidly compressed to one-half its original volume, (b) a large, fat reactor operator accidentally sits on the reactor, squashing it into an ellipsoidal shape, (c) a thick sheet of hafnium is wrapped around the outside of the reactor, (d) the reactor is suddenly immersed in a large container of heavy water, (e) one simply leaves the reactor alone for 1 year.

(membrane reactor) the first order, reversible reaction a< --> b + 2c is taking place in the membrane reactor. pure a enters and b diffuses through the reactor. unfortunately, some of the reactant a also diffuses through the membrane. a. plot and analyze the flow rates of a, b and c down the reactor, as well as the flow rates of a and b through the membrane. b. compare the conversion profiles of a conventional pfr with those of a membrane reactor. what generalizations can you make? c. would the conversion of a be greater or smaller if c were diffusing instead of b? d. discuss qualitatively how your curves would change if the temperature were increased significantly or decreased significantly for an exothermic reaction. repeat for an endothermic reaction. additional info: k= 10min-1 kc=0.01mol2/dm6 kca=1min-1 kcb=40min-1 fa0=100mol/min v0 = 100dm3/min vreactor=20dm3 note that this problem only needs you to set up the system of equations, supporting equations, parameters and b.c's for ode or equivalent solver.
