Amolten salt reactor using thorium-232 as a blanket and uranium-233 as the fuel is being planned to run entirely off of the u-233 produced from the blanket. it is currently being fueled only by u-235. because the th-232 in the blanket can be pumped continuously from the blanket surrounding the core, pa-233 can be extracted before any radiative capture can occur, thereby removing any losses of pa-233 due to neutron absorption. the pa-233 is stored in a container and the u-233 is accumulated outside the core. a. write down the nuclear reactions that will lead to the production of u-233 from the neutron capture of th-232. why can you ignore th-233 for the rest of this problem? b. set up the rate equations you would use to analyze the pa-233 and u-233 content over time. c. how much th-232 would be needed produce 200 kg of u-233 fuel from the blanket in one year? you can keep your answers in terms of number of atoms. q = 1014 neutrons/cm² s oc of th-232 = 8 barns

An air bubble of volume 20 cm³ is at the bottom of a lake 40 m deep, where the temperature is 4.0°c. the bubble rises to the surface, which is at a temperature of 20°c.take the temperature of the bubble’s air to be the same as that of the surrounding water. just as the bubble reaches the surface, what is its volume?

5submission this assignment is worth 20 points total. you are required to submit the following by next lab: 1. (3 points) determine the equation for the output angular velocity ω2 = θ˙ 2 as a function of θ1, ω1 = θ˙ 1 and α. you must show all your work to receive credit. 2. (2 points) use the result of problem#1 to plot ω2 over 0 ≤ θ1 ≤ 360deg with ω1 = 360deg/sec. do this for α = {10,30}deg. show the results on the same plot and properly label the axes, title, legend. for this you can use matlab or ms excel. 3. (3 points) determine the equation for the output angular acceleration ω˙ 2 and create a plot similar to the one in problem#2. 4. (10 points) submit plots of the results (ω2 and ω˙ 2) obtained from creo/mechanism and compare them to results of problem#2 and problem#3. note that you should do these comparisons for the two cases with α = {10,30}deg. 5. (2 points) provide a brief explanation of the results. did they match? what are the implications as misalignment angle increases?
