- I asked this question once and the answer returned was correct, but I couldn't follow the work so I'm hoping you can write it more clearly: A proposed nuclear reactor facility will have an electrical power output of 805 MW with a 30.2% efficiency in converting nuclear to electrical power. Assuming the average fission reaction produces 227 MeV, how many reactions will take place at the facility every second?arrow_forwardAn accident at a nuclear power plant has left the surrounding area polluted with radioactive material that decays naturally. The initial amount of radioactive material present is 42 su (safe units), and 5 months later it is still 31 su. a.) write a formula giving the amount A(t) of radioactive material (in su) remaining after t months. (Use integers or decimals for any numbers in the expression. Round to three decimal places needed.) b.) what amount of radioactive material will remain after 11 months? c.) how long will it be until A = 1 su, so it is safe for people to return to the area?arrow_forwardWhen a star has exhausted its hydrogen fuel, it may fuse other nuclear fuels. At temperatures above 1.0 x 10° K, helium fusion can occur. Write the equation for the following processes. (a) Two alpha particles fuse to produce a nucleus A and a gamma ray. What is nucleus A? (Enter the mass number in the first raised box, the atomic number in the second lower box, and the element, with charge if necessary, in the third box.) (b) Nucleus A absorbs an alpha particle to produce a nucleus "B" and a gamma ray. What is nucleus B? (Enter your answer using the same format as above.) (c) Find the total energy (Q) released in the reactions given in parts (a) and (b). Note: the mass of 4 = 8.005 305u. MeVarrow_forward

A typical nuclear warhead releases 250,000 times more, so the yield is expressed as 250 kilotons. That is a staggering explosion, but the asteroid impact that wiped out the dinosaurs was significantly greater. Assume that the asteroid was a sphere 10 km in diameter, with a density of 2500 kg/m3 and moving at 30 km/s. What energy was released at impact, in joules and in kilotons?arrow_forwardHis case. ewent 5.

(Answer in Gray, round to the nearest single decimal place) Question 2 If 10 g of of tissue is uniformly irradiated and receives a dose of 1 cGy, what is the dose (in cGy) to half of this tissue?arrow_forwardIonizing radiation enters a Geiger tube with 1.45 MeV of energy. As the radiation passes through the tube, all of this energy goes into creating ion pairs and each ion pair requires 30 eV of energy. (a) If an applied voltage sweeps these ions out of the gas in 1.10 µs, determine the current (in A). 1.19e-8 X What is the definition of current? How many electronic charges constitute an ion pair? How can you determine the number of ion pairs created? A (b) Since the applied voltage in the Geiger tube accelerates these separated ions, creating other ion pairs in subsequent collisions, the actual current is greater than that determined in part (a). If this effect multiplies the number of ion pairs by 880, determine the actual current (in A). 1.05e-6 X How is the increase in current related to the increase in number of ion pairs? Aarrow_forwardA breeder reactor converts uranium-238 into an isotope of plutonium-239 at a rate proportional to the amount of uranium-238 present at any time. After 10 years, 0.03% of the radioactivity has dissipated (that is, 0.9997 of the initial amount remains). Suppose that initially there is 190 pounds of this substance. Find the half-life.

- We measure nuclear explosives in terms of kilotons of TNT (the bomb that destroyed Hiroshima in WWII was a 20 kiloton weapon.) 1 kiloton = 4.19 × 1012 Joules. How many Hiroshima-type bombs would you have to explode every second to equal the Sun's energy output? The purpose of this question is to illustrate that the most powerful (and destructive) things we (as a species) have created, there are things in the universe that are almost unimaginably more powerful.Number of Hiroshima-type bombs needed to equal 1 s of the Sun's energy output = _____ bombs/sarrow_forwardThis exercise uses the radioactive decay model. The half-life of radium-226 is 1600 years. Suppose we have a 29-mg sample.
