Suppose you are to downblend 2 tonnes of HEU (93% U-235) for use as commercial reactor fuel with enrichment of 4.95% U-...
The neutron-induced fission of U-235 produces Ba-140 and Kr-93, along with 3 neutrons. Use the following atomic masses: U-325: 235.04392 amu neutron: 1.00866 amu Ba-140: 139.910581 amu Kr-93: 92.931130 amu If the US needs 1.42 x 1016 kJ of electrical energy every year (for 2018 the value was 1.44 x 1016 kJ), how many kg of U-235 would have to undergo fission to supply this energy? (You can assume 100% efficiency in the conversion of energy from the fission reaction...

a) (15 p) We consider a nuclear reactor of power output P=1000 Megawatt (1000 million watts) electric, functioning with Plutonium. It is fueled, initially, with 1000 kg of Plutonium. The nuclear material in question is made of Plutonium nuclei, each 239 consisting in 94 protons and 239-94-145 neutrons, which is denominated by the symbol 94Pu. For thermodynamical rd reasons, only 1/3 of the nuclear energy in the form of heat produced by the reactor, can be converted into electricity. How...
Background You are the co-owner of a company that sells commercial 3D printers and printing parts. Your company has 10 employees and revenues of almost $40 million dollars a year. Increasingly, customers have been asking that you allow bitcoin as a payment method. Some of these customers are overseas. While you know that some of your competitors use it, all you know about it is what you’ve read in the news: that’s its popular, volatile, potentially low cost, and may...
No need to show work. Just need an answer please For Questions 15 and 16. Suppose you have an electroscope made of 2 long sheets of really thin gold leaf. People use gold because you can make very thin sheets out of it and it is an excellent conductor. The sheets are attached to a support at the top and hang down right next to each other. To use the electroscope, you put some static charge on the sheets and...
please help with whatever possible. thank you so much in advance. Name One use of serial dilutions is to calculate the concentration of microorganisms. Since it would usually be challenging or even impossible to actually count the number of microorganisms in a sample, the sample is diluted and plated to get a reasonable number of colonies to count (usually between 25 to 250 colonies is the goal). Since each colony on an agar plate theoretically grew from a single microorganism,...

Use the following information To help you solve the following questions. Show all work for thumbs up. 3.1 Rotations and Angular-Momentum Commutation Relations 159 We are particularly interested in an infinitesimal form of Ry: (3.1.4) where terms of order & and higher are ignored. Likewise, we have R0= ° :- R(E) = 1 (3.1.5) and (3.1.5b) - E01 which may be read from (3.1.4) by cyclic permutations of x, y, zthat is, x y , y → 2,2 → x....

THE WAR ON ALLERGIES SUPPOSE THAT 54.3 PERCENT of your country's population had cancer. That figure might set off a nationwide panic-a search for something wrong with people's diet, the environment, activity levels. In fact, that's the percentage of Americans who show a positive skin response to one or more allergens. A1 5 B The manifestations' of allergy-sneezing, itching, rashes-are signs of an une system running amok,2 attacking foreign invaders-allergens- that mean no harm. Allergens include pollen, dust mites, mold,...
