Question

Answer the followings: (Nuclear energy, total points 20) What are different types of nuclear reactions there?0)1)2 )3 a. b. Typical purity uranium in nuclear fuel pellet is () 15% (l) 25. (w c. Typical purity uranium in nuclear bomb is ( ) 100% (ii) 20%( d. In nuclear reaction electron/proton/neutron hit the e. A nuclear power plant has name plate capacity of 1 there? (i, 1 (92 01) 3 (W) 4 fv) 5 (point 1) nucleus of an atom? (Point 1) lowe and thermal efficiency of 333)% The reactor of this power plant uses 2u as fuel. The core consists of 100 fission reaction necessary to produce this power. tons of UO; of which 4% is 235U and the remain ing is 2U. Now calculate the followings: (total points 1 (Points 5) Ans: 93.75 10 t fissions/sec ii. Molecular weight of fuel. (Points 2) Ans: 269.88 ili. Number ofisu moles in the fuel/core.(Points 3) Ans. 1428" w many full-power years could the reactor operate if all of the 235u were to be fissioned? (Points 6) Ans:3 years Hints/Clues: At the end of fission reaction, 2BU becomes U. A single fions event I 101; Avegadro's number releases 200 MeV of thermal energy, 1 eV-1.610 J Avegadro's number 6.023-10:1 releases 200 MeV of thermal energy; 1 ev-1.6
