Determine the power (in watts) that the reactor generates.
Number______ Units_____.
Another series of nuclear reactions that can produce energy in the interior of stars is the cycle described below. This cycle is most efficient when the central temperature in a star is above 1.6 x107 K. Because the temperature at the center of the Sun is only 1.5 x 107 K, the following cycle produces less than 10% of the Sun’s energy. (a) A high - energy proton is absorbed by 12C. Another nucleus, A, is produced in the reaction, along with a gamma ray. Identify nucleus A. (b) Nucleus A decays through positron emission to form nucleus B. Identify nucleus B. (c) Nucleus B absorbs a proton to produce nucleus C and a gamma ray. Identify nucleus C . (d) Nucleus C absorbs a proton to produce nucleus D and a gamma ray. Identify nucleus D. (e) Nucleus D decays through positron emission to produce nucleus E. Identify nucleus E. (f ) Nucleus E absorbs a proton to produce nucleus F plus an alpha particle. What is nucleus F? Note: If nucleus F is not 12C— that is, the nucleus you started with —…

- We want to get an idea of the actual mass of 235U involved in powering a nuclear power plant. Assume that a single fission event releases 200 MeV of thermal energy. A 1,000 MWe electric power plant has a thermal power of approximately 3,000 MWth. What rate of fission reactions is required to produce this power? (Note: 1 eV = 1.6 × 10−19 J.) The reactor core consists of approximately 100 tonnes of UO2 (1 tonne = 1,000 kg), which is enriched in 235U to 4%. How many full-power years could the reactor operate if all of the 235U were to be fissioned? What factors prevent such complete depletion of the 235U from occurring?

- The unified atomic mass unit, denoted u, is defined to be 1 u = 1.6605 × 10-27 kg. It can be used as an approximation for the average mass of a nucleon in a nucleus, taking the binding energy into account. How much energy, in megaelectron volts, would you obtain if you completely converted a nucleus of 19 nucleons into free energy?arrow_forwardMost of the energy released in the collapse of a massive star to a neutron star (a core collapse supernova) is in the form of neutrinos. If the just-formed neutron star has a mass M = 1.4M⊙ and a radius R = 10 km, estimate the mean nucleon density, in cm−3.
