Example 6 reveiws the principles that play a role in this problem. A nuclear power reactor generates 4.3 × 109 W of power. In one year (365.25 days), what is the change in the mass of the nuclear fuel due to the energy being taken from the reactor?

Solutions

Expert Solution

P = power = 4.3 x 10⁹ Watt

t = time = 1 year = 365.25 days = 365.25 x 24 x 3600 = 3.156 x 10⁷ sec

E = energy = Pt = 4.3 x 10⁹ x 3.156 x 10⁷

m = change in mass

c = speed of light = 3 x 10⁸ m/s

E = m c²

4.3 x 10⁹ x 3.156 x 10⁷ = m (3 x 10⁸)²

m = 1.51 kg

A nuclear power reactor produces 3GW of thermal power from the fission of 235U for a period of 10 weeks and then it is shut down. Note: All numerical answers are expected with 3 significant figures. (a) Assuming 78% of the 200MeV released per fission event is converted to heat, estimate the number of 235U nuclei fissioned over the 10 week period. (b) 6 % of the 235U fission events produce as a fission fragment some radioactive nuclide X (e.g....

Electrical power is to be produced from a steam turbine connected to a nuclear reactor. Steam is obtained from the ractor at 540 K and 36 bar, the turbine exit pressure is 1.0 bar, and the turbine is adiabatic. a) Compute the maximum work per kilogram of steam that can be obtained from the turbine. A clever chemical engineer has suggested that the single-stage turbine considered here be replaced by a two-stage adiabatic turbine, and that the steam exiting from...

A nuclear power plant based on the Rankine cycle operates with a boiling-water reactor to develop net cycle power of 3 MW. Steam exits the reactor core at 100 bar, 620°C and expands through the turbine to the condenser pressure of 1 bar. Saturated liquid exits the condenser and is pumped to the reactor pressure of 100 bar. Isentropic efficiencies of the turbine and pump are 81% and 78%, respectively. Cooling water enters the condenser at 15°C with a mass...

Problem 2. A nuclear power plant produces radioactive waste as a byproduct. One such byproduct is an isotope of the noble gas Krypton, 36Kr85, which decays via ?- decay with half-life T1/2 = 10.8 yrs. Each decay releases a ?- particle with energy = 0.240 MeV (on average). This energy is converted into thermal energy as the particle interacts with the surrounding particles. SHORT QUESTIONS. 2 pts each.
