8. A fresh spent nuclear fuel was removed from a reactor core and placed into a spent fuel pool. One of the activation products in the nuclear fuel was Cobalt (Co-60). After 8 year of storage in the pools, the activity of the Co-60 was reduce to 0.5x105 Ci. Please determines: i)The initial activity of the Co-60 at the day when the spent nuclear fuel was stored in the pool. [Given that half-life, t1/2 of the Co-60 is 5.26 yr]...

A 1000 MWe nuclear reactor (5% U-235 fuel) has been operating at 100% power for 10 continuous days. On day 10, reactor power is brought down to 100MWe to load follow the power grid. After holding at 100MWe for 24 hours, the reactor starts to lose power. Despite additional removal of control rods, the reactor power continues to drop. a) What is causing the reactor to lose power? b) What steps can be done to correct this issue in the...

(if appropriate)
A spherical nuclear fuel pellet consists of a uranium core (thermal conductivity ku) of radius R with uniform internal energy generation q, surrounded by a layer of protective cladding (thermal conductivity ke) that does not have internal energy generation but has a thickness of t. The pellet is immersed in a large fluid bath with a temperature To and convection coefficient h. (a) Starting from the heat diffusion equation in...

QUESTION 1 239 a) (15 p) We consider a nuclear reactor of power output P-1000 Megawott (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 consisting in 94 protons and 239-94-145 neutrons, which is rd denominated by the symbol 94 Pu For thermodynamical reasons, only 1/3 of the nuclear energy in the form of heat produced by the reactor, can...
