Consolidated Edison's Indian Point No. 2 reactor is designed to operate at a power of 2,758 MW (thermal). Assuming that all fissions occur in 235U, calculate in grams per day the rate at which 235U is

(a) fissioned,

(b) consumed.

what is the total accumulated activity of the fission products in the Indian Point No. 2 reactor I day after shutdown following 1 year of operation?

a) The rate at which ²³⁵U is fissioned is 2896 g/day

b) The rate at which ²³⁵U is consumed is 3385.31 g/day

Explanation:

a) When ²³⁵U is fissioned:

The fission of burn up rate is equal to:

F = 1.05 gP = 1.05 * 2758 = 2896 g/day

b) When ²³⁵U is consumed:

The comsuption rate is:

C = 1.05*(1+α)*gp, where α = 16.9 for ²³⁵U

C = 1.05*(1 + (16.9/100)) * 2758 = 3385.31 g/day

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

so here is the information for current research:

-nrel's geothermal analysts, scientists, and engineers perform a full range of research from developing advanced methods of locating and accessing geothermal resources to exploring innovative technologies to extract and produce clean energy from the heat of the earth

and here is the information for the technology of geothermal energy:

-it's clean and sustainable

-resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma

-almost everywhere, the shallow ground or upper 10 feet of the earth's surface maintains a nearly constant temperature between 50° and 60°f (10° and 16°c)

-geothermal heat pumps can tap into this resource to heat and cool buildings

-a geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building

-in the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system

-in the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger

-the heat removed from the indoor air during the summer can also be used to provide a free source of hot water
