how is the energy of a nuclear reactor converted to electricity?

a)the nuclear reactions produce electrical energy directly.
b)heat powers an electrical generator directly.
c)steam converts mechanical energy to electricity.
d)reactor products charge huge batteries.

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
