Question

when a uranium atoms splits in two, a few stray neutrons arc produced. if these neutrons can induce the splitting of more uranium atoms, a chain reaction results. in order to facilitate this, a nuclear reactor contains i which slows the neutrons down. ii is/are used to determine how many of these stray neutrons can continue the chain reaction. the statements above are completed correctly by the information in row ____. a decelerator; control rods a moderator; control rods a moderator; a callandria a decelerator; a callandria question 14 (1 point) the energy transformations that take place within a nuclear reactor are select one: nuclear to thermal to electrical nuclear to thermal to kinetic to electrical thermal to nuclear to kinetic to electrical thermal to nuclear to thermal to kinetic to electrical

Explanation:

Step1: Identify reactor component (i)

In nuclear reactors, the component that slows neutrons is called a moderator (not a decelerator, which is not the standard term).

Step2: Identify reactor component (ii)

Control rods absorb neutrons to regulate how many can sustain the chain reaction; a calandria is a reactor vessel component, not a neutron regulator.

Step3: Trace nuclear reactor energy flow

First, nuclear fission releases nuclear energy → this heats coolant/water to produce thermal energy → the heated fluid creates steam that drives turbines, converting to kinetic energy → turbines spin generators to produce electrical energy.

Answer:

1. a moderator; Control rods
2. nuclear to thermal to kinetic to electrical
