Which of these safety features aims to keep nuclear radiation contained
rewona [7]

The safety feature aimed at keeping nuclear radiation contained is steel-reinforced concrete.

<h3>What is nuclear power plant?</h3>

A nuclear power plant is a building with reactors that contain controlled nuclear reactions to produce energy.

Nuclear power plants are able to generate warm water by using atomic properties of matter  (i.e.,m the process of nuclear fission), which is in turn converted into steam to move turbines.

The walls of nuclear power reactors are composed of steel-reinforced concrete in order to avoid radiation release.

In conclusion, the safety standard property that maintains nuclear radiation contained is steel-reinforced concrete.

It is not from thermodynamic energy?
prohojiy [21]

Answer:

(a) Utilization

Explanation:

Thermodynamic energy are:

<h2>(1) Kinetic energy:</h2>

Kinetic energy is that type of energy of a body which occurs due to the motion of body. Kinetic energy is always positive. In a bound system, the system remains bound as long as the kinetic energy is less than the potential energy due to the interaction of the body.

                            K.E = \frac{1}{2}mv^{2}

<h2>(2) Potential energy:</h2>

Potential energy is defined as the energy in which the energy is possessed by a body or a system for doing some work, by virtue of its position above the ground level.

Therefore,

Potential energy = PE = mgh

This potential energy is a result of gravity pulling downwards. The gravitational constant, g, is the acceleration of an object due to gravity. This acceleration is about 9.8 m s⁻².

<h2>(3) Stored energy:</h2>

Stored energy is a Potential energy.

Hence, the only energy which is not a thermodynamic energy is option (a) Utilization energy.
