What type of nuclear reactions occur in nuclear bombs?
Modern nuclear weapons work by combining chemical explosives, nuclear fission, and nuclear fusion. The explosives compress nuclear material, causing fission; the fission releases massive amounts of energy in the form of X-rays, which create the high temperature and pressure needed to ignite fusion.
Which type of reaction occurs in the core of a nuclear reactor in a nuclear power plant quizlet?
The reactor vessel is where the control rods and the fuel rods are placed and is where nuclear fission occurs. The heat released by nuclear fission heats water and changes it to steam in the heat exchanger.
What is a nuclear reaction in chemistry?
nuclear reaction, change in the identity or characteristics of an atomic nucleus, induced by bombarding it with an energetic particle. … In any case, the bombarding particle must have enough energy to approach the positively charged nucleus to within range of the strong nuclear force.
What 2 chemicals are in the atomic bomb?
Two atomic bombs made by the allied powers (USA and UK) from uranium-235 and plutonium-239 were dropped on Hiroshima and Nagasaki respectively early in August 1945. These brought the long Second World War to a sudden end. The immense and previously unimaginable power of the atom had been demonstrated.
How do nuclear reactors and nuclear bombs differ in how they control the reaction?
Control of Nuclear Fission
One main difference between the two is that the fission events in a reactor are monitored and controlled closely. An atom bomb is an uncontrolled fission chain reaction, that releases exorbitant amounts of energy quickly. The design of a nuclear reactor includes control rods.
How was the first nuclear chain reaction made?
A single random neutron was enough to start the chain reaction process once the physicists assembled CP-1. The first neutron would induce fission on a uranium nucleus, emitting a set of new neutrons. … Sometimes, a few seconds after the fission occurs in a nuclear chain reaction, additional neutrons are released.
