A density gauge being used to ensure proper compaction for the foundation of a school construction project.. Nuclear densitometry is a technique used in civil construction and the petroleum industry, as well as for mining and archaeology purposes, to measure the density and inner structure of the test material.
The neutron absorbing materials in spent fuel pools have been observed to degrade severely over time, reducing the safety margins of maintaining subcriticality; [4] [5] [11] [2] [6] in addition, it has been shown that the in-site measurement technique used to evaluate these neutron absorbers (Boron Areal Density Gauge for Evaluating Racks, or ...
Nuclear power is a type of nuclear technology involving the controlled use of nuclear fission to release energy for work including propulsion, heat, and the generation of electricity. Nuclear energy is produced by a controlled nuclear chain reaction which creates heat—and which is used to boil water, produce steam, and drive a steam turbine.
Nuclear density is the density of the nucleus of an atom. For heavy nuclei, it is close to the nuclear saturation density n 0 = 0.15 ± 0.01 {\displaystyle n_{0}=0.15\pm 0.01} nucleons / fm 3 , which minimizes the energy density of an infinite nuclear matter . [ 1 ]
In 1967, the first nuclear gauge was developed to measure the level within a vessel at Billingham chemical works. The Specialist Measurement Instruments section was established with a variety of level, trip, and Nuclear density gauges, commonly used in applications such as slug catchers and separation vessels.
The safety equipment usually includes four basic items: a radiation survey meter (such as a Geiger/Mueller counter), an alarming dosimeter or rate meter, a gas-charged dosimeter, and a film badge or thermoluminescent dosimeter (TLD). The easiest way to remember what each of these items does is to compare them to gauges on an automobile.

Hot cells are of nuclear proliferation concern, as they can be used to carry out the chemical steps used to extract plutonium (whether weapons grade or not) from reactor fuel. [ citation needed ] The cutting of the used fuel, the dissolving of the fuel in hot nitric acid and the first extraction cycle of a nuclear reprocessing PUREX process ...
