List of abbreviations adopted in nuclear power engineering

The purpose of this handbook is to offer one possible way of deciphering these abbreviations; some of them may have two or more interpretations.

I started compiling this list before moving to Finland, back then it consisted mostly of Russian acronyms.

In 2016 I continued it while working on the construction of the nuclear power plant Olkiluoto 3 .

At that point the English-language section was increased several times over.

I have not encountered some of the suggested abbreviations in practice.

Bq 1 bequerel = 1 nucleus decay per second * Becquerel
* The becquerel (symbol Bq) is the SI derived unit of radioactivity. One becquerel is defined as the activity of a quantity of radioactive material in which one nucleus decays per second. The becquerel is therefore equivalent to an inverse second, s−1. The becquerel is named after Henri Becquerel, who shared a Nobel Prize in Physics with Pierre and Marie Curie in 1903 for their work in discovering radioactivity

Ci 1 Curie = 3.7 × 10^10 decays per second (37 GBq) * Curie
* "The curie (symbol Ci) is a non-SI unit of radioactivity, named 'in honour of' Pierre Curie, according to his widow, the famed radiation researcher Marie Curie.

It was originally defined as ""the quantity or mass of radium emanation in equilibrium with one gram of radium (element)"" but is currently defined as: 1 Ci = 3.7 × 1010 decays per second after more accurate measurements of the activity of 226Ra (which has a specific activity of 3.66 x 1010 Bq/g.[3])

In 1975 the General Conference on Weights and Measures gave the becquerel (Bq), defined as one nuclear decay per second, official status as the SI unit of activity. Therefore: "

RCP Reactor Coolant Pump *
"The RCPs are part of the Reactor Coolant System (RCS); they are located in the cold leg of each of the four primary loops. RCPs are essential mechanical components for the reactor’s safety. They provide with a constant flow a forced circulation of water through the RCS. This water circulation removes heat from the reactor core to the steam generators. The steam produced by the steam generators is then transferred to the turbine island and actuates the turbine to generate electricity. "
