An apparatus, such as a large fermentation chamber, for growing organisms such as bacteria or yeast that are used in the biotechnological production of substances such as pharmaceuticals, antibodies, or vaccines, or for the bioconversion of organic waste.
Reactors are vessels specifically designed for carrying out chemical reactions, often with controlled conditions such as temperature and pressure. Vessels are generally containers that can hold a variety of substances, including reactors. Reactors are a type of vessel that is specialized for chemical processing.
In 1973 nuclear power in France was at a cross-roads. The earlier gas cooled graphite reactors (eight were built), similar to the magnox design in the UK, were clearly not adequate for future power demands, and decisions were made to follow the PWR route in future. I do not have details of when these eight reactors were shutdown, but they existed in 1973. There was also a small PWR at Chooz, of 310 MWe output, and there was a prototype fast reactor Phenix of 250 MWe. Superphenix came later. So the simple answer was ten reactors (that is power reactors, excluding small research reactors)
Enzyme.
The type of molecule that is an enzyme is a protein molecule.
Enzyme activators like cofactors or substrates can switch on enzyme activity by binding to the enzyme and promoting its function. Conversely, inhibitors can switch off or reduce enzyme activity by binding to the enzyme and preventing its normal function.

No. Our reactors are fission reactors. We haven't yet mastered fusion reactors for power.
There are several types of nuclear reactors, with the most common being pressurized water reactors (PWRs) and boiling water reactors (BWRs). Other types include heavy water reactors (HWRs), gas-cooled reactors (GCRs), and fast breeder reactors (FBRs). Additionally, there are specialized reactors like research reactors and small modular reactors (SMRs). In total, there are more than a dozen distinct reactor designs used for various purposes worldwide.
Most nuclear reactors are thermal-neutron reactors. A few fast breeder reactors have been built, but not many.
No, at least not for power reactors
Yes, stars are fusion reactors.
As of 2021, there are around 440 nuclear reactors in operation worldwide. These reactors are used for generating electricity through nuclear fission reactions. The number of reactors changes over time due to construction of new reactors and decommissioning of old ones.
Nuclear reactors use nuclear fission.
The US with 100 (I am uncertain if this is all reactors or just power reactors though, there are several small reactors operated to make medical isotopes, etc. or for research purposes of various kinds).
Nuclear reactors use controlled nuclear fission reactions to generate heat, which is then used to produce steam that drives turbines to generate electricity. The heat is produced in the reactor core where nuclear fuel rods containing uranium or plutonium undergo fission reactions. The reactor's cooling system helps regulate the temperature and prevent overheating.
There are over 400 nuclear reactors around the world.
there are no bad things about the nuclear power reactors
