Threat of Cyber Attacks on Nuclear Reactors and Nuclear Power Plant in India

What is a nuclear reactor?


A nuclear reactor is a system that contains and controls sustained nuclear chain reactions. Reactors are used for generating electricity, moving aircraft carriers and submarines, producing medical isotopes for imaging and cancer treatment, and for conducting research.
Fuel, made up of heavy atoms that split when they absorb neutrons, is placed into the reactor vessel (basically a large tank) along with a small neutron source. The neutrons start a chain reaction where each atom that splits releases more neutrons that cause other atoms to split. Each time an atom splits, it releases large amounts of energy in the form of heat. The heat is carried out of the reactor by coolant, which is most commonly just plain water. The coolant heats up and goes off to a turbine to spin a generator or drive shaft.Nuclear reactors are just exotic heat sources.

Main components

  • The core of the reactor contains all of the nuclear fuel and generates all of the heat. It contains low-enriched uranium (<5% U-235), control systems, and structural materials. The core can contain hundreds of thousands of individual fuel pins.
  • The coolant is the material that passes through the core, transferring the heat from the fuel to a turbine. It could be water, heavy-water, liquid sodium, helium, or something else. In the US fleet of power reactors, water is the standard.
  • The turbine transfers the heat from the coolant to electricity, just like in a fossil-fuel plant.
  • The containment is the structure that separates the reactor from the environment. These are usually dome-shaped, made of high-density, steel-reinforced concrete. Chernobyl did not have a containment to speak of.
  • Cooling towers are needed by some plants to dump the excess heat that cannot be converted to energy due to the laws of thermodynamics. These are the hyperbolic icons of nuclear energy. They emit only clean water vapor.

Animated reactor system

A nice animation of a nuclear reactor from the NRC.
The image above (reproduced from the NRC) shows a nuclear reactor heating up water and spinning a generator to produce electricity. It captures the essence of the system well. The water coming into the condenser and then going right back out would be water from a river, lake, or ocean. It goes out the cooling towers. As you can see, this water does not go near the radioactivity, which is in the reactor vessel.

What is the collegium system




The collegium system of appointment of judges is popularly referred to as judges-selecting-judges.

The collegium system was created by two judgements of the Supreme Court in 1990s in which a body of senior apex court judges headed by the Chief Justice of India selected persons and recommended their names for appointment as judges.

Under the the 22-year-old court-framed collegium system of appointment and transfer of judges of high courts and the Supreme Court, the chief justice of the respective high courts and two other senior-most judges of the court comprise a collegium empowered by virtue of a 1993 judgment of the Supreme Court to identify suitable candidates, do due diligence and recommend for appointment as judges of the court.

The shortlisted candidates are scrutinized by a collegium of five senior-most judges of the apex court headed by Chief Justice of India before being cleared for appointment. The same collegium of the apex court identifies serving judges and chief justices of high courts for elevation to the Supreme Court.

There is no mention of the collegium either in the original Constitution of India or in successive amendments.
