ANSWER: Neither 1 nor 2
Explanation:
- Akin to the Richter scale, used to quantify the severity of an earthquake, the International Nuclear and Radiological Event (INES) scale is developed by the International Atomic Energy Authority.
- It has seven-rung classification scheme internationally used to rate the severity of nuclear mishaps.
- It rates a Level 1 as only akin to ‘an anomaly in the plant.’ Levels 1-3 are termed ‘incidents’ and 4-7 as ‘accident.’ By comparison, the nuclear accidents in Fukushima, Japan, in 2011 and Chernobyl, Russia, in 1986 were Level 7 incidents.
- Recently in Kakrapar Nuclear Power plant, one of the pipes carrying heavy water ruptured and led to leakage on the floor of the reactor building. Moreover, the leak occurred in a subsystem that had been refurbished with better quality material in 2011, as part of a planned upgrade.
- The leak has been classified as level 1 incidence.
