Kakrapar Atomic Power Station is a nuclear power station in India, which lies in the proximity of Mandvi, Surat and Tapi river in the state of Gujarat. After commissioning units 3 and 4, the power plant has become the second largest nuclear power plant in the country after the Kudankulam Nuclear Power Plant in terms of installed capacity.

Phase I

Phase I consist two 220 MW pressurised water reactor with heavy water as moderator (PHWR). KAPS-1 went critical on 3 September 1992 and began commercial electricity production a few months later on 6 May 1993. KAPS-2 went critical on 8 January 1995 and began commercial production on 1 September 1995. In January 2003, CANDU Owners Group (COG) declared KAPS as the best performing pressurised heavy water reactor. [1]

KAPS-2 was shut down after a coolant channel leak in July 2015 and a similar issue forced the shutdown of KAPS-1 in March 2016. After a replacement of coolant channels and feeder tubes, KAPS-2 attained criticality in September 2018. Maintenance on KAPS-1 was completed ahead of schedule and was brought to operation on 19 May 2019. [2]

The construction costs were originally estimated to be ₹382.52 crore; the plant was finally finished at a price of ₹1,335 crore.

Phase II

In 2007 the First Manmohan Singh ministry approved outline plans to build two Indian-designed IPHWR-700 reactors, with two sister reactors a little later at Rajasthan Atomic Power Station. In 2009 approval was confirmed, and site preparation was completed by August 2010. The first concrete for Kakrapar 3 and 4 was in November 2010 and March 2011 respectively with operation originally expected by early and late 2018 respectively. [3] [4]

The project over-ran largely due to tuning of the IPHWR-700 design and slow delivery of supplies. [3]

Unit 3 achieved the first criticality on 22 July 2020. It was connected to the grid on 10 January 2021. [5] This unit began commercial operation on 30 June 2023. [6] Unit 3 achieved operations at full load on 31 August 2023. [7]

Unit 4 was commissioned after many tests. Hot functional testing was scheduled around June 2023 and criticality was initially planned around September 2023. The Initial Fuel Loading (IFL) commenced on 20 October 2023 after permission was granted by the Atomic Energy Regulatory Board. [8] Unit 4 achieved first criticality on 17 December 2023. [9] The reactor was connected to the grid on 20 February 2024. [10] Unit 4 started commercial operation from 31 March, 2024. [11]

<span class="mw-page-title-main">Pressurized water reactor</span> Type of nuclear reactor

A pressurized water reactor (PWR) is a type of light-water nuclear reactor. PWRs constitute the large majority of the world's nuclear power plants. In a PWR, the primary coolant (water) is pumped under high pressure to the reactor core where it is heated by the energy released by the fission of atoms. The heated, high pressure water then flows to a steam generator, where it transfers its thermal energy to lower pressure water of a secondary system where steam is generated. The steam then drives turbines, which spin an electric generator. In contrast to a boiling water reactor (BWR), pressure in the primary coolant loop prevents the water from boiling within the reactor. All light-water reactors use ordinary water as both coolant and neutron moderator. Most use anywhere from two to four vertically mounted steam generators; VVER reactors use horizontal steam generators.

The Lucens reactor was a 6 MW experimental nuclear power reactor built next to Lucens, Vaud, Switzerland. After its connection to the electrical grid on 29 January 1968, the reactor only operated for a year before it suffered an accident on 21 January 1969. The cause was a corrosion-induced loss of heat dispersal leading to the destruction of a pressure tube which caused an adjacent pressure tube to fail, and partial meltdown of the core, resulting in radioactive contamination of the cavern.

Madras Atomic Power Station (MAPS) located at Kalpakkam about 80 kilometres (50 mi) south of Chennai, India, is a comprehensive nuclear power production, fuel reprocessing, and waste treatment facility that includes plutonium fuel fabrication for fast breeder reactors (FBRs). It is also India's first fully indigenously constructed nuclear power station, with two units each generating 220 MW of electricity. The first and second units of the station went critical in 1983 and 1985, respectively. The station has reactors housed in a reactor building with double shell containment improving protection also in the case of a loss-of-coolant accident. An Interim Storage Facility (ISF) is also located in Kalpakkam.

The Prototype Fast Breeder Reactor (PFBR) is a 500 MWe sodium-cooled, fast breeder reactor that is being constructed at Kokkilamedu, near Kalpakkam, in Tamil Nadu state, India. The Indira Gandhi Centre for Atomic Research (IGCAR) is responsible for the design of this reactor, the Advanced Fuel Fabrication Facility at the Bhabha Atomic Research Centre in Tarapur is responsible for MOX fuel fabrication and BHEL is providing technology and equipment for construction of the reactor. The facility builds on the decades of experience gained from operating the lower power Fast Breeder Test Reactor (FBTR). At first, the reactor's construction was supposed to be completed in September 2010, but there were several delays. The Prototype Fast Breeder Reactor is scheduled to be put into service in December 2024, which is more than 20 years after construction began and 14 years after the original commissioning date, as of December 2023. The project's cost has doubled from ₹3,500 crore to ₹7,700 crore due to the multiple delays. The construction was completed on 4th March 2024 with commencement of core loading of the reactor hence paving the way for the eventual full utilization of India’s abundant thorium reserves.

<span class="mw-page-title-main">India's three-stage nuclear power programme</span> Indias nuclear energy progamme envisioned by Homi J. Bhabha

India's three-stage nuclear power programme was formulated by Homi Bhabha, the well-known physicist, in the 1950s to secure the country's long term energy independence, through the use of uranium and thorium reserves found in the monazite sands of coastal regions of South India. The ultimate focus of the programme is on enabling the thorium reserves of India to be utilised in meeting the country's energy requirements. Thorium is particularly attractive for India, as India has only around 1–2% of the global uranium reserves, but one of the largest shares of global thorium reserves at about 25% of the world's known thorium reserves. However, thorium is more difficult to use than uranium as a fuel because it requires breeding, and global uranium prices remain low enough that breeding is not cost effective.
