KAPP-4 Achieves Critical Status, Boosts India’s Energy Independence

KAPP-4 Achieves Critical Status, Boosts India’s Energy Independence

KAPP-4 Independence

Significance of KAPP-4’s successful operation

The Kakrapar Atomic Power Project (KAPP-4) in Gujarat marked a significant event as its fourth unit, boasting a 700 MWe capacity, commenced a controlled fission chain reaction and achieved critical status at 1.17 am on December 17. This successful milestone in the power plant’s operation places India one step closer to enhancing its energy independence and solidifying its position as a leader in atomic energy. With KAPP-4 now operational, the nuclear power facility’s overall capacity has increased, paving the way for stable electricity provision and sustainable development in the region.

Kakrapar Atomic Power Station’s reactors

Situated roughly 80 km from Surat, the Kakrapar Atomic Power Station currently operates two pressurized heavy water reactors (PHWRs) with 220 MWe capacities each. The recently deployed 700 MWe units, constructed by the Nuclear Power Corporation of India Limited (NPCIL), stand as the nation’s largest indigenous nuclear power reactors. These new units contribute significantly towards India’s energy production, whilst also showcasing the country’s capability and commitment to nuclear power innovation. Furthermore, the incorporation of advanced safety features and better fuel efficiency highlights the modernization of India’s nuclear infrastructure.

Unit-3 and the benefits of Pressurized Heavy Water Reactors

KAPP’s Unit-3 started producing commercial electricity from August 30, displaying swift progress in bringing the advanced indigenous reactors into operation. These PHWRs utilize natural uranium as fuel and heavy water as a coolant and moderator. The successful implementation of these Pressurized Heavy Water Reactors (PHWRs) showcases India’s growing expertise in nuclear technology and its strides towards self-reliance in energy generation. This also emphasizes India’s commitment to environmentally friendly energy sources, given the fact that nuclear energy provides an effective means of electricity production with minimal greenhouse gas emissions.

Indian industries’ contributions to the project

Indian industries assisted in the project’s development by providing equipment and fulfilling contracts for both reactors. Their contributions not only streamlined the construction process but also boosted the local economy by creating job opportunities and promoting technological advancements. Their collaborative efforts helped ensure timely completion of the project while fostering a sense of pride in the nation’s nuclear capabilities.

Atomic Energy Regulatory Board’s confirmation

The successful commissioning of the reactor was confirmed by the Atomic Energy Regulatory Board (AERB) after it satisfied all predetermined conditions. This marks a significant milestone in the country’s nuclear energy sector, reflecting advancements in technology and safety practices. The reactor will play a key role in addressing the growing demand for clean and sustainable energy, while simultaneously reducing the nation’s reliance on fossil fuels.

Remarks from NPCIL’s Chairman and Managing Director

NPCIL’s Chairman and Managing Director, B.S. Pathak, lauded the accomplishment, highlighting it as evidence of NPCIL’s proficiency in various aspects of nuclear power generation, encompassing design, construction, commissioning, and reactor operation. He further emphasized that this achievement underscores the organization’s commitment to adhering to the highest safety and performance standards. In addition, Mr. Pathak expressed confidence in NPCIL’s ability to contribute significantly to the nation’s clean energy goals, while providing reliable and efficient power to meet the growing demand.

Advanced safety features of the 700 MWe reactors

The locally built 700 MWe reactors feature cutting-edge safety measures, including steel lining extending from the floor to the wall and a passive decay heat removal system for cooling the fuel core. These state-of-the-art safety features ensure that any potential accidents are minimized, providing a secure environment for the operation of the reactors. Furthermore, the passive decay heat removal system offers an efficient and reliable solution for maintaining a stable temperature, reducing risks associated with overheating and ensuring the long-term viability of the nuclear reactors.

Top position among PHWR reactors

These attributes position them among the top reactors in the PHWR category. With their outstanding features and remarkable efficiency, these PHWR reactors hold great promise for the sustainable generation of nuclear power. Their advanced technology not only highlights the increasing innovation in the nuclear energy sector but also serves as a potential benchmark for future reactor designs.
