In a recent development, the third unit of the Kakrapar Atomic Power Project (KAPP3) is now operating at full capacity. This achievement is a significant step towards India’s ambitious nuclear power goals.
Unveiling KAPP: Third Unit at Full Capacity
- The third unit of KAPP, known as KAPP3, has a capacity of 700 MWe (MegaWatt electrical).
The Significance of KAPP3
- KAPP3 is the largest variant of the Pressurized Heavy Water Reactor (PHWR) design.
- It surpasses the previous largest reactor, a 540 MWe PHWR in Tarapur, Maharashtra.
- KAPP3 is India’s first 700 MWe reactor, showcasing a significant technology scale-up.
- The PHWR design has been optimized for the 700 MWe unit, addressing excess thermal margins and benefiting from economies of scale.
Safety Features and Advantages
- PHWR technology boasts a high safety score.
- Notably, it employs thin-walled pressure tubes instead of large pressure vessels, mitigating the consequences of accidental ruptures.
Enhanced Safety Design
- The 700 MWe PHWR design incorporates a ‘Passive Decay Heat Removal System.’
- This system removes decay heat without operator intervention, akin to technology used in Generation III+ plants, aiming to prevent incidents similar to Fukushima.
Structural Safety Measures
- Steel-lined containment reduces leakages.
- A containment spray system reduces containment pressure during coolant loss scenarios. copyright©iasexpress.net
The Journey of KAPP: Financing and Execution
- The project is financed with a 70:30 debt-to-equity ratio.
- Equity partners include the Nuclear Power Corporation of India Ltd (NPCIL).
- The reactor building contract for KAPP Units 3 and 4 was awarded to Larsen & Toubro at a contract value of Rs 844 crore.
KAPP’s Timeline and Location
- KAPP-3 achieved its first criticality in July 2020.
- The first ‘pour of concrete’ for KAPP-3 took place in November 2010.
- KAPP is situated in the state of Gujarat, India.
India’s Nuclear Power Vision
Current and Target Capacity
- India’s current nuclear power capacity stands at 7,480 MWe.
- The country aims to achieve a capacity of 22,480 MWe by 2031.
Global Nuclear Contribution
- India’s current nuclear capacity contributes 2 percent to the global power generation capacity of 4,17,668 MW.
