### Operational Licensing of Home-built 700 MWe PHWRs: Strategic Leverage in India's Nuclear Energy Framework The granting of operational licenses by the Atomic Energy Regulatory Board (AERB) to two 700 MWe Pressurised Heavy Water Reactors (PHWRs) at Kakrapar Atomic Power Station (KAPS) symbolizes a critical intersection in India's nuclear energy policy. This marks a key milestone within the broader context of India’s three-stage nuclear programme, conceived to advance energy security by leveraging indigenous technology. The intrinsic tension here lies between **energy self-reliance through indigenization** and reliance on imported reactor technologies to meet immediate energy demands. --- ### UPSC Relevance Snapshot - **GS-III:** Science and Technology - Nuclear energy development and applications - **Subtopics:** Indigenization of technology, energy security, three-stage nuclear programme - **Essay Potential:** "Is Nuclear Energy the Answer to India's Energy and Environmental Dilemmas?" --- ### Arguments FOR the Indigenous 700 MWe PHWRs India's successful design, construction, and operation of 700 MWe PHWRs underscores technological maturity and energy autonomy as envisioned in the **AatmaNirbhar Bharat Abhiyan**. - **Technological Indigenization** - Evolution of the 700 MWe PHWR design from earlier 540 MWe model demonstrates domestic R&D capabilities rooted in the **three-stage nuclear programme.** - Heavy reliance on local materials, components, and expertise reduces the geopolitical risk tied to global nuclear supply chains. - **Energy Security and Supply Stability** - Indigenous PHWRs reduce dependence on imported Light Water Reactors (LWRs) and fossil fuels. As per current government estimates, nuclear power will contribute **22,480 MW by 2031-32.** - Utilization of natural uranium as fuel and heavy water as a moderator boosts fuel efficiency in contrast to LWRs. - **Environmental Advantages** - Nuclear power generates near zero Greenhouse Gas (GHG) emissions. With India's **Paris Agreement NDCs** requiring emission intensity reduction by 33-35% (2005 baseline), this aligns with sustainable targets. - **Cost Competitiveness** - Indigenized reactors mitigate high costs associated with imported technologies, ensuring lower tariffs alongside reducing import dependency. --- ### Extractable Knowledge: Notable Facts Supporting Indigenous Reactors - **Historical Context:** India’s nuclear journey began with Asia's first research reactor, **Apsara (1956)**, and the nuclear power plant at Tarapur (1969). - **Operational Milestones of KAPS Reactors:** - KAPS-3 full commissioning: August 2023 - KAPS-4 full commissioning: August 2024 --- ### Arguments AGAINST: Challenges and Limitations Despite its merits, the operationalization of indigenous reactors faces critical economic, technical, and governance hurdles, which highlight systemic weaknesses in India’s nuclear framework. - **Regulatory and Safety Concerns** - Incidents involving radiation leakage in older reactors emphasize the need for robust safety protocols. The **CAG report (2021)** flagged inadequate disaster preparedness in some nuclear plants. - **Production and Infrastructure Constraints** - Current uranium production (~1% of global output as per IAEA) barely suffices for existing reactors, highlighting **resource bottlenecks.** While new deposits have been discovered at Jaduguda, exploration remains constrained. - Integrated back-end facilities like fuel reprocessing plants are under-developed, limiting a complete closed fuel cycle. - **High Initial Capital Costs** - PHWRs require significant upfront investment compared to renewables. **Economic Survey 2023** recognized that the per MW installation cost for nuclear energy is much higher than solar or wind alternatives. - **Prolonged Project Delays** - Projects like the **Prototype Fast Breeder Reactor (PFBR)** at Kalpakkam have seen repeated delays, illustrating inefficiencies in execution. --- ### Comparative Table: India's Nuclear Energy vs France’s Nuclear Dominance
| Parameter | India | France |
| Nuclear Share in Total Energy Mix | ~3% (as of 2023) | ~70% |
| Number of Reactors | 22 operational; ambition for 30+ | 56 operational |
| Reactor Technology | Predominantly PHWRs, some LWRs | LWRs (dominance of PWRs) |
| Nuclear R&D Investment | Rising under "Atmanirbhar Bharat" | High; focus on advanced systems |
| Cost of Production | Higher than renewables | Competitive due to scale |
--- ### Latest Developments: The Edge of 2025 - **Jaduguda Uranium Expansion**: Discovery of substantial reserves, extending operational capacity of India’s oldest mine by 50 years. - **ASHVINI Collaboration**: Joint venture between **NPCIL and NTPC** to boost capacity. Upcoming project: 4×700 MWe PHWRs at Mahi-Banswara, Rajasthan. - **PFBR Advances**: Key milestones achieved in the Prototype Fast Breeder Reactor, with core loading initiated in March 2024. --- ### Structured Assessment: Multi-Dimensional Evaluation 1. **Policy Design** - Clear alignment with national energy targets (22,480 MW by 2031-32). - Synergy with international commitments (Paris NDC). 2. **Governance Capacity** - Strengthened institutional frameworks (e.g., AERB supervision). - Persistent timeline overruns weaken reliability. 3. **Behavioral/Structural Factors** - Public opposition due to perceived safety risks. - Low awareness regarding nuclear as clean energy compared to solar/wind systems. --- ### Exam Integration #### Prelims MCQs 1.
