General Science and Technology

Energy technologies and the nuclear fuel cycle

First systematic UPSC revision with school-level arithmetic and basic science vocabulary; no specialist science degree assumed.

Includes

• Assigned sections and concise recall notes
• Available mapped practice and analysis of mistakes
• One initial closed-book review

Separate time needed

• Specialist derivations and laboratory training
• Subsequent revision and full mock tests
• Continuing technology and mission updates
• Duplicated ecology, agriculture, health-administration or energy-policy study

Editorial planning estimate; not learner timing data

• NIOS Science and Technology: Sources of Energy ↗

  Sections 12.2.1–12.2.2 and 12.3.1–12.3.6, PDF pages 4–6 and 9–18; conversion mechanisms only

• NIOS Science and Technology: Sources of Energy ↗

  Section 12.2.3, PDF pages 6–9; fission, chain reaction and fusion explanation

• Thorium Fuel Cycle ↗

  Fertile Th-232 conversion to fissile U-233 and selected AHWR/AHWR-LEU design/fuel-cycle contrasts. The three-stage sequence is assigned separately to the dated DAE parliamentary reply. Do not infer operating status from proposed designs or universal superiority of U-233.

• Reprocessing and Nuclear Waste Management ↗

  Opening fuel-cycle explanation and waste-management sections

• Hydrogen Fuel Basics ↗

  Introduction, Thermal Processes and Electrolytic Processes; exclude historical production shares

• Fuel Cell Basics ↗

  How Fuel Cells Work and Polymer Electrolyte Membrane Fuel Cells

• Solar Integration: Solar Energy and Storage Basics ↗

  Introduction on variable solar production, What Is Energy Storage?, and Types of Energy Storage: pumped hydropower, electrochemical and thermal storage. Distinguish power from energy capacity and account for conversion losses. Exclude US peak-demand generalisations, technology deployment shares and current permitting/market claims.

• Basic Professional Training Course: Design of a Nuclear Reactor ↗

  Sections 1.1 selected moderator/coolant paragraphs (PDF pages 6–7), 1.8 (pages 14–15), 3.2 (pages 26–27), and Removal of residual heat from the core (page 46). Read thermal/fast distinction, heat-transfer roles, neutron balance and safety layers. Do not generalise the thermal-reactor introduction to every reactor, equate every fast reactor with a breeder, or assign dated fleet shares, SMR definitions and resource-duration forecasts.

• Overview of experimental facilities in support of Sodium-cooled Fast Reactors ↗

  Specific interest for sodium coolant, opening two paragraphs: heat transfer, boiling point/pressure and chemical reaction with air/water. Use engineering trade-offs, not the stronger claims of guaranteed superior reliability, lower costs or current fleet experience.

• PFBR attained first criticality on 6 April 2026 ↗

  Release dated 7 April 2026: first criticality on 6 April, design/development responsibility, U-Pu MOX and U-238 blanket, sodium cooling and prospective thorium role. The milestone is not evidence of commercial power generation. Do not teach MOX as exclusive to fast reactors or treat projected benefits as measured outcomes.

• Roadmap to Generate Power from Nuclear Energy ↗

  Opening paragraph of the 17 December 2015 parliamentary reply: PHWR natural uranium, recovered plutonium in fast breeders, and the prospective U-233/thorium stage. Exclude capacity forecasts, deadlines, inexhaustibility language and current-status inference. Use this contemporaneous strategy explanation with separate later milestone evidence.

• India’s contributions to ITER ↗

  Article dated 17 February 2025: cryostat caption, in-kind-delivery paragraph (cryostat, shielding, cooling/cryogenics, neutral beam and diagnostics), and training explanation. Assign documented contributions and skills development. Exclude the inconsistent Aditya elapsed-time sentence, national historical superlatives, current workforce counts and guaranteed commercial outcomes.

• ITER frequently asked questions ↗

  Questions on Q >= 10, burning plasma, why ITER does not produce electricity, plasma versus engineering breakeven, fuel availability/tritium breeding and the opening safety explanation on tritium and neutron activation. Use mechanisms and experiment goals. Exclude changing records, first-ever claims, schedules, projected prices, fuel-sufficiency forecasts, blanket zero-risk claims and universally applicable waste-lifetime claims.

• Harnessing Biotechnology to Accelerate Advanced Biofuels Production (2016) ↗

  12 April 2016, first two substantive paragraphs: cellulosic biomass, enzymes and microbial conversion. Exclude forecasts and funding totals.
