Key Points

  1. Enrichment Levels → Natural uranium has U-235 (~0.7%) usable isotope (rest mostly U-238) → enrichment increases U-235 → 3–5% (power) → 20% → 60% → 90% (bomb) → 0–60% hard, 60–90% fast
  2. Iran’s Material Position → ~500 kg at 60% → can reach 90% in ~2 weeks → ~25 kg enough for 1 bomb → material stage nearly achieved
  3. Weaponisation Gap → gas to metal conversion → core shaping → detonation system → needs precision; takes weeks to months
  4. Delivery Systems → Shahab-3 (~1000–1300 km, ~700–1000 kg payload), Sejjil (~2000 km, solid fuel) → range and payload adequate; integration uncertain
  5. Core Issue → miniaturisation of warhead + survival during re-entry + integration with missile → most complex and decisive barrier
About the UPSC Civil Services Examination (UPSC CSE)

The UPSC Civil Services Examination (CSE) is one of the most competitive and esteemed examinations in India, conducted by the Union Public Service Commission to recruit officers for services such as the Indian Administrative Service (IAS), Indian Police Service (IPS), Indian Foreign Service (IFS), and others. The exam comprises three stages — Prelims, Mains, and the Personality Test (Interview) — designed to test a candidate’s knowledge, aptitude, decision-making, and leadership skills.


How to Prepare Effectively for UPSC CSE

Cracking the UPSC CSE requires a deep understanding of the syllabus, consistent revision, structured answer writing, and smart test-taking strategies.
