# [TECH] Nuclear Power Generation

**Nuclear Power** generates electricity from controlled fission chain reactions in nuclear reactors, providing ~10% of global electricity with no CO₂ emissions during operation.

## Overview

Enrico Fermi's Chicago Pile-1 (1942) achieved the first controlled chain reaction. The first commercial nuclear power plant opened at Obninsk (USSR, 1954) and Calder Hall (UK, 1956). Light water reactors (pressurised water and boiling water) became the dominant design. By 2023, ~440 reactors operate worldwide generating ~2,600 TWh/year. Nuclear power provides baseload electricity with no carbon emissions but faces challenges from accident risk (Chernobyl 1986, Fukushima 2011), waste storage, and high capital cost.

## Key Actors

- **Companies**: Westinghouse Electric (US), General Electric (US), EDF (France), Rosatom (Russia), KEPCO (South Korea)
- **Inventors**: Enrico Fermi (1901–1954), Walter Zinn, Alvin Weinberg

## Key Patents

- Fermi, E. & Szilard, L. US Patent 2,708,656 (1955) — nuclear reactor (filed 1944)

## Economic Value

Global nuclear power market: **\$USD 400 billion/year** (World Nuclear Association 2023). Provides ~2,600 TWh/year of low-carbon electricity. With the global carbon price at \$USD 50/tonne, the carbon-free value of nuclear is an additional ~\$USD 130B/year.

## Notes

WNA *Nuclear Power Economics* 2023. Nuclear power avoids ~2.5 Gt CO₂/year globally. OECD NEA estimates the full lifecycle social value including carbon avoidance at \$USD 600B+/year.

## What This Enables

- **[TECH] Electric Vehicles (EVs)** — Nuclear provides dispatchable, low-carbon baseload electricity that charges EV fleets at night.
- **[TECH] Quantum Computing Hardware** — Quantum computers require extremely stable, uninterrupted power; nuclear baseload supportsThis is a current frontier node — no downstream connections yet recorded in this better than intermittent renewablesgraph.
