Soviet physicist who linked fusion science, Chernobyl, and nuclear disarmament
Less than a month after absorbing radiation at Chernobyl, Velikhov chaired an international meeting on nuclear test-ban verification — turning disaster into a disarmament opening.
Soviet physicist who pioneered plasma physics for controlled fusion and MHD power. His 1959 thesis discovered magnetorotational instability, now foundational to astrophysics; in 1962 he identified electrothermal instability. He led the Soviet controlled-fusion program from 1973 and was Vice-President of the USSR Academy of Sciences (1978–1991), bridging the Kurchatov Institute and the Academy. During Chernobyl (1986) he served as Gorbachev's science advisor for reactor containment, then led science diplomacy for nuclear disarmament. After the Soviet collapse he sustained the Kurchatov Institute and became founding chairman of ITER, building the framework for joint US-Soviet-European-Japanese fusion research.

Science diplomacy and cooperative nuclear-test verification
Velikhov put his standing as a fusion physicist to work on nuclear arms control in the late Cold War. In the weeks after Reagan announced the Strategic Defense Initiative in 1983, he organized the Committee of Soviet Scientists for Peace and Against the Nuclear Threat (CSS) within the Soviet Academy of Sciences, with Roald Sagdeev as his deputy. The committee examined the technical limits of space-based missile defense and recommended that the Soviet Union not imitate SDI but adopt a far cheaper asymmetric strategy of countermeasures; it also sent an open letter to US scientists opposing moves to weaken the 1972 Anti-Ballistic Missile Treaty, opening reciprocal exchanges with the Federation of American Scientists.
At a May 1986 Moscow workshop he signed an agreement with the US Natural Resources Defense Council to establish jointly operated seismic stations around the Semipalatinsk test site in Kazakhstan, set up in July of that year; by 1988 Soviet seismologists were able to visit the Nevada Test Site. This collaboration built the technical basis for verifying a nuclear-test ban and opened a path toward the 1990s Comprehensive Nuclear-Test-Ban Treaty negotiations and the US-Russian agreement to end plutonium production for weapons. He also chaired the Soviet Scientists' Committee against nuclear war, mobilizing international scientific exchange, until 1988.
