Products classified under HTS 8401.10.00.00
PWR Pressurized Water Nuclear Reactor
A Pressurized Water Reactor (PWR) is a nuclear reactor type where water acts as both coolant and moderator under high pressure to prevent boiling. It falls under HTS 8401.10.00.00 as it is a complete nuclear reactor designed for generating electricity in power plants.
BWR Boiling Water Nuclear Reactor
A Boiling Water Reactor (BWR) allows water to boil in the core, producing steam directly for turbines. Classified under HTS 8401.10.00.00 as a nuclear reactor for power generation.
CANDU Heavy Water Nuclear Reactor
CANDU reactors use heavy water as moderator and coolant, enabling use of natural uranium fuel. This complete nuclear reactor system is covered by HTS 8401.10.00.00.
VVER Russian Pressurized Water Reactor
VVER (Water-Water Energetic Reactor) is a Russian-designed PWR used in many Eastern European plants. It qualifies under HTS 8401.10.00.00 for complete nuclear reactor imports.
AP1000 Advanced Passive Nuclear Reactor
The AP1000 is a Generation III+ PWR with passive safety systems relying on natural forces. As a complete nuclear reactor, it is classified in HTS 8401.10.00.00.
RBMK Graphite Moderated Nuclear Reactor
RBMK is a Soviet-designed reactor using graphite moderator and light water coolant, known from Chernobyl. Falls under HTS 8401.10.00.00 as a nuclear reactor.
SMR Small Modular Nuclear Reactor
Small Modular Reactors (SMRs) are factory-built reactors under 300 MWe with integral designs. Classified as complete nuclear reactors under HTS 8401.10.00.00.
