Products classified under Tariff item 8401.40
Containment Penetration Sleeve
A containment penetration sleeve is a pressure-tight, seismic-qualified assembly that allows piping and cabling to pass through the reactor containment structure while maintaining the integrity of the containment barrier. It is an essential safety component of a nuclear reactor, as it ensures the containment remains leak-tight under normal and accident conditions. This sleeve is classified under tariff item 8401.40.00 as a part of nuclear reactors.
8401.40.00Control Rod Drive Mechanism Housing
A control rod drive mechanism housing is a pressure-tight enclosure that contains the mechanisms used to insert and withdraw control rods, thereby regulating the nuclear fission rate in a reactor. It is a critical component of the reactor's reactivity control system and is designed to withstand high pressures and temperatures. This housing is classified under tariff item 8401.40.00 as a part of nuclear reactors.
8401.40.00Core Support Barrel
A core support barrel is a cylindrical structure that positions the reactor core within the pressure vessel and directs coolant flow in pressurized water reactors (PWRs). It is a fundamental reactor internal that ensures proper core alignment and thermal-hydraulic performance. This barrel is classified under tariff item 8401.40.00 as a part of nuclear reactors.
8401.40.00Nuclear Fuel Assembly Flow Skirt
A nuclear fuel assembly flow skirt is a bottom flow distributor attached to fuel assemblies to ensure proper coolant distribution across the core. It is a reactor-specific component designed to optimize thermal-hydraulic performance and is supplied as a replacement part for nuclear reactors. This skirt is classified under tariff item 8401.40.00 as a part of nuclear reactors.
8401.40.00Nuclear Reactor Internals Upper Guide Structure
A nuclear reactor internals upper guide structure is a lattice framework installed above the reactor core to align and guide control rods and fuel assemblies during refueling operations. It is a critical reactor internal that ensures precise positioning and safe operation. This guide structure is classified under tariff item 8401.40.00 as a part of nuclear reactors.
8401.40.00Nuclear Reactor Pressure Vessel
A nuclear reactor pressure vessel is a massive cylindrical steel vessel designed to contain the reactor core, coolant, and heat generated during nuclear fission in a pressurized water reactor (PWR). It is a critical structural component that ensures the safe containment of the reactor. This vessel is classified under tariff item 8401.40.00 as a part of nuclear reactors.
8401.40.00Reactor Coolant Pump Casing
A reactor coolant pump casing is a high-pressure casing that houses the impeller of primary coolant circulation pumps in nuclear power plants. It is part of the reactor coolant pressure boundary and is essential for maintaining coolant flow. This casing is classified under tariff item 8401.40.00 as a part of nuclear reactors.
8401.40.00Reactor Core Shroud
A reactor core shroud is a stainless steel cylindrical assembly that surrounds the nuclear fuel assemblies in boiling water reactors (BWRs), directing coolant flow and providing radiation shielding. It is a reactor-specific component that ensures proper core cooling and safety. This shroud is classified under tariff item 8401.40.00 as a part of nuclear reactors.
