Containment-Liner

Containment-Liner show reference
BE_CL_01

Containment liners are steel liners installed at the inside of the concrete reactor containment buildung to ensure the required tightness of the reactor building for all operation modes and conditions. Made of thin metal sheets (approx. 6 mm), liners are embedded by means of bolts and other fixtures during the concrete casting work for the reactor containment building and serve as formwork at the same time. Depending on the relevant concept for casting, different alternatives for construction, e. g. solutions using individual sheets or rings, will be applied.
 
Scope of supply and services:

Detailed engineering and calculation, material sourcing, pre-fabrication, transport, pre-assembly on-site, final assembly, all construction and quality checks as well as final documentation

Containment Vessel

Containment Vessel show reference
BE_SH_01

The containment vessel contains all of the nuclear equipment and components used in a nuclear power plant. In most cases, it is a spherical shell made of high-strength steel and has numerous gas-tight ports and penetrations. It represents the inner containment of state-of-the-art power plants.
During plant operation, a slight negative pressure inside the containment prevents radioactive substances from leaking into the environment. The containment vessel is designed to withstand excess pressure loads and elevated temperatures in case of incidents.

Material and Air Locks

Material and Air Locks show reference
BE_AL_05

Airlocks are pressure vessels with two airtight doors penetrating the containment to permit access to the reactor building and to maintain sealing off from the outside atmosphere.
Airlocks permit controlled transfer of personnel and/or material into and from the
containment and thus ensure that the operating conditions inside the containment are maintained. The airlock is designed to prevent uncontrolled pressure loss in and contamination leakage from the reactor building.
Depending on customer requirements, various systems of lock opening mechanisms are available.

Airlock functions

  • Personnel access to the containment.
  • Emergency egress and rescue from the containment.
  • Prevention of uncontrolled access to the containment.
  • Prevention of uncontrolled contamination leaks
  • Material transfer into and out of the containment
  • Integrity in case of design-basis incidents

Technical Data:

  • Weight: approx. 28 t
  • Length: approx. 7,5 m
  • Diameter: 3,1 m
  • Design pressure (abs): 5,3 bar
  • Design temperature: 170 °C
  • Design sub pressure: -40 mbar

BE_K_KGS_01

Babcock Noell supplies special compact storage racks for storing spent fuel rods space efficiently.

These compact storage racks provide an increased storage density of fuel rods all the while preventing critical arrangement by placing borated stainless steel or boron carbide between the rods to absorb neutrons (protons).

Besides compact storage racks, which are located in the fuel pool during operation, Babcock Noell has also developed mobile storage racks used for refueling which requires a sufficient number of storage positions for a complete core discharge.

In nuclear technology, safety is the highest priority. Among other products, Babcock Noell supplies mechanical components for the stabilization system for a hypothetical core meltdown (Components of Core Melt Stabilization System).

Located underneath the reactor, the melt plug is fastened to a wall installation frame by locking bolts. For maintenance purposes, the melt plug is unlatched by a remote-controlled transport system and transferred through a channel to its park position on a transport cart. The system also features neutron shielding on tracks.

Scope of supply and services:

Detailed engineering and calculation, material sourcing, pre-fabrication, transport, pre-assembly on-site, final assembly, all construction and quality checks as well as final documentation

BE_RK_01

Babcock Noell supplies handling systems required during reactor operation such as e. g. the handling system of the reactor pressure vessel closure head. The RPV Closure Head Equipment is a two-tier support and transport system.
 
During reactor operation, the lower part, the accessible support system, is mounted on the RPV closure head and is used for supplying power to the control rod drives and to diverse measuring systems. In the case of a maintenance inspection, the transport cross head is mounted and connected to the support system to lift and transport the RPV closure head.
 
The component is designed and dimensioned such that the special load case of an earthquake can safely be managed.

Scope of supply and services:

Detailed engineering and calculation, material sourcing, pre-fabrication, transport, pre-assembly on-site, final assembly, all construction and quality checks as well as final documentation

Filter Changing Machines

Filter Changing Machines show reference
BE_FCM_01

The pool water treatment systems in nuclear power plants are equipped with special filters which need to be replaced once certain radiation limit values have been reached. For protection against radiation, a remotely controlled shielded filter replacement apparatus is used for replacing filters.

The filter replacement unit is positioned with a new filter above the filter recess, opens the filter housing, removes the spent filter cartridges, and replaces the new filter cartridges. In its end position, the filter replacement unit places the spent fuel cartridges in a drum shield for further transport to the waste treatment plant.
