Novovoronezh NPP-2 (ordered by OJSC VNIIAM)

R&D to develop the leak tightness detection system for fuel handling machines designed for VVR-440 and VVR-1000 reactors; the system is included in the scope of delivery of the fuel handling machine MPS-1200-UHL4 for units 1 and 2 of Novovoronezh NPP-2

The leak tightness detection system (LTDS) of fuel handling machines designed for VVR-440 and VVR-1000 reactors is designed for preliminary assessment of tightness of fuel elements during reloading operations without holding the elements in casing.

The LTDS implements a method for estimating the tightness of fuel elements based on the activity of Xe-133 released from a fuel bundle when it is removed from the core. During operation, fuel bundles are under high pressure of water in the reactor core; accumulating gaseous decay products create pressure inside fuel elements. If the fuel element if tight, gaseous decay products are hold inside it, only small quantities are released by diffusion through the walls. In non-tight elements the pressure of gaseous decay products is equal to the external pressure. When the fuel bundle is removed from the core, the external pressure drops and radioactive gases, most notably Xe-133, are released from fuel elements for a short time. Radioactive gases find their way into water; during bubbling of area close to fuel bundle surface gases are captured by air vented to the surface. By measuring the activity of gas in the air blow-off we can estimate the degree of tightness of fuel elements, taking into account the fuel burn-up and time elapsed after reactor shutdown.

Composition of LTDS:

  1. Aggregate-and-control unit
  2. Local / remote control panel.
The second LTDS was delivered to OJSC VNIIAM.
