 MP98, an innovative company, develops a new nuclear reactor control system.
 This system needs control of neutron flux density (energy) and its distribution.

MP98 has selected best SPND producer for it's own needs. Therefore MP98 is exclusive representative for these SELF-POWERED NEUTRON DETECTORS (SPND) and associated systems.

Self-powered neutron detectors (SPND) are the most widely applied 
detectors nowadays.


Design SPND
  • SPND is a source of current, in which the current to be measured is generated due to kinetic energy of charged particles.

SPND ADVANTAGES :
The most reliable and industrial solution to obtain permanently flux map in a nuclear reactor (Total operating time: SPND - not less than 350000 reactor years).
The best system to perform fuel burn up and save margin.
The safer system under earthquake and for long term control after accident.

  • Miniature, diameter sensitive part of 1,4-1,5 mm
  • Smaller enough to be adapted to any kind of reactor and size;
  • Operate inside the reactor core;
  • Does not require feeding;

  • Neutron does not require calibration during manufacturing process; supplied detectors are not induced radioactivity;

  • Linearity on the measured parameters;

  • Virtually unlimited upper limit of measurement;

  • Low sensitivity to gamma-ray background reactor;

  • Operating temperatures up to 650°C. There is experience in the use at higher temperatures;

  • and others...
