Challenge 4: Nuclear Infrastructure

CHALLENGE 1:
MAPPING OF IRRADIATED INFRASTRUCTURE;

  • Mapping HVAC, stacks, structures etc.

CHALLENGE2:
HEALTH MONITORING OF COMPONENTS DURING LIFETIME

  • monitor thickness of / corrosion on walls / civil works parameters (dome walls cementation cracks/areas)
  • taking material samples ( limited to surface swab and corrosion material (ie if valve piston degraded)
  • monitor healthiness of component ( temp pressure, geometry over time (wall thickness ))
  • access to confined regions (pipe systems, vessels, etc.)
  • monitor/inspect pipes internally (cabling health , EMC, EMI etc)

CHALLENGE 3:
INSPECT / REPAIR OF NPP EQUIPMENT

  • taking samples of spent fuel (such as water in vicinity of fuel - not fuel samples per se)
  • taking samples of pools
  • inspection and plugging of steam generator pipes.
  • replacement of components

CHALLENGE 4:
CLEAN ROBUSTLY (PARTS OF) NUCLEAR INFRASTRUCTURE EQUIPMENT:

  • cleaning of long-term storage pools.
  • decontamination of LRW tanks

CHALLENGE 5:
WASTE DISPOSAL

During the decommissioning phase of a nuclear plant, a lot of irradiated components have to be dismantled or have to be reduced in size.

  • solid RW fragmentation
  • reduce size of components; ILW / HLW
  • reducing the amount of radioactive waste by putting & melting it in furnaces.
  • dismantling components
