Norwich Business School 32 FUEL TYPE - enriched URANIUM OXIDE - 2.3% clad in stainless steel MODERATOR - GRAPHITE COOLANT - CARBON DIOXIDE SUPERHEATED
{"Image DocumentName": "CANDU REACTOTS (PHWR)FUEL TYPE - unenriched URANIUM OXIDE clad in Zircaloy. MODERATOR - HEAVY WATER COOLANT - HEAVY WATER.", "Image ImageDescription": "ADVANTAGES:- MODEST POWER DENSITY - 11 MW/m3. HEAVY WATER COOLANT - low neutron absorber hence no need for enrichment. ON LOAD REFUELLING - and very efficient indeed permits high load factors. MINIMAL CONTAMINATION from burst fuel can - defective units can be removed without shutting down reactor. MODULAR: - can be made to almost any size. DISADVANTAGES:- POOR LOAD FOLLOWING CHARACTERISTICS. CONTROL RODS ARE HORIZONTAL, and cannot operate by gravity in fault conditions. MAXIMUM EFFICIENCY about 28% OTHER FACTORS:- MODERATE FUEL BURN-UP - ~ MODEST FUEL BURN-UP - about 1000TJ/tonne. FACILITIES PROVIDED TO DUMP HEAVY WATER MODERATOR from reactor in fault conditions. MULTIPLE PRESSURE TUBES instead of one pressure vessel. 33.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
