AECS Research Reactor (RR) Types Miniature neutron source reactor - - PowerPoint PPT Presentation

AECS

Research Reactor (RR) Types

• Miniature neutron source reactor (MNSR) of 30kW

to about 100MW(t) RR (1–10 MW more common)

• Industrial manufacturer supplied RR to custom­built

indigenous RR

• Neutron flux ranging from 10

11 to 10 14

– Neutron beam facilities – Sample irradiation facilities (radioisotope production, material testing) – Rabbit facility for NAA – Analytical and other services facilities

AECS

Research Reactor issues and needs

• Need exists for beneficial utilization to be the basis for
• peration & utilization of RR in safe and secure manner.
• RR as the symbol of nuclear science and technology
• RR as the cradle of all development and availability of nuclear

technology

• RR utilisation needs and requirements for safety & security

upgrades vis­à­vis resources availability and national support/ priorities/ policies

• RR fuel issues – conversion of HEU fuel to LEU fuel;

development & qualification of high density LEU fuels
