Introduction
RWMR RWMR being used for registration
Complicated
For large number of sources
Need extensive training

19. Introduction Difficulties and challenges: Complete NSTS
Link between waste soft and SNRRA
Registry of orphan sources
RWMR is very Complicated
RWMR Need extensive training
Training to reduces human errors
