    Abstract

    The boiling water simulator NOTAM has been modified and improved in several aspects:
    - The "1 1/2" energy group TRILUX nodal flux solution method has been exchanged with a 2 group nodal expansion method.
    - Control rod "history" has been introduced.
    - Precalculated instrument factors have been introduced.
    The paper describes these improvements, which were considered sufficiently large to justify a new name to the programme: COSIMA.
