Procedures and Procedure Changes Training materials based on changes in existing procedures made as a result of TMI 2 are being developed for training of personnel. These materials will address the areas of concern such as loss of main feedwater, auxiliary feedwater operation, loss of reactor coolant system flow, loss of reactor coolant, natural circulation, etc.

In the case of loss of reactor coolant, the changes include.new instructions for actions relating to small and medium size break LOCAs.
