I. Engineering changes: New and improved systems and hardware

In the wake of the TMI. accident, the popular press has focused on the need for better operating procedures, better-trained operators, and improved management attitudes, but major changes are also being made in the equipment and systems of nuclear plants. The Nuclear Regulatory Commission´s TMI. Action Plan (NUREG-0660 and 0737) details these new requirements and lists numerous engineering fixes to be made. These, as well as nontechnical items in the plan, arise principally from recommendations in the reports of three groups ¿ the President´s Commission on the Accident at Three Mile Island, the NRC-sponsored Special Inquiry Group, and the NRC´s own Lessons Learned Task Force.
