training and a written examination on the transient. Additionally, these' y33 operators attended training sessions on the: Babcock and Wilcox simulator tod ;

All training was completed ~ before operators could resume their duties duringie "t':

We recognize the importance of making complete and accurate information avail-l able to the public. Consequently, we have made specific plans for providing information' to the public for such potentially serious accidents as occurred i

at Three Mile Island. These plans include making the availability of public i
