1 visit our Braidwood Station to share common nuclear power plant experiences.

The initial presentation provided the delegation with an overview of e
the Comenonwealth Edison service area and organisation as it relates to Braidwood Station.- It also included the current unit status and some of the Station milestones. ' The pace of the presentation was slow as a result of speaking through an interpreter, how.,ver everything appeared to go well.
L The delegation appeared to be very intent listeners but were very
'f actively taking in all the sights (security, therinography, mini-sub, i
etc.) that they could. They all appeared to be well versed on power-plants, very observant and probably understood more english than we-gave them credit Cor. The interpreter comumented that the minister and deputy seemed to like Braidwood Station and spent time conferring on the differences between Braidwood Station and the Soviet plants.
. i j
The individual intareuts varied somewhat but the central theme of questioning seemed
'.o focus on the safety systems and design 3
