that ball joints in the discharge piping are required.
A letter, SBU-62553, has been sent to YAEC for approval to procure these ball joints. The delivery is five (5) months for the ball joints.
Pipe supports for the new block valves are scheduled to be on site 2/1/83.
The blocking valves are on order by k'estinghouse now and are sched-oled for delivery in April 1983.
The delivery of the blocking valves might be improved by having the valve shipped ahead of the valve operator.
Expediting efforts are continuing.

Engineering schedule UE6C The integrated engineering and for Unit I contains construction schedule for Unit 1 negative paths.
indicates a number of negative paths, some of which have engi-neering constraints. Most of these are caused by incomplete engineering of pipe supports and unreleased for fabrication pipe spools, valves and pipe supperts.
j The status of these components continues to be reviewed on an item by item basis and every means possible will be used to meet and/or improve their fore-cast delivery dates.
