the minimum value listed in the Technical Specifications.

f.

The following items, discussed in the report, are considered to

-6 be of special interest:

I' 1.

Three significant train wrecks have occurred recently in the g

vicinity of the Yankee plant on the routes that would have t

been used by the fuel shipment cask.

The cask was not in-volved in the accidents.

F i,

2.

A throttle valve to the main turbine failed to close com-pletely due to a buildup of chemicals on the valve stem -

boron and phosphate.

This situa tion may become a general problem for plants that have high concentratio ns of chemA als T

in their systems and operate for extended periods of time.

3.

Additional organizational changes are described in the report.

level at Yankee.
