SUBJECT:

CORRECTION TO

REPORT

NO. 50-251/87-16

A calculational

error

has

been

found in paragraph

13

(page 35) of the

subject report.

Under the discussion of the effects of changes

in axial offset

on reactor coolant inventory calculations,

the change for a

5X offset change

should

be 3.3 gallons

and not 50 as stated.

The error resulted

from the use of

the entire reactor coolant

system

volume

(8043 cubic feet) in the calculation,

instead of the core volume (536 cubic feet).

This error does

not affect any of

the findings of the report.

We regret

any inconvenience it may have

caused

you.

Sincerely,
