Subject:
Additional Information Requested by USAEC on Pipe Breaks Outside Containment, NES BIA00'3, Rev. I
Dear Dick:
Enclosed is the subject Report, Rev. I which now Indicates the ?oca-tion of the two alternate core spray valves as outside containment.
An evaluation of potential pipe failures near the alternate core spray valves showed that the valves will be adequately protected from pipe whip by the restraints that are to be Installed on the main steam and 3
bypass lines. There are no potential break locations in high energy lines greater than 1-inch diameter in the valve area that can result in Jet Impingement on the valves.
Since the actuator motors are totally enclosed and non-ventilated, there will be no adverse environ-mental ef fects.
l l
The draf t submi ttal letter forwarded wi th our letter P-5101-38 (August l
2, 1974) does not require revision, and may be used to summarize the l
conclusions and recommendations of the report.
l Sincerely, AUTOMATION INDUSTRIES, INC.
