RO INSPECTION REPORT NO. 50-29/72-02
YANKEE ATOMIC ELECTRIC COMPANY
YANKEE ROWE - PWR
The subject inspection report is forwarded for information. One item
of noncompliance was identified, and the item was addressed in our
documentation letter.
.
Inspection findings relating to the ECCS installation and testing were
previously forwarded to your office in our memo, dated May 5, 1972.
Regarding item No. b in the referenced memo, Yankee Management stated,
during subsequent telephone conversations, that a qualified inspector
or exa=iner will inspect the sections of the ECCS constructed in
accordance with ANSI B 31.7.
With respect to the other previously
identified noncompliance items relating to the ECCS (R0 Report 50-29/
72-01), the licensee had corrected or planned to correct these items.
We believe that the licensee has made improvements in his QA program;
however, we are scheduling a QA meeting in July, 1972.
,
Our inspector identified two matters which we believe may warrant
further consideration. The first involves the pressurizar pressure
sensing line (1/2-inch stainless steel tubing) that is connected to
a transmitter (ECCS initiating circuit) in the primary auxiliary
building. We believe this line (installed in 1968 under Proposed
Change 82) represents a design inadequacy in that the section outside
the vapor container (about 100') has no excess flow protection. The
excess flow protection is located at the transmitter. This line also
contains a manual isolation valve inside the vapor container, and 'the
valve is accessible during operation. We believe that excess flow
protection inside of contain=ent,as required in the design of current
generation plants, should be provided as a backfit item.

The second matter involves the performance of the ECCS during 3 loop
operation. The licensee's analyses and testing program apparently
ignored this cas,e.
In a subsequent telephone conversation Mr. Autio,
Plant Superintendent, stated that the plant would not a operated on
-
3 loops until the analyses were completed.
