SUBJECT: Preliminary Evaluation per 10 CFR Part 21 Report of Condition
W-2 Switches with Texin Starwheels
A preliminary evaluation has been performed to determine if the condition
reported could create a substAntial safety hazard and is thereby
reportable under 10 CFR Part 21.
This results of this preliminary evaluation indicate that the subject
x is reportable. is not reportable.
The preliminary evaluation justifying this determination is attached.

Docket No. 50-247
Westinghouse Technical Bulletin No. NSD-TB-74-10, dated 9/9/74, as
revised on 9/30/74, reported that the starwheels, made of a material
called Texin, in certain types of W-2 switches have exhibited failures.
All plants with such switches installed, including IP-2, were instructed
to replace all Texin starwheels in the affected W-2 switches. However,
the Technical Bulletin noted that "all switches having more than three
stages" can be "positively identified as not affected by this Bulletin".
During the recent refueling outage at IP-2, it was discovered that
several safety-related W-2 switches, having more than three stages, did
indeed have the Texin starwheels. This was verified by chemical tests
and infrared spectroscopic studies at Catholic University.
The affected starwheels have been replaced prior to unit restart. In
addition, the discovery of the Texin starwheels in these W-2 switches has
been communicated to industry via the INPO Nuclear Network.
A written report on this condition will be prepared and submitted to NRC
as required by 10CFR21.21.

10 CFR PART 21 NOTIFICATION REGARDING W-2 SWITCHES WITH TEXIN
THE FOLLOWING TEXT IS A PORTION OF A FACSIMILE RECEIVED FROM THE
"WESTINGHOUSE TECHNICAL BULLETIN NO. NSD-TB-74-10, DATED 9/9/74, AS
REVISED ON 9/30/74, REPORTED THAT THE STARWHEELS, MADE OF A MATERIAL
CALLED TEXIN, IN CERTAIN TYPES OF W-2 SWITCHES HAVE EXHIBITED
ALL PLANTS WITH SUCH SWITCHES INSTALLED, INCLUDING [INDIAN POINT UNIT
WERE INSTRUCTED TO REPLACE ALL TEXIN STARWHEELS IN THE AFFECTED W-2
SWITCHES. HOWEVER, THE TECHNICAL BULLETIN NOTED THAT 'ALL SWITCHES
HAVING MORE THAN THREE STAGES' CAN BE 'POSITIVELY IDENTIFIED AS NOT
AFFECTED BY THIS BULLETIN.'"
"DURING THE RECENT REFUELING OUTAGE AT [INDIAN POINT UNIT 2], IT WAS
DISCOVERED THAT SEVERAL SAFETY-RELATED W-2 SWITCHES, HAVING MORE
THREE STAGES, DID INDEED HAVE THE TEXIN STARWHEELS. THIS WAS
THE CHEMICAL TESTS AND INFRARED SPECTROSCOPIC STUDIES AT CATHOLIC
"THE AFFECTED STARWHEELS [HAD] BEEN REPLACED PRIOR TO UNIT 2 RESTART.
ADDITION, THE DISCOVERY OF THE TEXIN STARWHEELS IN THESE W-2
BEEN COMMUNICATED TO INDUSTRY VIA THE INPO NUCLEAR NETWORK."
THE LICENSEE STATED THAT THIS ISSUE AFFECTED THE RECIRCULATION
FOR SAFETY INJECTION (RECIRCULATION MODE).
THE LICENSEE PLANS TO NOTIFY THE NRC RESIDENT INSPECTOR.
