TopWorx Information Notice: TIN 2016-01
13 June 2016
Subject: C7 Switches
Equipment Affected By This Information Notice: (4) C7-14521-E25 shipped on 6 August 2014
Purpose: The purpose on this TopWorx Information Notice (TIN) is to alert Fisher that, as of 27 May 2016, TopWorx was made aware of a situation which may affect the performance of the aforementioned equipment. TopWorx is informing Fisher of this circumstance in accordance with Section 21.21 (b) and 50.55 (e) of 10 CFR 21.
Applicability: This notice applies only to (4) TopWorx C7-14521-E25 shipped on 6 August 2014 to Fisher on Fisher Purchase Order 4123318082.
Discussion: Fisher Purchase Order 4123318082 specified that TopWorx SV7-14521-E25 were to be provided. Although the C7 switches provided to Fisher in error are also Nuclear-qualified switches, they do not have the same qualification pedigree and therefore cannot be considered qualified for HELB [High Energy Line Break] applications (zones 5 and 10). TopWorx has no indication that the switches provided are defective, yet TopWorx is unable to determine the application or status of use and therefore submits this notice.
Extent of Condition: Fisher Purchase Orders were reviewed and no other order was found where an incorrect switch was provided.
Actions Required: If the units mentioned above are to be installed in a zone for which the C7 switch is not qualified, then the units must be replaced. In addition, TopWorx has initiated a Non Conformance Report (NCR 05192016-01) to prevent reoccurrence of this issue.
10 CFR 21 Implications: TopWorx requests that the recipient of this notice review it and take appropriate action in accordance with 10 CFR 21.
