DEFECTS AND NONCOMPLIANCE PART 21/50.55 REACTORS POTENTIALLY UNQUALIFIED COMPONENT IN CERTAIN ALLEN BRADLEY TIMING RELAYS The following is an excerpt from a document received from the licensee via email: "Report of potential 10 CFR Part 21, Allen Bradley Timing Relay Model 700RTC "Pursuant to 10 CFR 21.21 ( d)(3)(ii},

AZZ/N LI is providing written notification of the identification of a potential failure to comply. R1DO R2DO R3DO R4DO EMAIL "On the basis of our evaluation, it is determined that AZZ/NLI does not have sufficient information to determine if the subject condition would, or has, created a Substantial Safety Hazard or would have created a Technical Specification Safety Limit violation as it relates to the subject plant applications.

"The specific part which fails to comply or contains a defect: "As of 2009-2010, Allen Bradley relays base model 700RTC, contain an unevaluated CPLD (Complex Programmable Logic Device).

This was an unpublished design change that was implemented to replace an obsolete integrated circuit chip. The undocumented design change did not result in a part number change from Allen-Bradley.

There was no change to the appearance of the relay that would identify any design changes were made to the relay configuration.

Therefore, NLI qualification/dedication of the relays after 2009 have not included additional testing for the new CPLD component.

"The timing relay model 700RTC has been dedicated/qualified for multiple applications for various plants. "Between 2009-2010 Allen Bradley made a design change without changing the part number of the commercial 0512612016 U.S. Nuclear Regulatory Commission Operations Center Event Report Page 2 relay or providing any documented evidence of a design change. The manufacturer specification data sheets maintain the classification that the relays are 'solid state', which would imply that there are no digital devices installed in the relay. However, after inspection of the internals of the timing relay (Figure 2), it has been identified that the unit does contain a CPLD which meets the definition of a digital device under the guidance of NEI 01-01." Potentially affected plants include Browns Ferry, Ginna, Millstone, Nine Mile Point, North Anna, Ft.

it is determined that AZZINLI does not have sufficient information to determine if the subject condition would, or has, created a Substantial Safety Hazard or would have created a Technical Specification Safety Limit violation as it relates to the subject plant applications.

The following information is required per lOCFR 21.21 (d) (4). (i) Name and address of the individual or individuals informing the Commission.

NLI has *completed the EMC qualification I testing per the requirements of EPRI TR-102323 Rev. 4 for the following tests, as applicable:

CE 10 l, CE102, RElOl, llEI02, RSIOI, RS103, CS101, CS114, CSllS and CS116. The results were satisfactory with exception of the following condition:

During Conducted I Susceptibility CS 114 onto the power lines, with the timing circuit in operation, the instantaneous contacts exhibited chatter in the range of 2.6 MHz to 20.3 MHz. The unit requires a ferrite to be installed onto the input power lines of the relay with 3 turns through the fettite core. In this modified configuration, the relay was not susceptible to Conducted Susceptibility and successfully passed the required test per CSl 14. In addition to the EMC testing that was performed, the Verification and Validation I Dedication activities for the digital device was also completed, The results of the dedication activity are contained in NLI Verification and Validation/Dedication report VVR-700RTC-01, Rev. 1. The results of the V&V/dedication activity are satisfactory.

The firmware version verified is the only version that has been released since the change was implemented.

The functions of the relays supplied by NLI were tested for the foltowing critical characteristics:

The specific plant application(s) is unknown by NLI. The EMC qualification of the relay is dependent on the installed configuration and location in the plant. The plant should evaluate whether the installed relays are subjected to the specific EMIIRFI condition Conducted Susceptibility CS 114 between the :frequencies of 2.6 MHz to 20.3 MHz identified above.

The relays that are currently in stock at NLI have been placed on hold until after the units have been detennined to be qualified for the specific application.

NLI has *completed the EMC qualification I testing per the requirements of EPRI TR-102323 Rev. 4 for the following tests, as applicable:

CE 10 l, CE102, RElOl, llEI02, RSIOI, RS103, CS101, CS114, CSllS and CS116. The results were satisfactory with exception of the following condition:

During Conducted I Susceptibility CS 114 onto the power lines, with the timing circuit in operation, the instantaneous contacts exhibited chatter in the range of 2.6 MHz to 20.3 MHz. The unit requires a ferrite to be installed onto the input power lines of the relay with 3 turns through the fettite core. In this modified configuration, the relay was not susceptible to Conducted Susceptibility and successfully passed the required test per CSl 14. In addition to the EMC testing that was performed, the Verification and Validation I Dedication activities for the digital device was also completed, The results of the dedication activity are contained in NLI Verification and Validation/Dedication report VVR-700RTC-01, Rev. 1. The results of the V&V/dedication activity are satisfactory.

The firmware version verified is the only version that has been released since the change was implemented.

The functions of the relays supplied by NLI were tested for the foltowing critical characteristics:

Pick-up at rated voltage Drop-out when the voltage is removed Pick"up at degraded voltage Over-Voltage operation Insulation resistance Off delay settings are ac:ljustable from 2-120 seconds Fick-up voltage Drop-out voltage Dimensions and Configuration The relays are dedicated for generic application usage in timing applications.

The specific plant application(s) is unknown by NLI. The EMC qualification of the relay is dependent on the installed configuration and location in the plant. The plant should evaluate whether the installed relays are subjected to the specific EMIIRFI condition Conducted Susceptibility CS 114 between the :frequencies of 2.6 MHz to 20.3 MHz identified above. Please contact me with any questions or comments.
