Pursuant to 10CFR 21.21 (d) (3) (ii), AZZINLI is providing written notification of the identification of a potential failure to comply.
On the basis of our evaluation. 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 10CFR 21.21 (d) (4).
(i) Name and address of the individual or individuals informing the Commission.
Tracy Bolt, Director of Quality Assurance Nuclear Logistics, Inc 7410 Pebble Drive Ft. Worth, TX 76118 (ii) Identification of the facility, activity, or the basic component supplied for such facility or such activity within the United States which fails to comply or contains a defect.
The specific part which fails to comply or contains a defect:
As of2009-2010, 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 This was an unpublished design change that was implemented to replace an obsolete integrated circuit chip.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.
The timing relay model 700RTC has been dedicated/qualified for multiple applications for various plants.

NLI procured the commercial grade relays, dedicated, qualified and supplied the subject relays as Safety Related.
(iv)  Nature of defect or failure to comply and the safety hazard which is created or could be created by such defect or failure to comply.
Between 2009-2010, Allen Bradley made a design change without changing the part number of the commercial 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 ofNEI 01-01. See Figures l and 2 below:
Figure 1- Original qualified design (prior to 2009).
Relays supplied prior to 2009 are not affected by this issue.

(iv) Nature of defect or failure to comply and the safety hazard which is created or could be created by such defect or failure to comply. Between 2009-2010, Allen Bradley made a design change without changing the part number of the commercial 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 ofNEI 01-01. See Figures l and 2 below:

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.

Relays that have been procured and dedicated from 2009 to present are identified below.
(iv) Nature of defect or failure to comply and the safety hazard which is created or could be created by such defect or failure to comply. Between 2009-2010, Allen Bradley made a design change without changing the part number of the commercial 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 ofNEI 01-01.

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.

Subject:

Update- Report ofpotential 10CFR Part 21, Allen Bradley Timing Relay Model 700RTC - NRC Event Number 51030, Accession Number MLl S134AO 16 Revision 2, corrections:

1. Page 5 (vii), znd paragraph: changed EPRI TR-102323 Rev. 3 to Rev. 4.
2. Page 5 (vii), 3rd paragraph: changed 'timing~ contacts to 'instantaneous' contacts.

Pursuant to 10CFR 21.21 (d) (3) (ii), AZZINLI is providing written notification of the identification of a potential failure to comply.

On the basis of our evaluation. 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 10CFR 21.21 (d) (4).

(i) Name and address of the individual or individuals informing the Commission.

Tracy Bolt, Director of Quality Assurance Nuclear Logistics, Inc 7410 Pebble Drive Ft. Worth, TX 76118 (ii) Identification of the facility, activity, or the basic component supplied for such facility or such activity within the United States which fails to comply or contains a defect.

The specific part which fails to comply or contains a defect:

As of2009-2010, 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.

The timing relay model 700RTC has been dedicated/qualified for multiple applications for various plants.

05/26/2016 08:51 P.003/007 (iii) Identification of the firm constructing or supplying the baste component which fails to comply or contains a defect.

NLI procured the commercial grade relays, dedicated, qualified and supplied the subject relays as Safety Related.

(iv) Nature of defect or failure to comply and the safety hazard which is created or could be created by such defect or failure to comply.

Between 2009-2010, Allen Bradley made a design change without changing the part number of the commercial 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 ofNEI 01-01. See Figures l and 2 below:

Figure 1- Original qualified design (prior to 2009).

Relays supplied prior to 2009 are not affected by this issue.

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 testing per the requirements of EPRI TR-102323 Rev. 4 for the following tests, as applicable: CE 10 l, I

CE102, RElOl, llEI02, RSIOI, RS103, CS101, CS114, CSllS and CS116.

The results were satisfactory with exception of the following condition: During Conducted Susceptibility CS 114 onto the power lines, with the timing circuit in operation, the instantaneous I

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.

05/26/2016 08:51 P.003/007 (iii) Identification of the firm constructing or supplying the baste component which fails to comply or contains a defect.

NLI procured the commercial grade relays, dedicated, qualified and supplied the subject relays as Safety Related.

(iv) Nature of defect or failure to comply and the safety hazard which is created or could be created by such defect or failure to comply.

Between 2009-2010, Allen Bradley made a design change without changing the part number of the commercial 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 ofNEI 01-01. See Figures l and 2 below:
