| Event Text PART 21 - INTERIM EVALUATION OF A DEVIATION - CONTACTOR FAILURE
The following was received via FAX:
On May 18, 2016, Nuclear Logistics INC. (NLI) determined that a contactor failure that occurred at the Shearon Harris plant had failed due to an auxiliary contact chatter present on the seal-in circuit for the coil voltage. The auxiliary contact chatter was caused by the loss of the shading
coils. NLI will be submitting a full report on the issue to the NRC within 60 days.
The contactor that failed was a Size 4 Eaton Freedom Series with a special coil for degraded voltage condition.
Reference Number: P21-05192016
NLI reported that the following plants have these types of contactor's:
Region 2: Oconee, Turkey Point, Shearon Harris and North Anna
Region 4: Columbia and Waterford

The following is excerpted from the licensee submission:
"The specific part which fails to comply or contains a defect: The Contactor that failed in service is a Size 4 Eaton Freedom Series with an AZZ/NLI special coil for meeting specific degraded voltage conditions.
"Extent of condition: Size 3, 4 and size 5 Eaton Freedom Series contactors or starters with an NLI special degraded voltage coil that have been supplied by AZZ/NLI since December 2010.
"NLI procured the commercial grade contactors and installed the special coil that was required to achieve the specific degraded voltage condition. The units were qualified, dedicated and supplied for safety related applications. The contactors were commercially procured from Eaton, the Original Equipment Manufacturer (OEM).
"For contactors/starters utilized in continuous duty applications. the OEM shading coils on the contactor core ... have the potential to become loose and fall off. If the shading coils are not in the intended location on the core, there is the potential for excessive chatter to occur on the normally open auxiliary contacts that are closed when the contactor is energized.
"The safety function of the contactor is to reliably supply uninterrupted power (no contact chatter) to a load on demand. For special degraded voltage applications, the NLI supplied contactor is equipped with an NLI special coil that replaces the OEM coil.
"When the contactor/starters that have the special coil installed are utilized in a continuous duty operation (continuously energized greater than 60 minutes) the special coil reaches a higher temperature than the original manufacturer's coil. The increased heat is potentially causing degradation of the acrylic resin that is utilized by the manufacturer to hold the OEM shading coils onto the OEM core. After the acrylic resin is no longer providing a secure hold on the shading coils, the shading coils can then become loose from the iron core.

"On Monday June 13, 2016, the licensee's radiation safety officer contacted the Agency [Illinois Emergency Management Agency] to advise that a seed localization procedure utilizing a radioactive source was not going to be completed as planned. An I-125 seed had been implanted on June 9, 2016 to mark an area of the breast for subsequent examination and surgical explantation on June 13, 2016. However, the patient experienced a stroke during the interim days and the planned surgery for explantation aborted. Given the patient's condition it was determined that the risk associated with surgery to the patient was greater than the risk associated with not performing the seed retrieval. Initial estimates of the effective whole body dose are 3.7 Rem and dose to the breast 73 Rad. No permanent functional damage to the organ/tissue is expected as a result of the inability to remove the source. If the patient's condition improves and the opportunity arises, the seed may still be explanted at a much later date."

This was reported from the State of Alabama via facsimile:
"On June 13, 2016, the Radiation Safety Officer for Nucor Steel in Decatur, Alabama notified the Alabama Office of Radiation Control in regards to a piece discovered in scrap metal received via railcar. The piece appears to be a retaining ring approximately the diameter of a dime. The piece is reading over 5,000 mRad/hr at contact using a Ludlum model 15 survey meter. The piece has been secured in a building within the site boundary and away from employees. The licensee is continuing to research where and when the piece arrived onsite. The [Alabama] Office of Radiation Control plans to meet with site personnel on June 16, 2016. As of today, [6/14/16] 1235 CDT, this incident remains open until further investigation can be completed."

"On June 16, 2016, [representatives from the Alabama] Office of Radiation Control visited the site to conduct measurements and spectrum analysis. The retaining ring read 13.5 mR/hr at contact, 3.6 mR/hr at one foot, and 0.5 mR/hr at three feet with a Fluke 451P #2644, calibrated 12/10/15. Spectrum analysis using a Thermo IdentiFINDER revealed the isotope to be Co-56. This was confirmed through the Joint Analysis Center Collaborative Information System.
"As of today [06/17/16], 1025 CDT, this incident remains open until disposal options have been completed."

| Event Text PART 21 - INSUFFICIENT VALVE CAGE HARDFACING
The following is excerpted from an email provided by the supplier:
"Items subject to this Fisher Information Notice (FIN) are confined to the equipment and orders referred to in Table 1 [see original submission]. Specifically, 'Equipment' refers to the eight inch sized hardfaced HPNS cages supplied per the order numbers listed in Table 1.
"The purpose of this FIN is to alert affected customers that, as of 29 April 2016, Fisher Controls International LLC ( Fisher) became aware of a situation which may affect the performance of the aforementioned Equipment, including its safety-related function.
"Fisher is informing affected customers of this circumstance in accordance with Section 21.21(b) of 10 CFR 21.
"The Equipment in question is subject to CoCr-A hardface overlay requirements. The CoCr-A overlay deposit thickness must be 0.060 inch minimum after machining. However, the cages supplied in fulfilment of the orders listed in Table 1 may have insufficient hardfacing depth on the inside bore diameter at the top of the cages (approximately 1.50 inches from top).
"This issue first came to Fisher's attention when a material grade inspection revealed insufficient cobalt. Subsequent PMI testing confirmed the upper section at the top of the cage fell short of expected CoCr-A. Two in-stock cages were sent to a third party accredited laboratory for macroetch examination and hardness survey. The results of this survey confirmed the top of the cages did not meet the minimum hardness requirement of 34 HRC and further confirmed the insufficiency is limited to the uppermost 1.50 inches of the inside bore diameter of the cages.
"The absence of hardfacing at the mating surface between cage and plug creates the potential for galling, which could prevent the valve from performing its intended safety function. Testing has been conducted to analyze the risk of galling. Typically, galling is observed in cycle tests well exceeding the 600 cycle recommended lifetime for the equipment. However, testing has proven galling to be an unpredictable phenomenon and could occur prior to the recommended lifetime of the equipment. There are no known field issues with the affected equipment.
"The problem of post-hardfacing material shrinkage is associated with the ratio of bore diameter to cage wall thickness. Large bore diameter thin-walled cages are at greater risk for material shrinkage. A third party accredited laboratory performed additional macroetch supplemental tests and evaluations on similar cages of varying bore sizes. It was determined that this issue is unique to the 8 inch sized HPNS cages.
"Fisher will provide the affected customers with a properly coated cages at Fisher's cost. In addition, a Corrective Action Request (CAR 1804) has been initiated by Fisher to prevent reoccurrence of this issue."
The US reactor sites affected by this issue include VC Summer and Vogtle. The foreign reactor sites include Sanmen and Haiyang.
