PART 21 REPORT - CRACKING IN KCR-13 STANDBY BATTERY JARS

The following was received via facsimile:

"The purpose of this letter is to provide the NRC a report in general conformity to the requirements of 10CFR Part 21.21 (a)(2). On October 22, 2013, C&D Technologies, Inc. (C&D) was informed by Entergy Nuclear Northeast that a KCR-13 battery installed at the Indian Point Nuclear Energy Center had developed a small crack in the polycarbonate jar material. The jar is a safety related component with the primary function of containing electrolyte. C&D does not believe that significant quantity of electrolyte was lost through this crack, because there was a normal level of electrolyte in the battery. This unit has been replaced, and the unit was sent by Entergy to an outside lab, Lucius Pitkin (LPI) of New York, NY, for analysis. As C&D did not have access to the components of the allegedly defective battery, and a report has not yet been issued by Lucius Pitkin, C&D cannot perform a root cause technical evaluation and affirm whether there is any defect in the component or manufacturing process, or whether the reported condition may have been due to user abuse of product, improper maintenance or other negligence or error. No formal report from Entergy or LPI Is expected before the expiration of the 60 day limit from the date C&D was notified of the issue. Thus, C&D is submitting this interim report to the NRC and notifying C&D's customers that use C&D KCR-13 batteries of this interim report. [C&D is also] initiating an action plan to evaluate the reported potential defect and determine whether it could pose a substantial safety hazard for any U.S. licensee using such batteries.

"Concurrent actions underway to complete the evaluation: a) On receipt of the final report by LPI/Indian Point by C&D, C&D shall evaluate the findings and the causes for failure. Maximum time 14 days from receipt of the report. b) In conjunction with the licensees identified in section vi, C&D will recommend maintenance assessment of all KCR-13 batteries at these locations to determine their status, and specifically the presence of any evidence of potential defects via visual examination. For any cells exhibiting the presence of potential defect, C&D shall further recommend that they be returned for analysis. Estimated completion date of analysis is thirty (30) days from the receipt of the returned batteries."

KCR-13 batteries are used in Indian Point and Monticello Nuclear Plants.

"Subject: Updated Interim Report - Inability to Complete 10CFR Part 21 Evaluation regarding cracking in KCR-13 Standby Battery Jars

"As previously stated, C&D did not have access to the components of the allegedly defective battery, and a report has not yet been issued by Lucius Pitkin. C&D cannot perform a root cause technical evaluation and affirm whether there is any defect in the component or manufacturing process, or whether the reported condition may have been due to user abuse of product, improper maintenance or other negligence or error until a final report Is issued by Lucius Pitkin. Although several requests to both Indian Point and Lucius Pitkin have been made, a receipt date for the analysis results is still indeterminate."

The following report was received via fax:

"C&D has recently received and is evaluating the report from Lucius Pitkin and will perform a root cause technical evaluation and affirm whether there is any defect in the component or manufacturing process, or whether the reported condition may have been due to user abuse of product, improper maintenance or other negligence or error. The planned final evaluation should be completed by May 31, 2014 at which time it is anticipated that a final report will be issued."

Notified the R1DO (Lilliendahl), R3DO (Riemer), and Part 21 Group (via e-mail).


* * * UPDATE AT 1640 ON 7/18/2014 FROM CHRISTIAN RHEAULT TO DONALD NORWOOD * * *

The following is a synopsis of information received via facsimile:

The information provided in the C&D facsimile serves as C&D's final analysis of the issue.

Conclusion: While the images do show indications of environment stress cracking (ESC) and fatigue, the lack of chemical evidence of the actual agent makes it difficult to determine the source of the material. Polycarbonate (the container material) has known stress cracking agents for example esters, aliphatic hydrocarbons, aromatic hydrocarbons, halogenated hydrocarbons, ketones, etc. and the C&D Installation and Operation Manual clearly states that the only approved material for contact with the jar and cover (other than materials used in the construction of the battery) for cleaning purposes is water and sodium bicarbonate. If one of the previously mentioned materials came into contact with the jar, it could have caused the ESC that was observed.

The standing recommendation to system operators is to limit any chemical that can come into contact with the battery to only approved materials. In the event that an unapproved material contacts the battery, the unit should be cleaned and observed for any subsequent damage caused by the agent.

Notified R1DO (Cahill), R3DO (Pelke), and Part 21 Group (via e-mail).

AGREEMENT STATE REPORT - MEDICAL UNDERDOSE

The following information was received via fax:

"On July 9, the licensee's radiation safety officer called to report a potential medical event had occurred the previous afternoon. The Agency was advised that an interstitial treatment could not be completed involving a High Dose Rate afterloader (HDR) at the University of Illinois at Chicago. As a result of safety features built into the HDR's programming, the first fraction of a four fraction treatment of 300 rad was automatically terminated and the source returned to the safe/stored position after only 6 rad had been delivered when unexpected resistance was detected in the source wire as it moved to the second dwell position. Subsequent attempts to clear the path and reinitiate the treatment were unsuccessful. As a result, an underdose of 98% of the fraction occurred. The HDR unit was subsequently re-run through its quality assurance tests for positioning accuracy with no anomalies noted. The patient was notified of the event immediately.

"A week before, the patient had 3 catheters surgically placed near the pelvis and their location relative to the treatment site verified by CT scan with an additional scan just before treatment was initiated. After reviewing the scan the written directive was modified to call for 18 dwell positions in three channels for a duration of 101 seconds. Four fractions were going to be completed on successive days. The scan suggested the possibility of the catheters being moved as a result of distention of some internal organs. Although the 'dummy' wire successfully traversed the initial path, and the active wire reached the first treatment position, after the initial 2 seconds of programmed dwell time, the HDR unit detected an unexpected delay in the wire moving to the second dwell position, presumably due to constriction of the pathway, and automatically retracted the active wire to the safe store position. With the assistance of the manufacturer's off site technical advisor, the error code was cleared and attempts were made to reinitiate the treatment however, the 'dummy' wire could not traverse the path and the treatment abandoned.

"In this instance the device performed as designed and subsequent quality assurance tests confirmed the device was operating as expected. Although no effect on the patient is expected from the event, physicians are determining what course of treatment options are available at this time. The licensee was advised of the requirement to submit a written report of the event in accordance with the regulations. Pending additional developments and submission of the report, this matter remains open for now."

The HDR Afterloader has a 5 Ci Ir-192 source and was being used to treat a cancer in the pelvic area.

PART 21 REPORT - NOTIFICATION OF DEFECTS ON 2 INCH BONNETS

The following information was received from Velan Inc by facsimile:

"SUBJECT NOTIFICATION: 2 INCH BONNETS, VELAN PART NUMBER 6943-014

"On May 16, 2014 [Velan] received notification from Westinghouse Electric Co. (WES) that 2 bonnets supplied by Velan to WES in early 2013 for installation at Comanche Peak exhibited the following issues:
- The bonnets were intended to be exact replacements for the bonnets built to drawing E73-020 Rev E (OEM is Velan) except for material change to SA-182 FXM-19. Bonnets were visually inspected when received at site. No issues were noted; both bonnets appeared to be identical.
- In April 2013, Unit 1 bonnet was installed in valve 1-8109. No issues were noted with the installation. The new bonnet was put into service.
-In April 2014, Unit 2 installation was scheduled to begin. After the disassembly of the valve, the old and new bonnets were compared. It was noted that the backseat dimensions are different between the 2 bonnets. The increase in backseat diameter on the new bonnet would cause the stem to not backseat. The decision was made to re-install the old bonnet and send the new bonnet back to the OEM, Velan.

"On June 10, 2014 the bonnet, identified in the last bullet above, arrived at Velan Plant 2.

"The review by the [Velan] Evaluation Committee was finalized on July 17 and concluded that:
-Four similar bonnets were delivered to WES on three different occasions in 1988 and early 90's
-The stem head diameter is 01.312 [inches] so, when opening, the stem may pass through the stem bore of the bonnet and not seat on the backseat.
-On opening, if the limit switches on the actuator do not function, the stem may enter the packing chamber. The packing may be deformed and a leak may develop. Stem travel is limited by the disc contacting the bonnet and/or the end of the stem thread stopping on the actuator drive nut.
-If the actuator and packing flange nuts are removed, there is the potential for the stem to blow out of the valve.
-The packing chamber depth will result in more packing being installed in the valve. This may result in a higher packing friction load on the actuator when operating and reduce the actuator margin.
-The smaller packing chamber will not affect safety. A different diameter packing may be required. The gland bushing diameter (01.744 inches) is less than the packing chamber diameter and will work correctly.

"These bonnets were fabricated against ASME Sec. Ill for installation in Class 2 systems. Not knowing exactly the nature of the application we cannot determine if the [above identified] potential issues may pose a significant safety hazard and therefore we have informed WES by way of a similar letter."

ULTIMATE HEAT SINK TEMPERATURE EXCEEDED TECHNICAL SPECIFICATION LIMIT

"At 1454 EDT on 20 July 2014, Turkey Point Units 3 and 4 entered the Action for Technical Specification (TS) 3.7.4, Ultimate Heat Sink (UHS). The action was entered because UHS temperature exceeded the limit of 100 degrees F due to a natural event. This report is in accordance with 10CFR50.72(b)(3)(v)(B) because UHS capability to remove residual heat is impacted. At 1800 EDT the NRC verbally approved a natural event Notice of Enforcement Discretion (NOED) which allows the ultimate heat sink temperature to exceed 100 degrees F up to 103 degrees F. Unit power levels have been maintained at Unit 3 100% and Unit 4 95%.

SMALL KEOWEE HYDROELECTRIC STATION OIL DISCHARGED TO THE KEOWEE RIVER

"On 7/20/2014, at 1700 hours EDT, a spill of approximately five (5) gallons of Teresstic 68 lube oil was identified in the Keowee Hydroelectric Station (KHS) tailrace. Teresstic 68 oil is used at the station as an equipment lubricant. The KHS tailrace feeds into the Keowee River that leads into Lake Hartwell. The estimated area of the oil sheen is approximately 30x50 feet and a cleanup response is currently in progress. The cause of the spill was attributed to a faulty oil float switch in the KHS unwatering pump that allowed the oil to spill into the KHS tailrace (Keowee River).

"South Carolina Department of Health and Environmental Control (SCDHEC) and the National Response Center were notified of the spill on 7/20/2014 at approximately 2002 and 1953 hours [EDT] respectively.

"This event was determined to be reportable pursuant to 10CFR50.72(b)(2)(xi) due to the notifications to the SCDHEC and the National Response Center.

"The licensee notified the NRC Resident Inspector.

"Initial Safety Significance: The oil did not contain any plant produced radiological material and while contained, poses no safety risk with respect to the health and safety of the public.

"Corrective Action(s): The oil spill sheen is isolated to an approximate 30x50 foot area of the Keowee River. Because the KHS is currently not operating, the water spill area is stagnant, i.e., there is little or no movement of the water containing the oil sheen. The source of the leak has been contained and an investigation is underway to determine the actual cause of the spill. There was no impact on plant operations. The event was entered into the station's corrective action program."
