"On 1/20/15, it was determined that a certain line up of component cooling heat exchangers and shutdown cooling heat exchangers could exceed the design basis temperatures for the component cooling water system following a design basis accident. Although not a safety concern at this time because of low ultimate heat sink temperatures (which cools component cooling water), in the past the ultimate heat sink temperatures have been high enough to create this condition. This particular heat exchanger line up was unanalyzed in that the ultimate heat sink temperature limits were not known until 1/22/15. This issue has been entered into the corrective action program.
"A review of Control Room logs for 2014 showed that in 1 instance for Unit 1 and 1 instance for Unit 2, the Units were in an unanalyzed lineup with ultimate heat sink temperature greater than the maximum now calculated. During these instances, both Units had an unanalyzed condition that had potential to significantly degrade plant safety and is reportable in accordance with 10 CFR 50.72(b)(3)(ii)(B).
"The NRC Resident Inspector has been notified."
* * * RETRACTED ON 03/03/15 AT 1410 EST FROM CHARLES MORGAN TO JEFF HERRERA * * *
"Further engineering analysis has refined the ultimate heat sink temperature that provides an acceptable safety system response with the component cooling water and shutdown cooling heat exchanger lineups in question. The revised information demonstrates that the system lineups that occurred in the last 12 months did not result in an unanalyzed condition that significantly degrades plant safety. This event notification is retracted."
The NRC Resident Inspector will be notified.
The R1DO (Burritt) was notified.

"The retraction statement provided on 3/3/15 incorrectly addressed system lineups limited to the last 12 months. The original withdrawal was prematurely submitted and therefore the original notification (Event report 50752) is not retracted and remains valid.

On March 4, 2015, the licensee notified the State of Oregon that they discovered that their Elekta Leksell Gamma Knife was off target by approximately 1.87mm. This was allegedly due to maintenance performed in early January 2015, that resulted in a misaligned couch. Since the misalignment, eight patients have undergone gamma knife surgery. The licensee Medical Physicist is currently evaluating each case to determine whether an underdose/overdose occurred to any of the patients.
The Elekta Leksell Gamma Knife is licensed for up to 6.6 kCi of Co-60.
The State of Oregon will update this report as more information becomes available.
A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient. |

"On March 13, 2015, Watts Bar determined that information received from Westinghouse represented an unanalyzed condition. The information challenged the current Unit 1 Fire Protection Report (FPR) analysis for 10 CFR 50 Appendix R. The current FPR analysis used a duration of 120 seconds before a low pressurizer pressure safety injection (SI) signal would be received due to a postulated failed open pressurizer power operated relief valve (PORV) from an Appendix R fire outside of the control building. During discussions with Westinghouse, Watts Bar determined that the 120 second value was non-conservative and not intended for this application. Recent information from Westinghouse indicates that a Sl signal would be received in approximately 34 seconds.
"This information places Watts Bar Unit 1 in an unanalyzed condition because the original analysis assumed that a Sl signal would not be received from fire-induced failures in the associated fire areas. While the existing Watts Bar Unit 1 Appendix R procedures direct operators to isolate the pressurizer PORV, the procedures did not have steps to mitigate and terminate the Sl. Without mitigating actions, the Sl would likely challenge the reactor coolant system boundary due to water relief through the remaining pressurizer PORV and/or safety valves.
"As a compensatory measure, Watts Bar has established administrative equipment controls to preclude the consequences of a spuriously opening pressurizer PORV. In addition, a compensatory measure in the form of fire watches has been established in areas where a fire could result in a spurious opening of a pressurizer PORV.
"This issue is being reported under 10 CFR 50.72(b)(3)(ii)(B), 'unanalyzed condition that significantly degrades plant safety.'
"The Watts Bar Resident Inspector has been notified." |

| Event Text IMPROPER WELD USED ON GATE VALVE COVER
The following was received from the licensee via email:
"This notification is being submitted pursuant to the guidelines of 10 CFR Part 21 to report that, during the manufacturing of a replacement cover for a 24 inch gate valve on the reactor recirc line at Exelon LaSalle, Weir Valves and Controls used a weld that was not compliant to ASME Ill Subsection NB requirements.
"During review of the weld at site, the question was raised based on site procedures required a 2:1 profile in accordance to EPRI guidelines. During review of the documentation to determine if the 2:1 profile was required in this case, Weir Valves and Controls determined that improper weld call out was used on the design prints. The weld was corrected at site to meet the both ASME Ill Subsection NB requirements and EPRI guidelines.
"Weir Valves and Controls has performed an extent condition review and has concluded that no other undersized welds were made and delivered to any other operating sites.
"The root-cause of the issue was the improper call-out of the weld by design engineering.
"Weir Valves and Controls is performing corrective actions to ensure future re-occurrences cannot occur in design engineering." |
