"At 1602 [CDT], Engineering personnel notified the control room that during review of a pipe stress calculation it was identified that non-conservative or incorrect methodologies were used in the calculation. This calculation was for a modification to install four; 3 [inch] drain lines between the Essential Service Water (ESW) (safety) and the Service Water (SW) (non-safety) in 1991. A preliminary ME101 stress analysis performed, which corrects the above-identified discrepancies, indicates that the pipe stresses at the drain line weldolet connection exceed the ASME code of record allowable stresses by approximately 50%, when the revised Stress Intensification Factor (SIF) is applied. This modification affected both trains (A & B) ESW trains.
"The normal system alignment uses the SW water to supply the ESW, then during accident conditions the SW and ESW systems isolate from each other so that two redundant separate train isolation valves isolate the ESW system. These 3 [inch] drain lines are located in the section of piping that is isolated from the ESW and SW systems.
"At the time of notification 'A' ESW was isolated from SW and 'B' ESW was in normal system alignment. 'B' ESW was declared inoperable and action was taken to separate the SW and ESW and isolate the 3 [inch] drain valves. With this action complete the non-conforming components have been removed from service and OPERABILITY of the ESW has been restored.
"This condition is been reported per 10 CFR 50.72(b)(3)(ii)(B).
"The NRC Resident Inspector has been notified."

"Further engineering evaluation determined that the four drain lines [3-inch] between the Essential Service Water (ESW) (safety) and the Service Water (SW) (non-safety) were found to be within the allowable limits for operability and are acceptable. As a result, the condition has been determined to not be reportable per 10 CFR 50.72(b)(3)(ii)(B)."

"Affected equipment includes two 4160 volt safety buses, four 480 volt safety buses, four 120 volt AC safety trains, and four 125 volt DC safety trains.
"Following an accident Class 1E AC Unit SGK05B may not be able to perform is design safety function if a single failure causes a loss of redundant Class 1E AC unit SGK05A. This is due to continued latent heat input from A train Control Room Pressurization Fan which continues to operate. SGK05A and B provide room cooling for all safety related electrical busses.
"Action Taken: Established the following compensatory measure - During accident conditions with both trains of CRVIS [Control Room Ventilation Isolation System] actuated if at any time SGKO5A trips then following completion of immediate actions Control Room pressurization fan CGK04A will be secured to reduce latent heat removal requirements for SGK05B."
The licensee has notified the NRC Resident Inspector.

"[On August 11, 2012 at 1845 CDT, the licensee identified] this condition applies to SGK05A. Action taken: Established compensatory measures that during an accident condition with both trains of CRVIS actuated, if at any time SGK05A or SGK05B trips for any reason then, following completion of immediate actions, Control Room pressurization fan on the same train with the tripped A/C unit will be secured if the other pressurization fan is running."
The licensee notified the NRC Resident Inspector.

The following information was received from the State of Rhode Island via fax:
"Event Type: Medical event involving the administration of Yttrium-90 microspheres.
"Notification(s): On August 30, 2012, the RI Department of Health Office of Facilities Regulation, Radiation Control Program received a phone call from the facility's Radiation Safety Officer, with a follow-up e-mail the same day.
"Event Description: On 08/28/2012, two incorrect doses were prepared for a Y-90 microsphere treatment. Both doses were for the same patient (i.e., two different treatment sites). One dose was drawn at 28.7% less than prescribed and the other dose was drawn at 22.9% less than prescribed. The final administered doses were less than 40.3% and 27.2% prescribed, respectively.
"Cause of the event: Under investigation and unknown at this time.
"Actions: Adverse effects to the patient are not expected; a follow-up reactive inspection is planned.

The following information was received from the Commonwealth of Massachusetts via fax:
"[The licensee] called the Agency [Massachusetts Radiation Control] to report that [the licensee] received leak test results that were above 0.005 microCurie for their 'Shimadzu' [Manufacturer] Ni-63 gas chromatograph instruments, each containing approximately 10 milliCurie foil sources. [The licensee] reported that the leak test results were 0.0053 and 0.0069 microCurie. [The licensee] stated that wipe surveys for Ni-63 were taken of the lab areas where these instruments were used. [The licensee] did not yet have the LSC [liquid scintillation counter] results of the wipe surveys. [The licensee] also disassembled the electron capture detectors (ECD) from the GC [Gas Chromatograph] instruments and placed them inside a scaled poly bag to store the ECD's until [the licensee] can return the ECD's to 'Shimadzu'." |

| Event Text AGREEMENT STATE REPORT - FIXED NUCLEAR GAUGE FOUND WITH STUCK SHUTTER
The following information was received from the State of Illinois via email:
"On Tuesday afternoon, the Agency [Illinois Emergency Management Agency] received a call from the RSO for Flint Hills Resources Chemical Intermediates, LLC (IL-01337-01). He called to report a shutter failure of a fixed gauge which he cannot close. The device manufacturer, Ronan Engineering, has been contacted and arrangements are pending for repair of the device. The RSO has isolated the area, posted warning signs and instituted a lock out/tag out procedure for the manway entrance to the vessel in order to prevent exposures which might occur from someone attempting to perform work within the tank that the gauge is located. Area surveys performed show no variations above normal (i.e., less than 1 milliR/h at 1 foot) for when the shutter is open and the unit is in operation. The shutter had last been tested in March with no abnormalities noted. The gauge has not been subjected to any corrosives or solvents or other conditions which exceed the gauge's prototype test conditions.
"The RSO was reminded of the requirement to provide a written report within 30 days of the event and to contact the Agency when the manufacturer was able to perform the site visit to evaluate/repair the device. The Agency considers this matter open pending those additional actions."
The Ronan gauge is model X90-SA1, S/N M7389, contains 24.5 mCi Cs-137. |

| Event Text INTERIM 10 CFR PART 21 REPORT REGARDING EMBEDMENTS FOR AP1000 PROJECT VOGTLE UNITS 3 AND 4
"[This notification] provides an interim report in accordance with 10 CFR 21.21 pertaining to the identification of noncompliances and deviations associated with embedments being supplied as basic components for the Vogtle Units 3 and 4, nuclear project.
"The evaluation of reportability in accordance with 10 CFR Part 21 could not be completed within the 60 day evaluation period due to the number of components found with noncompliances and deviations. It is currently expected that the evaluation of these conditions will be completed by November 6, 2012.
"If you have any questions, please contact Mr. Geoffrey Grant, Vice President of Licensing, Regulatory Affairs and Compliance."
"Component Supplier: Cives Steel Company of 102 Airport Road; Thomasville, GA 31757
"During receipt inspection, QC inspectors found that some of the embedments received from Cives Steel Company had noncompliances and deviations, some of which warranted evaluation under 10 CFR Part 21. Examples of the types of deviations identified include unacceptable welds and weld repairs, missing Nelson studs, damaged Nelson studs, improper painting, incorrect dimensions, and illegible markings for identification. Approximately 211 embedments have been identified as having a noncompliance or deviation.
"It is currently expected that the reportability evaluation for 10 CFR Part 21 will be completed by November 6, 2012, due to the quantity of embedments identified and the time required to evaluate the effects from these noncompliances and deviations." | |
