| Event Text AGREEMENT STATE REPORT - DELIVERED DOSE IS DIFFERENT FROM THE PRESCRIBED DOSE
The following information was received by facsimile:
"On September 14, 2010, the Department [Wisconsin Department of Health Services] received a facsimile from the licensee's Radiation Safety Officer (RSO) that a medical event occurred on September 9, 2010, involving a permanent implant of I-125 seeds for a prostate manual brachytherapy procedure where the total dose delivered differs from the prescribed dose by 20% or more. This is a medical event as described in DHS 157.72(1)(a)1. The prescribed dose was 145 Gy; the dose delivered was 80 Gy. The licensee uses D80 < 80% as their dose based criteria for determining medical events. Using the licensee's dose based criteria of D80 < 80% the dose received by the prostate was 55% of the intended dose. The underdose was identified during the post-implant planning for the procedure. The RSO indicated that the possible cause was the maximum insertion depth was 0.6 cm below the base of the prostate gland and all needles were implanted distal to the base resulting in the area being 'cold'. Possible corrective actions are under review by the licensee's staff and a one month post-implant CT is planned to determine the impact to the patient.
"[Department] inspectors will investigate this medical event on September 16, 2010."

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. |

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text AGREEMENT STATE REPORT - MISSING GERMANIUM-68 CHECK SOURCE
The following report was obtained from the State of Maryland via e-mail:
"As follow-up to a telephone discussion [on the] afternoon of Sept. 14, 2010 at 1445, [the RSO sent the State of Maryland] this email as a written notification of a presumed lost sealed source containing radioactive material. The telephone notification and this email serve [as] compliance with Section D.1201a, which requires an immediate report of a theft or loss of a source of radiation.
"The sealed source in question contains Germanium-68, a nuclide of half-life 271 days. This nuclide decays to Gallium-68, which itself then decays (with positron emission) with a half-life of 68 minutes to stable Zinc-68. The annihilation radiation from the positron emission is used for PET scanner quality assurance, as in the case of this source.
"This sealed source originally contained 500 microCi of Ge-68 on March 1, 2000. The contained activity of the lost source has been computed to be 0.03 microCi (59000 dpm) as of the date of this notice. The exposure rate of a 1 microCi point (unsealed) source is 5.4 mR/hr at 1 cm; therefore, the exposure rate estimated for this sealed line source at 0.03 microCi is about 0.1 to 0.2 mR/hr at 1 cm. A description of the physical source is [as follows]. The source was manufactured by IPL (product code HEGL-0109) and is 6 inches in length and 1/8 inches in diameter with steel encapsulation.
"The source had been stored and not used (due to low activity), and was last inventoried (and leak-tested) on July 22, 2010. An investigation is currently underway to determine the disposition of this source, and will be submitted to the MDE RHP [Maryland Department of the Environment, Radiological Health Program] per D.1201b within thirty days of this notice."
The State of Maryland will be conducting a follow-up investigation.
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

| Event Text FAILURE TO PERFORM FFD KNOWLEDGE EXAMINATIONS FOR CONTRACTOR PERSONNEL
"SNC [Southern Nuclear Company] was informed on September 16, 2010 that the training records for a limited number of contractor employees, who are subject to the 10 CFR 26 subparts A through H, N and O requirements, did not include evidence of completion of the examination required by 10 CFR 26.29(b). The individuals had received training on the knowledge and abilities described in 10 CFR 26.29(a) but, due to personnel error, had not completed the testing required by 10 CFR 26.29(b) prior to being authorized to perform duties for which such examination is a prerequisite under 10 CFR 26. Authorization of the affected individuals to perform duties subject to 10 CFR 26 subparts A through H, N and O has been withdrawn until the required testing is completed in accordance with 10 CFR 26.29(b). Prior to discovery of this deficiency, enhancements to procedural guidance had been made to provide additional programmatic controls on subparts A through H, N and O required records. Since the procedural enhancements were implemented, required comprehensive examinations have been performed. SNC is providing this notification under the provisions of 10 CFR 26.719(b)(4) as a discovered vulnerability of the FFD program."
The licensee has started testing the above mentioned personnel and expect full compliance by the beginning of next week. They will be notifying the Public Service Commission of Georgia and the NRC Resident Inspector. |

"This is a one-hour report for the discovery of a condition that met an Emergency Activation Level (EAL) for a Notification of an Unusual Event [NOUE].
"EAL HU-1 - Natural and Destructive Phenomena Affecting the Protected Area Threshold Value 6 states, 'Exceed Max Normal Operating Values specified in EOP 31 EO-EOP-014-1 SC - Secondary Containment Control Table 5 Secondary Containment Operating Water Levels.'
"Plant Hatch Unit 1 declared a NOUE on 9/18/10 at 1627 based on HU-1 Natural and Destructive Phenomena Affecting the Protected Area due to exceeding the Max Normal Operating Value for the Reactor Building NE Diagonal Floor Drain Sump. At 1615, both the Level High and Level High-High annunciators alarmed. Water has not overflowed the sump. However, due to its design, it is not possible to immediately visually confirm the sump level. The sump pumps were not running and would not run with their switches in START indicating either: (1) there is no water in the sump, (2) both pumps are OOC [Out of Commission], or (3) there is a problem in the sump level control system. Maintenance is assessing the situation."
The licensee has notified the state and local agencies and will notify the NRC Resident Inspector.
* * * UPDATE FROM STEVE BURTON TO HOWIE CROUCH @ 0427 EDT ON 9/19/10 * * *
At 0400 EDT, the NOUE was terminated. The termination criteria was that the NE Diagonal Floor Drain Sump level was in its normal operating range with no abnormal sump in-leakage detected. Compensatory measures are in place to measure level in the sump. An investigation into the abnormal level indication is still in progress.
The licensee will be notifying state and local authorities as well as the NRC Resident Inspector. Notified R2DO (Henson), IRD (Gott), NRR EO (Howe), DHS (Inser) and FEMA (Via). |

"On 9/20/2010 at approximately 0700 EDT, the Hope Creek Safety Parameter Display System (SPDS) and the Emergency Response Data System (ERDS) will be taken out of service for approximately nine days to support a planned modification which will install a new (upgraded) computer system. During this timeframe, ERDS and SPDS will be unavailable. Should the need arise, plant status information will be communicated to the NRC, State and local responders using other available communication systems. SPDS and ERDS are expected to be restored on 9/29/2010. This event is reportable under 10 CFR 50.72(b)(3)(xiii) as a 'Major Loss of Assessment Capability'."
The licensee has notified Lower Alloways Creek Township and the NRC Resident Inspector of the planned outage. | |
