"At 1740 CDT, VA-81A, Hydrogen Analyzer Panel, was declared not functional due to failing surveillance test OP-ST-VA-0006, Containment Hydrogen Monitor Monthly Check. VA-81B, Hydrogen Analyzer Panel, was previously not functional due to performance of surveillance test IC-ST-VA-0033, 18 Month Channel Calibration of Containment Hydrogen Analyzer, VA-81B.
"This results in no Hydrogen Analyzers being available to monitor containment, which prevents being able to assess for potential loss of containment barrier for Emergency Action Level purposes via the containment hydrogen greater than 3% method.
"USAR [Updated Safety Analysis Report] section 9.10.2.5 allows for both Hydrogen Analyzers to be out of service for up to 72 hours. "
The licensee informed the NRC Resident Inspector.
* * * RETRACTION FROM ERICK MATZKE TO JOHN KNOKE AT 1152 EDT ON 9/29/10 * * *
"Fort Calhoun Station had previously reported that the loss of both hydrogen monitors on September 15, 2010, constituted a major loss of emergency response assessment capability. Additional investigation has determined that other methods of assessment were available that would have provided sufficient indication to make the proper emergency classification. Therefore, this event is being retracted."
The licensee has notified the NRC Resident Inspector. Notification was sent to R4DO (Thomas Farnholtz). |

The following information received via email is historical and was discovered/reported to the State of Ohio on 04/27/2010:
"NOTE: The information entered in this event notice was received from the licensee as a result of an audit ordered by the Ohio Department of Health for all brachytherapy procedures performed by the licensee since November 2004. This incident was referenced in Ohio NMED Item # OH100003. [NMED Item Number: 100113 - Ohio Agreement State Report EN #45750]
"On 12/2/04 the licensee performed a prostate seed implant with I-125 seeds prescribed to deliver a dose of 160 Gray [107.4 Gray actually delivered] to the prostate. A post implant dose calculation showed a underdose to the prostate greater than 20% of the prescribed dose; however, the licensee determined the dose to be clinically adequate. No further therapy was planned at that time. [Ohio NMED Item # OH100012]
"On 12/14/04 the licensee performed a prostate seed implant with I-125 seeds prescribed to deliver a dose of 108 Gray [66.27 Gray actually delivered] to the prostate. Post implant dosimetry showed a low dose distribution to the base of the prostate, which was not felt to be clinically significant. No further therapy was recommended at that time, since the patient also received external beam radiotherapy. [Ohio NMED Item # OH100013]
"On 7/3/07 the licensee performed a prostate seed implant with I-125 seeds prescribed to deliver a dose of 160 Gray [101.82 Gray actually delivered] to the prostate. A post implant dose calculation showed a underdose to the prostate greater than 20% of the prescribed dose; however, the licensee determined the dose to be clinically adequate. There was limited dose distribution at the gland base. No further therapy was planned at that time. [Ohio NMED Item # OH100014]
"On 1/11/05 the licensee performed a prostate seed implant with I-125 seeds prescribed to deliver a dose of 160 Gray [101.7 Gray actually delivered] to the prostate. A post implant dose calculation revealed a suboptimal dose distribution to the base of the prostate gland. No further therapy was planned at that time. [Ohio NMED Item # OH100015]
"On 7/14/05 the licensee performed a prostate seed implant with I-125 seeds prescribed to deliver a dose of 160 Gray [57.4 Gray actually delivered] to the prostate. Following the final dosimetry testing in 2005, the patient and the referring urologist were notified of a clinically suboptimal dose to the base of the prostate. Post implant prostate volume on which the dosimetry was calculated was 40% greater than the intraoperative prostate volume. Thus, dosimetry was inaccurate due to gland edema. The patient and the referring urologist opted for close monitoring of the prostate and PSA levels without additional therapy. No further therapy was planned at that time. [Ohio NMED Item # OH100016]
"On 4/17/07 the licensee performed a prostate seed implant with I-125 seeds prescribed to deliver a dose of 108 Gray [58.6 Gray actually delivered] to the prostate. Seed implant was utilized as a boost to the prostate gland following IMRT. Post implant dosimetry showed a suboptimal dose distribution at the base; however, satisfactory dose was observed about the mid gland where biopsy proven adenocarcinoma was present. No further therapy was planned at that time. [Ohio NMED Item # OH100017]
"On 9/23/05 the licensee performed a prostate seed implant with I-125 seeds prescribed to deliver a dose of 108 Gray [79.4 Gray actually delivered] to the prostate. The patient received external beam radiation therapy (4500cGy) and seed implant was utilized as a boost to the prostate gland following IMRT. Post implant dosimetry indicated a clinically satisfactory dose distribution. No further therapy was planned at that time. [Ohio NMED Item # OH100018]"

| Event Text AGREEMENT STATE REPORT - MEDICAL MISADMINISTRATION
The following report was submitted via e-mail:
"On January 16, 2008, Saint John Medical Center (SJMC) Lic. # OK-00376-02, of Tulsa, OK notified the Oklahoma Department of Environmental Quality (ODEQ) that on January 10, 2008 a patient had been administered a dose of I-131 that differed from the intended dose by greater than 20%. The intended dose was 100 mCi. The administered dose was 25 mCi. The misadministration occurred because the 100 mCi dose provided by Nuclear RX, PC (NRX) Lic. # OK-31035-01MD of Tulsa, OK was divided among three capsules. Two capsules contained 25 mCi, while the third contained 50 mCi I-131. The bottle received by SJMC was opaque and stated that it contained one capsule of 309 mCi because of a software error at NRX. When the dose was administered to the patient, one capsule was dispensed from the bottle, while the other two stuck in the bottom of the bottle. The presumed empty bottle was then repackaged and shipped back to NRX where it was discovered that two capsules remained in the bottle. It was determined that the capsules contained a total of 75 mCi I-131. The capsules were not discovered before shipping because the tech at SJMC errantly surveyed the package before placing the bottle inside. Corrective actions by SJMC involve surveying the bottle prior to returning it to the transport shielding, refresher training on transport requirements in 49 CFR, and determining the transport index (TI) by survey outside of the hot lab. Corrective actions by NRX included contacting the software developer for an update that would ensure that all shipments are accurately labeled. NRX also agreed to write the number of capsules contained in each bottle on the lid of the bottle.
"Due to an oversight, this event was not reported at the time it was received by ODEQ."

The following report was received via e-mail:
"During the last radiographic exposure on 9/22/10 the source did not fully retract. The workers did not do a survey and did not have their rate alarms turned on. They noticed that their dosimeters were off scale and discovered the problem. The film badges were processed on 9/24/10 by Landauer and found the assistant radiographer received 0.742 Rem and the lead [radiographer] received 114.4 Rem. Since they were both together this is questionable. Landauer reports the lead's badge shows an uneven surface reading which is an indication it has been damaged by dropping. Licensee calculations show 0.750 REM for both. The lead has been sent for a blood test. Licensee will send a written report. Florida is investigating."
The camera contained a 71 Ci Ir-192 source.

"On September 29, 2010, at 1024 EDT, the Control Room Emergency Ventilation system on St. Lucie Unit 1 was declared out of service due to pre-planned maintenance on the Unit 1 Control Room ventilation system. This maintenance renders the control room envelope out of service for a portion of the maintenance. The Technical Support Center (TSC) ventilation system is part of the Unit 1 Control Room Emergency Ventilation system, therefore, the TSC ventilation system has been rendered non-functional during the course of the work activities. The TSC ventilation is expected to be returned to service later today.
"If an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing emergency planning procedures. Should the TSC become uninhabitable, the TSC staff will relocate to an alternate TSC location in accordance with applicable site procedures.

Dresser Masoneilan initiated a 10 CFR Part 21 investigation because of the failure of three (3) Air Regulators (model number 77N-40) at the PSE&G Salem Station within three months of being installed. Upon testing and evaluation, Dresser Masoneilan concluded that the internal O-ring used for pressure isolation in the Air Regulators were damaged during factory assembly contributing to the failure of the units to regulate pressure. Dresser Masoneilan has developed a corrective action plan and an in-service test method and acceptance criteria to determine if a unit is experiencing pressure loss due to the issue. Due to the volume, age and distribution of these models, Dresser Masoneilan is issuing a general notice to all utilities.
