TURBINE ELECTRO-HYDRAULIC CONTROL MALFUNCTION LEADS TO REACTOR SCRAM
"At 1503 hours EDT, an Electro-Hydraulic Control (EHC) system malfunction caused the Unit 2 Main Turbine bypass valves (BPV) to start cycling. Initially, BPV 1 partially opened and closed followed shortly thereafter by four BPVs going full open. At that time the order was given to insert a manual scram. An automatic scram signal occurred just as the operator was beginning to insert the manual scram.
"Preliminary investigation of the automatic scram signal indicates that it was initiated by low Relay Emergency Trip Supply (RETS) pressure to the main turbine control valves due to the EHC malfunction. Reactor water level momentarily dropped below Low Level during the response. This resulted in Primary Containment Isolation System (PCIS) Group 2 and Group 6 isolations, as expected.
"All control rods fully inserted. All systems responded as designed. This report is being made in accordance with 10 CFR 50.72(b)(2)(iv)(B) due to the Reactor Protection System actuation and 10 CFR 50.72(b)(3)(iv)(A) due to the PCIS Group 2 and Group 6 actuations.
"Unit 1 was not affected by this event and remains at 100% power. The NRC resident inspector has been notified."

SURFACE CONTAMINATION ON RECEIVED PACKAGE EXCEEDING LIMITS
At 1600 EDT on 09/11/08, the RSO was notified of a contamination event by the Chief of Nuclear Medicine who was also notified today by the technician involved. The event occurred on Saturday, 08/30/08 at 1524 EDT when a technician received a Technetium 99 package from Cardinal Health in Fayetteville, NC for patient treatment. Initial swipe survey of package external surfaces showed 13,000 dpm of gamma contamination. Package was decontaminated to 1620 dpm and stored in the Hot Lab to decay and picked up on Monday, 09/01/08, by Cardinal Health with no contamination. The hospital is not aware of any internal contamination from the package, but will get a full statement from the technician involved on 09/13/08. Cardinal Health will be notified of the contamination issue on 09/13/08.
* * * RETRACTION PROVIDED AT 1630 EDT ON 09/12/08 FROM CAPT BALDOCK TO JEFF ROTTON * * *
Further investigation and discussion with NRC Region 1 DNMS (Michelle Simmons) has determined that the event is not reportable since the contamination level was below the maximum permissible limit of 220 dpm/sq cm for beta and gamma emitters.
Notified R1DO (Lorson) and FSME (Luehman).
