AUTOMATIC REACTOR SCRAM DURING TRANSMITTER VENTING
"At 0100, Nine Mile Point Unit 2 reactor scrammed [on low reactor water level]. The cause is currently under investigation. Maintenance activities were in progress on Residual Heat Removal (RHR) B & C systems. It is suspected that transmitter venting is the most probable cause of the trip. Reactor core isolation system (RCIC) injected on invalid level 2 signal. No safety relief valves (SRV's) actuated. B and C Residual Heat Removal systems (RHR) remain inoperable. All other ECCS systems and Emergency Diesel Generator are currently operable. Reactor water level is normal. No emergency core cooling system injection was required. The plant is currently in the hot shutdown condition. No emergency plan activation is required. Activation of forced outage plan is in progress.
"Lowest reactor water level reached during the transient was 140 inches. This is less than the reactor water level scram set point of 159.3 inches.
"Reactor pressure before scram was 1020 psig, current reactor pressure is 530 psig and reactor coolant temperature is 470 degrees F. Plant stack monitor is not available. Last grab sample reading at time 0257 is 857 micro-curies/sec.
"All systems functioned as required. All rods fully inserted on trip."
Decay heat is being removed by steaming to the main condenser. The plant is in its normal shutdown electrical lineup.
The licensee notified the NRC Resident Inspector.

OFFSITE NOTIFICATION TO STATE AND LOCAL AGENCIES CONCERNING RESULTS OF QUARTERLY GROUND WATER ANALYSIS
"On January 6, 2010, Vermont Yankee (VY) was notified that the results of fourth quarter 2009 ground water sampling, performed as part of the voluntary ground water monitoring program, identified a very low concentration of tritium in one well that is used to monitor station ground water. VY has notified state, local and other government agencies of this condition. Since no other wells indicated the presence of tritium and the concentration detected is below the reporting threshold identified in the Off-site Dose Calculation Manual, notifications were considered voluntary consistent with NEI 07-07 'Industry Ground Water Initiative - Final Guidance Document.' This report is being made in accordance with 10 CFR 50.72(b)(2)(xi) to notify the NRC of these voluntary notifications. There is no impact on public health and safety as a result of this event.
"The NRC Resident Inspector has been notified."

OFFSITE NOTIFICATION DUE TO THE DISCOVERY OF CONTAMINATED DOLLAR BILLS
"An individual entered the plant access and alarmed [the] portal radiation monitor. Upon investigation the individual's wallet contained three contaminated one dollar bills. The individual had processed out of similar monitors the previous day without indication of contamination. The three one dollar bills were surveyed and it was determined that they contained only I-131. The individual was interviewed and it was determined that the contaminated money was likely obtained at a local merchant. The individual is not aware of anyone undergoing iodine therapy. I-131 is used for therapy and diagnostic medical practices. The Corporate Health Physicist called the Nebraska Department of Health and Human Services, Radiological Health Division about the incident and location. The bills are contaminated above levels acceptable for the plant. The conclusion is that someone not associated with the power plant had iodine treatment, contaminated the bills, used them at the store and the individual received those bills as change.
"There is no reason to believe that contamination has any connection to the operation of power plant."
The licensee has notified the NRC Resident Inspector.
