HYDRAZINE RELEASE TO SETTLING POND EXCEEDED ALLOWED RELEASE RATE
"At 2355 on 12/30/04, the National Response Center was notified that the environmental release limit for hydrazine had been exceeded. A maximum of 3.8 pounds of hydrazine was released over an 8 hour period which exceeded the reportable quantity of one pound in 24 hours. A feed and bleed of the condensate system was in progress in preparation for plant startup. The release limit was exceeded due to a higher than expected concentration of hydrazine in the condensate system. The cause of the event is under investigation. The hydrazine addition was secured and draining of the system has been terminated. All of the hydrazine has been contained in a settling pond within the protected area."
The licensee notified the NRC Resident Inspector.
