MEETING REPORT DATE: September 15, 2005 TIME: 10:00 am - 12:30 pm PLACE: One White Flint North 11565 Rockville Pike Rockville, Maryland 20852 PURPOSE: Status of Ground Water Remediation and Monitoring Activities ATTENDEES: Refer to Attachment A BACKGROUND:

The licensee, the Connecticut Yankee Atomic Power Company (CY), requested a meeting to present the current status of ground water remediation and monitoring activities at the Haddam Neck Plant.

DISCUSSION:

CY presented results and status in the following areas: Review of License Termination Plan (LTP) compliance criteria, soil characterization, tank farm bedrock contamination, groundwater monitoring, groundwater modeling, future monitoring plan, groundwater recharge and recovery, and planned actions prior to the start of the 18 month groundwater monitoring period.

LTP Compliance Criteria: CY reviewed the LTP criteria relative to groundwater dose calculations, release criteria, and the use of a capture zone analysis and monitoring period to demonstrate successful final status survey.

Soil Characterization Results: CY described the extent of soil remediation and characterization for the site industrial area. CY will sample the soil in all suspect areas to bedrock or 24 feet below grade. Most of the soil sampling is complete, and the only remaining expected remediation below the normal water table is bedrock removal in the former tank farm area.

Tank Farm Bedrock Contamination Status: CY has observed radiological contamination in bedrock fractures in the former tank farm area, which were characterized with down-hole gamma spectroscopy and laboratory analysis. The deepest observed contamination was 11 1/2 feet below the top of bedrock. Fractured bedrock exceeding CYs groundwater screening criteria will be removed by blasting.

Groundwater Monitoring: CY described strontium-90 and tritium plumes observed in the June 2005 sampling event, which show low levels of contamination in confined and unconfined aquifers on site. CY has replaced two of the monitoring wells, based on apparent seal leaks between the two aquifiers.

Enclosure

Groundwater Modeling: CY described groundwater modeling results which appear to show that industrial area groundwater discharges to the Connecticut River.

Future Monitoring Plan: CY described the future monitoring well network, overlaid with the groundwater modeling data, to demonstrate the likely adequacy of the future well monitoring network.

Groundwater Recharge and Recovery: Well level data from August to September 15, 2005 were presented. CY concludes that the site groundwater table has returned to normal levels.

Start of 18 Month Groundwater Monitoring Period: CY indicated their intent to commence their 18-month groundwater monitoring period with the September 2005 quarterly sampling event.

ACTIONS:

The U.S. Nuclear Regulatory Commission staff indicated they would consider CYs intent to start groundwater monitoring and discuss the issue further by telephone conference in a few weeks.
