Summary of Benchmark: Exelon Corporate - direction is to count samples to ODCM
Oyster Creek - They do not release soil, stock on site in "landfill" TMI - Liter of soil geli scanned with no peaks. How many samples is a judgment call on how much soil. Maybe 1 liter per scoop. Expect most contaminants in the first foot down Quad - They keep most of the soil on site. If they do free release the soil, they take samples every few feet and have chemistry do an isotopic analysis. They do not check for Tritium as long as the dirt is dry but if they did check they would use 20,000 pCi/L as a limit Palo Verde - Palo Verde uses a 1 liter marinelli, and gamma spec to less than the environmental levels for solids listed in the ODCM. They only check for tritium if there is liquid / water present. If the soil is "moist" it's dried before it is disposed of / released. We assume all tritium that maybe be present is HTO (water form) therefore no moisture in soil = no water = no tritium. SONGS - Sampled (typically 1 L) and gamma spec'd by site chemistry to MDAs no greater than the environmental levels listed in the ODCM CENG-RE Ginna NPP - Sampled (typically 1 L) and gamma spec'd by site chemistry to MDAs no greater than the environmental levels listed in the ODCM. They do not count for tritium. St. Lucie - Sampling requirements are by procedures and ODCM. They consider tritium in some cases. This decision is made by RP using process knowledge and historical information. They included programmatic information to review. Amanda L.
