SUBJECT:

RADIOACTIVITY RELEASES FROM IPEC - NOVEMBER 2006 This report summarizes monthly gaseous, particulate, radioiodine and liquid radioactive effluents from IPEC as prescribed in the unit's Offsite Dose Calculation Manuals.

Tables 1 and 2 provide the current percent of ODCM limits (quarterly, annual, and 31-day dose projection). The following table illustrates current proximity to the Station and Stretch Goals, in percent. These goals are defined as 10% and 1% of the most restrictive ODCM annual. limit, respectively.

Year: 2006 AIMost 2 (imitinuinaliimi*It i Mostlirhitin* annhial1limit IP3i Station Goal (10% ODCM) 0.853 % of goal 0.0687 % of goal Stretch Goal (1% ODCM) 8.53 % of goal 0.687 % of goal Effected Limit Noble6Gas Beta Air mrad- i Airborne i&P Doseý.-

from releases associatedwith 2R17 from H-3 in routine ventilation Unit 2:

Efficient liquid waste processing continues following 2R1 7. The Sphere Foundation Drain Sump totalizer was replaced in July with a modern ultrasonic instrument. The calculated flow rate from the SFDS decreased from previous assessments as a result. The North Curtain Drain cleanup skid has effectively removed all identified Cs-137 from this pathway, despite some added groundwater to this pathway. The digital background to the liquid waste radiation monitor (R-54) was adjusted in October to better match grab sampling.

Routine VC samples no longer quantify Kr-85. VC Pressure Reliefs occur approximately every 3 days.

Unit 3:

Minimal volumes of liquid waste were processed during the month. The cleanup skid continues to operate efficiently.

The tritium inventory in liquid waste remains the most limiting challenge for liquid effluents.

While noble gas releases are very low, airborne tritium is the most limiting pathway at IP3. The source of this activity is the Spent Fuel Pool and the ventilation system in the FSB (run to keep the building negative per the General Design Criteria). VC Pressure Reliefs occur approximately every 4 days.

31-day Dose Projection:

Radiological waste cleanup systems are normally used at all times at IPEC (for ALARA concerns). The ODCMs, however, require their use if a 31-day dose projection indicates doses may exceed prescribed limits.

The unit 1 processing skid has been modified with some temporary repairs and containment to control small leaks from the vessels. A plan has been drafted for permanent repair/replacement in 2007. There is currently no restriction in our ability to apply sufficient ALARA efforts and meet the 31-day dose projection criteria.

However, additional containment and repair may be required to ensure continued operability of this system.
