- This issue is dispositioned as an additional example of a previous licensee-identified non-cited violation (50-361/9808-01). The inspector determined that no broad additional corrective actions are warrante R8.2 (Closed) LER 50-361:-362/98013-01: FSAR Assumotion Not Evaluated in Control Room Post LOCA Dose Calculation Due to Personnel Error This licensee identified issue involved a dose calculation error resulting from the use of inappropriate assumptions. The inspector reviewed the licensee's corrective actions and determined that the error was a minor issu R8.3 (Closed) LER 50-361:-362/98015: Non-isokenetic Samplina of Airborne Effluent Streams The licensee identified that the condenser air ejector exhaust and containment main purge radiation monitors were not obtaining a representative sample for radioactive

-8-material in the particulate form and radioiodines as required by Technical Specification 5.5. Technical Specification 5.5.2.3(c) states, in part, " Monitoring, sampling, and analysis of radioactive gaseous effluents in accordance with the methodology and parameters in the Offsite Dose Calculation Manual (ODCM)." ODCM Section 2.1.1.2 states,in part,

"The dose rate due to radiciodines and radioactive materials in particulate form in gaseous effluents shall be determined by obtaining representative samples." The failure to obtain representative samples for radiciodines and radioactive materials in particulate form for the condenser air ejector exhaust and containment main purge is being identified as a Non-Cited Violation, consistent with Section Vll.B.1 of the NRC Enforcement Policy (50-361;-362/98020-01).

The licensee promptly corrected this issue by performing procedural changes to ensure that no main purges are performed using radiation monitors that would not obtain a representative sample and implementing the use of flow reducers to obtain the desired sample flow rates so that representative samples are obtaine V. Manaaement Meetinas X1 Exit Meeting Summary An exit meeting was conducted on December 11,1998. During this meeting, the inspector reviewed the scope and findings of the inspection as detailed in this repor The l~censee acknowledged the findings presented.
