Statement of Reauest: - During an NRC inspection conducted on August 4-7,1998, a weakness was identified in the Sout Texas Project implementation of the emergency plan. The exercise weakness involved the failure to recognize that a dose projectionindicated the need to m*e. protective action recommendations ! beyond ten (10) miles. SouthTexas Project was requested to provide the corrective actions an !- schedule for completion of the actions to the comminion.
.
II. Causes of the Weakness: Ineffective Communications
The Dose Assessor completed a dose assessment as soon as possible once the release
l commenced. This dose nue.ument was signed by the Dose Assessor and delivered to the l Radiologica1 Director as the initial dose assessment for the release. The Dose Assessor l recognized the thyroid dose at 10 miles exceeded Protective Action Guidelines, however, t ! was not clearly communicated to the Radiological Director. i l
Job Performance Standards Not Adequately Defined '
Between the initial dose assessment and the time the supplemental Offsite Message was L transmitted, two additional dose assessments were performed, which were not required to be ' transmitted to the Radiological Director. The Radiological Director examined the supplemen Offsite Message prior to its submittal to the Emergency Director for signature. A lack of questioning attitude was displayed when the Radiological Director only checked transcription of the dose projection values on the form and did not ensure Protective A Recommendations were provided for alllocations that exceeded Protective Action Guidelines Insufficient Dose Assessment Equipment l- When the dose exceeds Protective Action Guidelines at ten miles, the preprinted Protective
i Action Recommendations on the STAMPEDE dose assessment report are incomplete in tha ' Protective Action Recommendations for areas beyond 10 miles are included. The only visu clue to the Radiological Director that the Protective Action Recommendations were not appropriate was the dose of 5.285 rem CDE at 10 miles printed on the report. i
