Sections F.1, G.1.d and G.1.e. of ZAP 620.07 require an individual use the SAME portal                        '

This refers to information provided to the NRC on May 13,1998, by personnel at the

[ morning a contractor employee exited the Zion Station after receiving two consecutive - i contamination alarms from two portal monitors located in the Zion Station gatehouse and did y

not wait for assistance from the Radiation Protection Department. Zion Administrative Procedure (ZAP) 620-07, " Proper Operation and Response to Contamination Monitors,"

requires that after an individual receives two consecutive alarms from the same portal monitor at the gatehouse, the individual must contact the Radiation Protection Departnmnt for i i - assistance prior to exiting the plant. In this case the individual attempted to cc tact the i
Radiation Protection Department, but the individual did not wait for their assistance. 1 The NRC Office of Investigations (01) conducted an investigation into the circumstances surrounding this issue and concluded that, based on the individual's training and experience, the individual deliberately failed to wait for assistance from the Radiation Protection Department and left the Zion Station after he received two consecutive contamination alarms. A copy of the 01 report synopsis is enclosed.

Therefore, the individual was not required to obtain assistance from the Radiation Protection Department and could leave the Zion Station

~ without delay. Hence, the NRC staff concluded that this specific instance did not constitute a j violation of NRC requirements and this enforcement action (EA)is closed.
