in Support of Exclusive Use Radioactive Shipments'and Receipt af.Non Exempt- .

' " J Radicactive Packeges," did not requ ae any comparison between lurvey.results'at:the front of the shipping container and survey results in the cab' area. The HP-technician, therefore, did not recognize the disparity. An additional l causal factor-identified was that no.. procedural requirement for, independent. verification of survey results existed. Independent verification may.have offset the potential for human; ' l error. TheLGSdetector(JohnsonExtender 33-0705) was tested-satisfactorily _ .

following this event es were the detectors used at Quadrex.-therefore: instrument. s, malfunction'was eliminated;as_.a causal factor. '

Corrective Actions Taken-and Results! Achieved a.

On November 12, 1990, Quadrex's Radiation Safety Officer notified LGS, the State 01%

Corrective Actions Taken to Prevent Recurrence .

The HP technician involved was counseled on' the importance of attedion to detail-t when performing surveys. and was appropriately disciplined on' December 11.':1990. .

Procedure HP-715 has.been revised te add a note;to the attachment:on which; survey:

readings of the trailer are recorded exceed indicating l'.'6tmR/hr (thatt if dose;1.imit)

LGS administrative rates' .then measured 2; meters from- the'.

close attention:

should be paid to dose rates measured in the cab...ThisLw111 aid'in ensuring that?ifi dose rates in the cab exceed the LGS administrative? limit offl.6 mR/hr.the(

i This procedural non-compliance has-been reviewed, along with other procedural l non-compliances noted in the inspection report,_as'part of ourJongoing ~

self-assessment process. We will continue to review these types of. issues and-

, implement corrective actions as'necessary to_further minimize personnel errors.

including those involving procedural:non-compliance. '

Date-When full Compliance was Achieved-Full compliance with-associated Regulatory requirements was achieved on November 12,- -

1990, at 1734= hours, upon_ completion of allfappropriate notifications. Compliance-has been achieved-upon revision ~of procedure HP-715 and notification of these_ changes-to affected'HP personnel.- This event-is considered to be an isolated occurrence. The counseling / discipline of the involved HP technician, the enhancement of HP-715, and-the performance of an independent verification'of survey.results'are considered

-sufficient corrective measures, e
