Harsh, Project Director, NRR D. Hartland, Resident Inspector Enforcement Conference An Enforcement Conference was conducted by telephone between NRC Region III personnel and Indiana Michigan Power Company personnel on March 2, 1993.
The purpose of the conference was to discuss the circumstances surrounding the January 26, 1993, shipment of an empty container which previously contained a box with a contaminated filter pump.
The package was sent to the guadrex Recycle Center and upon arrival was found to exceed Department of Transportation radiation limits of 0.5 mrem/hr over a small surface of the package.
An inspection was conducted on February 2 through 5,
1993, and the inspection findings were documented in Inspection Report Nos.
50-315/93007(DRSS)
and 50-316/93007(DRSS),
transmitted to the licensee on February 19, 1993.
The conference agenda included (1)
a discussion of the apparent violations, their causes and safety significance, the licensee's corrective actions, and areas of concern, (2)
a determination if there were any escalating or mitigating circumstances, and (3) obtaining further information which would help determine the appropriate enforcement action.
The licensee identified two inaccuracies in Inspection Report Nos.
50-315/93007(DRSS)
and 50-316/93007(DRSS).
The licensee described the events which led to the apparent violations, including the root cause and contributing causes, safety significance,
.
and their corrective actions.
The licensee indicated that the event was an isolated problem with no likely potential for an exposure to a member of the public.
The corrective actions are described in the attached copy of the licensee's handouts.
These actions will be reviewed during future inspections.
At the conclusion of the conference, the licensee was informed they would be notified in the near future of the final enforcement action.

~ Safety Significance
~ Concluding Remarks
BACKGROUND
~ History and Shipping of Sea Van QG-27
~ Sea Van contained pump from another nuclear plant shipped via Vendor facility for use in.Cook Plant Spent Fuel Pool Reracking job.
~ Work performed limited to removal of pump from container.
~ Survey for Sea Van return shipment indicates maximum dose rate less than 0.2 mremihou BACKGROUND Continued
~ Cook Plant Notification and Vendor Surve Resul s
~ Cook Plant notified on January 27, 1993 that dose rate limitfor empty container was exceeded.
~
endor receipt survey indicates localized contact dose rate of 38Q mrem/hour.

BACKGROUND Continued
~ Subsequent Cook Plant Action
~ Vendor was requested to leave Sea Van undisturbed.
Vendor stated they could not comply with request.
~ Spectral analysis of particle was requested
- Vendor agreed to do.
~ Cook Plant representative arrived at Vendor on January 29, 1993 to examine Sea Van and confirm conditions.
~ Spectral analysis of particle was not performed by Vendor - Vendor disposed of particle.
~ Cook Plant.was unable to verify Sea Van.radiological condition ROOT AND CONTRIBUTING CAUSES
~ Root Cause
~ nadequate pre-shipping dose rate survey of the Sea Van
~ Contributing Causes
~ Dose rate meter used for the survey was of a t e
not optimally suited for surveying an empt container
~ Small localized source size and location of article increased the difficultyof detection
PREVENTIVE ACTIONS
~ Immediate
~
n ependent surveys of all outgoing radioactive material shipments
~ Policy Letter
~
n ependent surveys of all outgoing radioactive material shipments
~ Utilization of optimal available instrumentation
~ Management expectations
~ Completed February 18, 1993
PREVENTIVE ACTIONS Continued
~ Procedure Revision
~ Independent surveys of all outgoing radioactive material shipments
~ Utilization of optimal available instrumentation
~ Checklist for "empty package" shipments
~ Completed March 1, 1993
~ Training for Radiation Protection personnel
~ Description of the event
~ Selection and use of optimal available equipmen
~ Proper survey methodologies
~ Completion date:
March 31, 1993
SAFETY SIGNIFICANCE
~ Chance of Inadvertent exposure to public was negligible
~ Direct route of shipment to Vendor
~ Minimal stops made by driver
~ Overnight storage in fenced and secured enclosure
~ Contact dose rate was less than that allowed for radioactive material shipment
~ Nature of the discrete particle:
~ To receive measurable dose, person must be:
~ in very close proximity to source
~ in direct line from source
~ Dose rate one meter away (inside Sea Van) was one millirem per hour
CONCLUDING REMARKS
~ This event had minimal safety significance
~ Preventive actions were promptly implemented to prevent recurrence
~ Cook Plant historical performance with respect to radioactive material shipping has been excellent
