                2.    Purpose                                                                      ;
                h e purpose of this reactive inspection was to examine the circumstances
                surmniing the shipment of a loaded SeaVan by the licensee to the Quadrex            l
                Recycle Center, Oak Ridge, Tennessee. Upon receipt of the shipment at Quadrex,
                external radiation levels were found at the botta of the trailer used to
                transport the SeaVan in execss of those set forth in 49 CFR 173.441. Towards
                this end, the inspector reviewed all available records of this shipment, and
                Wgent actions taken by the licensee.
                3.    Chronology of Events
                On June 29, 1989, the ingw+e conducted a reactive inspection of the records
                for a shipraent of radioactive material as described below.
                On June 20, 1989, the liransee shipped a SeaVan containing bagged trash and a
                B-25 container to the Owirex Recycle Center in Oak Ridge, Tennessee. Quadrwx
                was contracted to sort tha waste material, compact loose trash, decontaminate
                roccverable items, and dispose of the resultant radwaste.
                The B-25 container held a Reactor Water Cleanup Pump 1rpeller Blade which was
                placed in a 55-gallon drum with lead blankets above and below the impeller blade
                to act as shielding and to fill the void spaces within the drum. S e drum was      q
                braced within the B-25 container to prevent tipping during transport. Prior to
                loading the SeaVan, on May 31, 1989, the licensee surveyed the top of the 55-      l
                gallon drun, ard found a maximum contact radiation level of 1.4 Roentgens per
                                                                                                  '
                hour (R/hr). We top and sides of the B-25 container had a myimnm contact
                radiation le,rel of 160 millircentgens per hour (mR/hr). he licensee did not
                survey the bottom of the 55-gallon drum nor the bottom of the B-25 container.
                Prior to shipment to Quadrex, the licensee surveyed the flatbed trailer on which
                the SeaVan was lmded and fourd a maximum contact reading on the bottora of the
                trailer of 190 mK/hr. Licensee procedures in effect on June 21, 1989 allowed      {
                release of a vehicle as long as the contact radiation level was less than the        !
                U.S. Department of Transportation limit of 200 mR/hr (49 CFR 173.441(b)(2)) .      1

                On June 21, 1989 at 1645 hours, the trailer was surveyed upon arrival at                            !
                Quadrex. 'Ihis survey showed a maximun: contact radiation level, on the bottom of
                                                                                                                    '
                the trailer, of 250 mR/hr. 'Ihis is an apparent violation of 49 GR
                173.441(b)(2), which requires, in part, that at no time during trano rart ray the
                external radiation level on the surface of a transport vehicle carry
                radioactive materials (includirg the top ard bottom of the vehicle) exceed 200
                mR/hr (50-352/89-14-01).
                At 1000 hours on June 22, 1989, Quadrcx left a message for a member of the
                licensco's staff to call them regarding the SeaVan shipment. At 1500 hours on
                June 22, 1989, a licensee representative spoke with the Quadrex staff and was
                informed of the results of the incoming survey. 'Iho licensee then notified the
                NRC Resident Inspector.
                On June 26, 1989, a representative of the licensee spent the day at the Quadrex
                Recycle Center conductirq surveys of the SeaVan and its contents. 'Ihe Quadrex
                staff had already removed the SeaVan from the trailer, and thus the licensee was
                unable to duplicate this survey result. Maximum contact radiatic1 levels of
                1100 mR/hr under the B-25 container aM 500 mR/hr under the SeaVan were noted by
                the licensee's representative.
                Subcequent to this event, the licensee has revised a plant procedure (HP-715) to
                lower the release limit for vehicles carryirq radioactive materials from 200
                mR/hr to 160 mR/hr.
                4.  Exit Interview
                'Ibe @r met with licensee representatives denoted in Section 1 at the
                conclusion of the inspection on June 29, 1989. 'Ihe inspator summarized the
                scope of the inspection and the irqxction findirgs. At no time durirg the
                inspection were written materials given to the licensee by the inspector.
