l 7.' Oneratine Procedure 7.1 Procedure for Loadine the Packare l 1. Ensure that the source is locked into place in its storage position. The source assembly must be fully inserted into the source tube and the lock plate engaged between the spiral wrap of the teleflex cable. Actuate the lock with its key. Repeat this process for each source assembly to be installed. Place the hat on the 820 and secure with the eight bolts. Attach a tamper proof security seal with an identification mark to two of the drilled bolt heads. 2. Assure all the conditions of the Certificate of Compliance are met and the model 820 has all the required markings. 3. If the 820 is to be packaged in a crate or other outer packaging, the outer packaging must be strong enough to withstand the normal conditions of transport. These requirements are outlined in 10 CFR 71. The 820 should be put in the outer package with sufficient blocking to prevent shifting during transportation. 4. Perform a radioactive contamination wipe test of the 820. This consists of rubbing filter paper i or other absorbent material, using heavy finger pressure, over an area of 46.5 in.2 (300 cm ) of 2 the package surface. The activity on the filter paper should not exceed 0.001 uCi of removable contamination. Also perform a contamination wipe on the outer package if used. 5. Survey the 820 with a survey meter at the surface and at a distance of 40 inches (Im) from the i surface to determine the proper radioactive shipping labels to be applied to the package as required by 49 CFR 172.403. If radiation levels above 200 mR/hr at the surface or 10 mR/hr at 40 inches (Im) from the surface are measured, the 820 must not be shipped. Also survey the outer package if used. 6. Return the 820 to Amersham Corporation according to proper procedures for transporting l radiocctive material as established in 49 CFR 171-178. NOTE: The U.S. Department of Transportation, in 49 CFR 173.22 C requires each shipper of Type B quantities of radioactive material to provide prior notification to the consignee of the dates of shipment and expected arrival. 7.2 Procedure for Unicadine the Packwe The consignee of a package of radioactive material must make arrangements to receive the package when it is delivered. If the package is to be picked up at the carrier's terminal,10 CFR 20.205 requires that this be done expeditiously upon notification ofits arrival. Upon receipt, survey the package with a survey meter as soon as possible, preferably at the time of pickup and no more than three hours after it was received during normal working hours. Radiation levels should not exceed 200 milliroentgen per hour at the surface of the exposure device, nor 10 milliroentgens per hour at a distance of 40 inches (Im) from the surface. Actual radiation levels should be recorded on the receiving report. If the radiation levels exceed these limits, the package should be secured in a Restricted Area, and the appropriate personnel notified in accordance with 10 CFR 20. l All components should be inspected for physical damage. i i The radioisotope, activity, model number, and serial number of the source and the package model number Revision 2 7-1 Feb 1997

4 and serial number should be recorded. Opening and operation of the 820 will be performed in accordance with the operation manual supplied with a the 820 in accordance with 10 CFR 71.89. 7.3 Prenaration of an Emory Packace for Transport 1. For shipment of an empty source changer first assure the changer does not contain an i unauthorized source or cropped source by performing a physical verification using the following procedure. NOTE: Use only the gauge provided with the source changer. Do not use any other tool or a gauge for another device. If you do not have the proper gauge to perform the test, contact Amersham 4 Corporation before conducting the test. Insert the proper gauge in the empty tube (s) of the source changer. Read the gauge at the a. top of the outlet fitting. b. The gauge should bottom out in the empty source tube and indicate a safe condition (the redline should be flush with the top of the source tube). Verify that each empty tube indicates a safe condition and proceed to step 2. c. If the gauge indicates an unsafe condition (the red line is above the source tube) there may be an obstruction in the tube. Remove the gauge slowly while observing the survey meter. If the radiation levels increase as the gauge is being removed keep the gauge within the device, secure the device and contact Amersham Corporation for further instructions. If radiation levels remain normal as the gauge is being removed, completely remove gauge and contact Amersham Corporation for shipping instructions. 2. When you have assured the container is empty, install the cover of the source changer and insert the closure bolts. Seal wire through the heads of two bolts. 3. Perform a radioactive contamination wipe test of the outer shipping package. This consists of rubbing filter paper or other absorbent material, using heavy finger pressure, over an area of 46.5 2 in.8 (300 cm ) of the package surface. The activity on the filter paper should not exceed 0.001 uCi of removable contamination. 4. When you have assured the Model 820 is empty, survey the device and prepare the package for transport depending upon the radiation levels obtained, as given in 49 CFR 173. 4 i Revision 2 7-2 Feb 1997

8 Accentance Tests and Maintenance Procram 8.1 Accentance Tests 4 8.1.1 Visual Insnection The package is visually inspected to assure: 1. It was constructed property in accordance with the drawings referenced in the Cenificate 1 of Compliance for the 820. 2. The labels are inspected to assure they contain the required information given in 10 CFR 71.85(c) and 10 CFR 40.13. 3. De source assembly used in this device is visually inspected to assure proper closure of the weld, to maintain primary containment. It is also inspected for proper length to assure it locks in the required storage position. 2 8.1.2 Structural and Pressure Tests i ne swage coupling between the source capsule and cable is subjected to a static tensile test with a load of 100 lbs. (445N). Failure of this test will prevent the source assembly from being used. 8.1.3 Leak Tests De radioactive source capsule (the primary containment) is wipe tested for leakage of radioactive contamination and must be less than 0.005 microcuries. The source capsule is also subjected to a vacuum bubble leak test Failure of either of these tests will prevent use of this source assembly. 8.1.4 Component Tests ne lock assembly of the package is tested to assure that security of the source will be maintained. Failure of this test will prevent use of the package until is corrected and retested. 8.1.5 Tests for Shieldine Intecrity i The radiation levels at the surface of the package and at 40 inches (Im) from the surface are measured using a small detector survey instrument (i.e. AN/PDR-27). These radiation levels, when extrapolated to the rated capacity of the package, must not exceed 200 milliroentgens per hour at the surface nor ten milliroentgens per hour at 40 inches (Im) from the surface of the package. Failure of this test will prevent use of the package. 8.1.6 Thermal Accentance Tests Not Applicable 8.2 Maintenance Procram 8.2.1 Structural and Pressure Tests Revision 2 8-1 Feb 1997
