i 7.2 Procedure for Unloadina the Packaae l

NOTES: a.

A radioactive material package must be accepted from the carrier at the time it.is delivered, b.

If a rad N Mive material package is to be held at the carr W 1 terminal for pickup, arrangements must be made tv teceive notification from-the carrier of the arrival of the package at the time of arrival.

The' package must be picked up expedit.iously.upon receipt of notification (within three hours if prac -

ticable).

1.

Upon receipt of a package of radioactive material, survey the exterior surfaces of.the package and assure that the maximum radiation level does not exceed-200-mrem /hr.

Survey three feet from the.. exterior surfaces of the packages and assure.that the maximum radiation i

level does not exceed 10 mrem /hr.

If either of these i

limits are exceeded, notify the Radiation. Safety Offi-(

cer immediately.

Record the maximum radiation levels measured at the package surface and at three feet from i

the package surface on the Receiving Report.-

2.

If the package contains radioactive material which is not in special form make a contamination wipe test of the exterior surface of the package.. Wipe a represen-tative surface of the package, covering an area of approximately 100 square centimeters, using a cloth patch and moderate pressure.

Measure =the activity of the patch using the contamination monitor and assure

~

that the activity does not exceed 0.01 microcurie.

If

[

this limit is exceeded, notify.the Radiation. Safety l

Officer immediately.

Record the results of this-con-3 tamination wipe test on the Receiving Report.

j Note:

If any of these limits are exceeded, the Radiation i

Safety Officer shall immediately notify the USNRC and t

the final delivering carrier.

(

3.

Inspect the package for any evidence of p'hysical dam-l age.

Record the results of this inspection on the.

Receiving Report.

Also-record on the Receiving Report i

the source model number, source serial number, radionu-o clide, activity, transport package model number and package serial number.

Forward a copy ~of the completed' Receiving Report to the' Radiation Safety Officer, i

1 7.3 Procedure for Preoaration of an Emotv Packace for Transport 1.

For shipment of an empty Model 850 source changer, first assure the changer does not contain an. unauthorized source or cropped source by performing a physical certification using the following procedure.

NOTE:

Use only the gauge provided with 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 I

test, contact Amersham Corporation before-conducting the test.

a.

Insert the proper gauge in the empty tube (s) of the source changer.

Read

't e gauge,at the top.of the outlet fitting.

I b.

The gauge should bottom out in the' empty source tube and indicate a safe condition (green signal).

• Verify that each empty tube indicates a safe condition and-proceed to step 2.

I If the gauge indicates an unsafe condition (red sig-c.

nal) there may be an obstruction.in the tube.

-Remove the gauge slowly while observing the' survey meter.

If the radiation levels increase as.the gau removed keep the gauge within the device,ge is being I

secure ~the device and contact Amersham for further instructions.

If the radiation levels remain normal as the gauge is being removed, completely remove gauge and contact Amersham Corporation for shipping instructions.

d.

When you have assured the container is empty,_ attach capty tag to source changer, insert shipping' plugs..

Install the shipping plates, secure each with the'4 bolts and seal wire with a securing seal through the drilled head of 2 of the bolts of each shipping plate.

l 2.

If the shipping package is to be placed inside a crate

}

i or other_ outer-packaging, the outer packaging must-be-l strong enough to withstand the normal conditions _of transport and must not reduce the: safety of _the-' pack--

age.

The shipping package must be placed within the l

outer package with sufficient blocking to' prevent:

shifting during transportation.

NOTE:

When using a crate or.other outer packaging to ship the 850, steps 3-4 refer.to the crate or outer packaging.

s 7-8 Revision 1 October 1990 4

3.

Assure that the levels of removable radioactive contamination on the outside surface of the outer. package do j

not exceed 0.001 microcurie per 100 square centimeters.

4.

Survey the package at the surface and at one meter from the surface to determine the proper shipping labels to be applied to package.

l a.

If the surface radiation level does not exceed 0.5 mrem /hr and there is no measurable radiation level at one meter from the surface, no label is required.

Mark l

the outside of the package with the proper shipping l

name and identification number (Radioactive Material, Articles Manufactured from depleted Uranium, UN 2909) i i

and the statement:

" EXEMPT'FROM SPECIFICATION PACKAGING SHIPPING: PAPER AND CERTIFICATION, MARKING AND LABELING AND EXEMPT FROM THE REQUIREMENTS OF 49CFR part 175 PER CFR173.421-1 AND 49 CFR173.424."

I NOTE:

This does not exempt the shipment from the reporting l

requirements listed in-49 CFR parts 171-177 pertain-ing to the reporting of the contamination or other t

radiation incidents.

Additionally, a notice must be enclosedEin'~or on-the package, included with the' packing. list ur otherwise forwarded with the package.

The' notice must include the name of the consignor or consignee and the state-ment:

t "This package conforms to the conditions ans limita-tions specified in 49CFR173.424 for Exemptsa Radioac-tive Material, Manufactured from Depleted. Uranium, UN 2909."

b.

If the surface radiation level exceeds 0.5' mrem /hr, or if there is a measurable radiation level at oneLueter from the surface, use the criteria of-table 1'in sec-

-)

tion 7.1 to determine the properfshipping labels to be applied to the package'with the proper shipping-name and identification number;(Radioactive Material,' LSA, i

n.o.s., UN 2912).

If_the container is packaged inside.

3 l

a crate or other outer packaging,-. mark the package with:

the statement "INSIDE PACKAGE. COMPLIES WITH; PRESCRIBED SPECIFICATIONS".

Properly complete'the' shipping papers', as~ listed'in section.7.1.

_The isotope is_U-238 and approximately 7 millicuries.

MODEL 850 ACCEPTANCE TESTS AND MAINTENANCE PROGRAM 8.1 Acceptance Tests l

8.1.1 Visual Insoection The package is visually inspected to assure:

1.

It was constructed properly in accordance with drawing number 85090 2.

The labels are inspected to assure they contain the required information as referenced in Section 7.

l 3.

The source assembly used in this device.is visual-

~

ly 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.

8.1.2 Structural and Pressure Tests The swage coupling between the source capsule and: cable is subjected to u static. tensile test with a load of 100 pounds.. Failure of this test will prevent the source assembly from being used.

8.1.3 Leak Tests The radioactive source capsule (the primary contain-ment) is wipe tested for leakage.of radioactive contam-ination.

The source capsule is subjected to a vacuum bubble leak-test.

The capsule is'then subjected to a second wipe test for leakage <of-radioactive contamina-tion.

The contamination must be less than 0.005 micro-l curies.

Failure of any of these tests will prevent use-of this source assembly.

The. package is wipe tested on the exterior. surface prior to its first1 shipment in accordancewith10CFR71.g7.- ~(If this wipe test' exceeds i

0.001 microcuries/100 cm. it will not be shipped.)'
