Amersham Test Plan #70
'Ihis document describes the package design test plan for Sentinel Model 660 Series projectors to meet NRC requirements for Type B(U) packages (10 CFR 71.71 and 10 CFR 71.73). *lhe test plan also covers the criteria stated in IAEA, Safety Series 6 (1985, as amended 1990).
'Ihe Model 660 Series includes the following models: 660,660A,660B,660E,660AE, and 660DE. Reference Certincate of Compliance 9033.
'Ihis document outlines the testing scenario,justines the package orieritations for the difTerent test specimens, and provides test worksheets to record key steps in the testing sequence.
1.0 Transport Package Overview
'the Model 660 Series projector consists of a source tube enclosed in a depleted-uranium shield, an end plate with a lock assembly, a second end plate with a storage plug assembly, four steel connecting rods, a sheet metal shell and foam packing material (Figure 1).

%e shield consists of a 1/2 inch outside diameter source tube with its mid section set in depleted uranium. One end of the source tube is inserted into a 1/2-inch deep hole of the lock assembly at the rear end-plate. %c other end of the shield's source tube is insened into another 1/2 inch deep hole of the shipping plug at the front end plate. Both 1/2 mch deep holes allow enough radial clearance for a slip fitting attachment. %cre is approximately 1/8 inch axial clearance at the front end for assembly.
De source is contained in a special form, encapsulated capsule assembly which is attached to the source wire assembly. His source wire assembly is secured in the package by the lock assembly. De lock assembly, in turn, is attached to the rear end plate by four #10-32 U.N.C.
stainless steel screws. nere are two versions of the lock assembly used on the Model 660 series projectors. He size, material and location of the end-plate attachment screws are identical on both versions.
ne shield, end plates and the sheet metal shell are connected by four 3/8 inch thick steel rods which are threaded at each end to accept 1/4 inch screws securing the end plates to the rods.
A polyurethane foam is used to Gil the space around the shield and fill void within the sheet metal shell. De foam acts as an impact absorber.
%e depleted uranium shield provides the primsrv radiation protection for the Model 660 Series projector. De shield accomplishes this by limitiag the transmission of gamma rays to a dose level at or below 200 mR/hr at the package sur; ace and limiting the dose level at or below 10 mlUhr at one meter from the surface of the package. A fracture of the shield could compromise this protection.
He location of the source relative to its stored position in the shield is also an imponant safety element. A large displacement of the source relative to its stored position could elevate the dose at the surface of the package above regulatory limits.
Here are two possible scenarios to displace the source relative to its stored position:
De shield could move away from the source if the source tubes were bent or frac-tured during testing.
De source could snove away from the shield if the lock assembly became loose or was removed from the end plate or if the end plates themselves became loose or were removed during testing.
He tests in this plan focus on damaging those components of the package which could cause the displacement of the source relative to its stored position within the shield and which affect the integrity of the shield itself.
2.0 Purpose His purpose of this plan, which was developed in accordance with Amersham SOP-E005, is to ensure the Model 660 Series projectors meet the Typ D transport package requirements of 10 CFR 71.
The series includes these modtis: 660,660A,660B,660E,660AE, and 660BE. Refer to Appendix A for descriptive dra vings of these models.
l SENTINEL Test Plan #70 Amersham Corporation August 18,1997 Durlington. Massachusetts Page 3 of 60 He Nonnal Conditions of Transport tests (10 CFR 71.71) to be performed are the compression test, penetration test and four foot free drop test.
He water spray preconditioning of the package is not performed as the Model 660 projectors are constmeted of waterproof materials throughout. He water spray would not contribute to any degradation in structural integrity.
The flypothetical Accident Tests (10 CFR 71.73) to be performed are the 30-foot free drop, puncture test, and thennal test.
The crush test (10 CFR 71.73(c)(2)) is not performed because the radioactive contents are special fonn radioactive material.
The immersion test and all other conditions specified in 10 CFR 71 will be separately evaluated in accordance with Amersham Work Instruction Wi E08.
3.0 System Failures of Interest The possible system failures which could occur during test conditions and affect package integrity:
3.1 Shield Movement or Fracture Elevated dose levels and depleted uranium contamination may result if the shield were to move or break as a result of high shock loading.
3.2 Lock Assembly Screws Elevated dose levels may result if the lock assembly with source assembly attached were to be removed or damaged as a result of high impact loading.
Dispersal of special form contents is highly unlikely since the encapsulated source assembly meets the requirements of special form and is protected at the center of the shield.
3.3 Shipping Plug and Source Tube Connection A direct impact on the shipping plug could deform the end plate in towards the shield. An impact could also damage the source tube connection allowing the shield to move.
3.4 End Plate Attachment Screws The loss of the rear end-plate would result in loss of the lock assembly as well and cause exposure of the source. The loss of the front plate may indicate that the loss of the rear plate is just as likely.
M-(
SENTINEL Test Plan #70 Amersham Corporation August 18,1997 Burlington, Massachusetts Page 4 of 50 3.5 Other System Failures Two other possible system failures were considered but rejected because damage to these components would not cause damage to safety-related components.
Plunger Lock: The lock mount containing the plunger lock functions as a locking index plunger for the selector ring. it does not hold the source wire assembly, if it were to fall, the source would continue to be secured in the lock assembly. The se-lector ring can only be rotated during operation, that is, after removal of the ship-ping cap and depresion of the anti rotation lugs.
Carrying llandle: The handle provides no safety features to the device, its prima-ry function is as a canying or lifting feature.
4.0 Construction and Condition of Test Specimens The attched test specimen drawing (Drawing TP70, Rev. A) specifies the Model 660 Series test specimen in its worst case transport condition, that is, with lead added to the shield. This added shield weight provides the maximum mass of the device.
Except for the compression and thennal tests, the test temperature of the specimen must be below -40" C at the time of each test, a minimum temperature required by I AEA, Safety Series 6 (1985, as amended 1990), The low temperature represents the worst-case condition for the package because of the potential for brittle fracture of the shield and the end-plate attachment Scre ws.
Four test specimens, built to Drawing TP70, Rev. A, and the Amersham Quahty Assurance Program, are to be tested, one for each possible failure mode:
Specimen A: Shield movement or fracture Specimen D: Failure of the lock assembly attachment screws a
Specimen C: Loss of the connection between the storage plug and the source tube Specimen D: Failure of the end-plate attachment screws NOTE:
Because each test is designed to add to damage IqRicted on a specffic component or assembly in the preceding test, it is important that each specimen maintain its identity throughout the battery oftests and that the setup instructions spec {fic to the specimen a~e strictlyfollowed
%c test packages will be Model 660B units constructed in accordance with Amersham Drawing D66010, Rev. C, modi 0ed per Drawing TP70, Rev. A.
Table 1 lists the difference between the test specimen and other 660 Series models.

Lock Assembly Posilok*
The Model 660 and 660E use a non Posilok kick assembly.
All other models feature the Posilok lock aarmbly.
Actuator Wires No actuator wires and Models 660AE,660!!E and 660E have wires and connectors and Connectors connectors attached to ends plates for automatic actuation.
Models 660,660A and 660!! do not have actuator wire and connectors.

The following models have 140-Curie capacity shields:
66011 and 66013E.
Body Width Standard width (51/4 Some Model 660s and Mode! 660Es have a narrow body inches).
design (4 3/4 inches wide).
All other units use the standard width body (51/4 inches).
Soutw Tube Titanium Prior to 1980, the Models 660,660A,660AE and 660E were Material manufactured with zircaloy source tubes.
All other units have titanium source tubes.
Use of Lead Lead added to shield Some Model 660 Series units in all models have lead added to the shield in an amount equal to or less than the amount used in the test specimen.
~lhe differences listed in Table I do lot afTect the radiological safety of the projector for the following reasons:
Shell Materials: The shell thickness is 1/16-inch for the carbon steel and stainless steel versions. The likelihood of a crack or brittle flaw increases with the thickness of the section and is a problem in sections greater than 1/8 inch. Additionally, the te.nperature for transition from ductile to brittle is lower for the thinner sections.
The thicker carbon steel end plates will reach the ductile to brittle transition tem.
perature long before the shell does. The end plates are.:tructural members, while the shell is not structurally signincant.
Lock Style: Damage to the Posilok lock assembly used on the test specimen would represent damage to any Model 660 Series lock assembly, including the non Posi-lok style assemblies used on the Model 660 and the Model 660E.
N
'Q SENTINEL Test Plan #70 Amersham Corporation August 18,1997 Burlington, Massachusetts Page 6 of 50 The internal components of both lock assemblies are protected by the same lock assembly cover and practically the same selector ring 1he cover and selector ring must be significantly damaged before an impact can disrupt the intemal components' securement of the source. Because of the strength of the cover and the selector ring, damage to the source securement is more likely to occur from the failure of the lock assembly attachment screws. All models use the stane type and size attachment screws in the same locations.
Actuator Wires and Connectors: 1he additional parts used for autematic actua-tion provide no structural support.
Shield Capacity: The lower capacity shields are either lighter than or the same
. weight as the shield used on the Model 660tl, making the 660B the worst case for shield failures ofinterest in these tests.
Hody Width: The end plates and shells of the narrow body versions of the Model 660 and the Model 660E would provide smaller impact surfaces than the standard.
width plates and shell used in the test specimen.1hc smaller impact surfaces would result in greater surface defonnation and less deceleration on impact. As a result -
there would be less transfer of impact forces that could affect the integrity of the source securement.
Sou rce Tube Material:1he Model 660 Series projectors have been manufactured with titanium source tubes exclusively since 1980. Because this represents our cur-rent manufacturing methods and because the majority of Model 660 Series units currently in use have titanium source tubes, the test specimens will be manufac-tured with titanium source,bes. Based on an evaluation of the damage caused by the tests, we will assess the implications for products fabricated with zircaloy.
Note that although listed on the descriptive drawings, stainless steel source tubes have never been used in the fabrication of Model 660 Series units, nor do we intend to use them la future fabrication.
Lead Added: The addition oflead to the shield creates a worst case condition by increasing the weight of the sh: eld.
5.0 Material and Equipment List The test worksheets in Section 7.0 list the key materials and equipment specified in 10 CFR 71 and the necessary measurement instruments.
Additional materials and equipment may be used to facilitate the tests.

Page 11 of 50 6.3 Penetrat!on Test (10 CFR 71.71(c)(10))
The compression test is followed by the penetration test per 10 CFR 71.71(c)(10), in which a penetration bar is dropped from a height of at least 40 inches to impact a specified point on the package. He bar is dropped through free air.
Use Checklist 21 Penetration Test on page 40 to ensure that test sequence is followed. Date and initial all action items and record required data.
NOTE:
The ucrksheet identifies those steps which must be witnessed by Engineering, Regulatory Afairs and Quality Assurance.
The following dese bes the orientation of each test sp cimen immediately before the bar is dropped and the pass / fail criteria for the test.
6.3.1 Penetration Test Setup There is a specific orientation for each specimen so that the penetration bar is aimed at the component or assembly ofinterest.
NOTE:
Because each test is designed to add to damage inflicted on a specific component or assembly in the preceding test, it is important that each specimen maintain its identity throughout the battery oftests and that the setup instructions specific to the specimen are strictlyfollowed.
This test requires that the test specimen be at or below -40* C at the time of the penetration bar release. The worksheet calls for measuring and recording the specimen temperature before and after the test.
To set up a package for the penetration test:
- 1. Measure the specimen's internal and surface temperature to ensure that the package is at or below -40 C.
2.
Place the specimen on the drop surface (Drawing AT10122, Rev. A) and position it according to the specimen-specific orientation described below.
- 3. Use steel shims to position the package, if necessary.
4.
Position the penetration bar shown in Drawing BT10129, Rev. A, directly above the specified point ofimpact, and raise the bar 40 to 42 inches above the target, h

6.4 Four-foot Free Drop Test (10 CFR 71.71(c)(7))
The final Nonnal Transport Conditions test is the four-foot free drop as described in 10 CFR 71,71(c)(7). This drop compounds any damage caused in the first two tests. Upon completion of this step, you will perform the first intermediate test inspections.
Use Checklist 3: Fourfoot Free Drop on page 42 to ensure that the test sequence is followed.
Date and initial all action items, and record required data on the worksheet.
NOTE:
The worksheet identajies those steps which must be witnessed by Engineering, Regulatory Afairs and Quality Assurance.
The following describes the orientation of the test specimens prior to the drop and the pass / fait criteria for the test.
6.4.1 Four-foot Free Drop Setup In this test, the package is released from a height of four feet and lands on the steel drop surface specified in Drawing AT10122, Rev. A. There is a specific orientation for each specimen so that the package lands on the component or assembly ofinterest.
NOTE:
Because each test is designed to add to damage inflicted on a specific component or assembly in thepreceding test, it is important that each specimen maintain its identity throughout the battery oftests and that the setup instructions specific to the specimen are stric:lyfollowed.
This test requires that the test specimen be at or below -40 C at the time of the drop Follow the Worksheet instructions for measuring and recording the specimen temperature before and after the drop.
To set up a package for the four-foot drop test:
- 1. Use the drop surface specified in Drawing AT10122, Rev A.
2.
Measure the specimen's internal and surface temperature to ensure that the package is at or below -40 C.
- 3. Place the specimen on the drop surface and position it according to the specimen-specific orientation described below.
4.
Raise the package so that the impact target is 4.0 to 4.5 feet above the drop surface.
5.
Align the selected center of gravity marker as shown in the referenced drawing.

%e impact points are the bottom edges of the two end plates as shown in the Figure 7. Align the center of gravity marker on the sides of the packages with the middle of the drop su. face.
His orientation attempts to break the connection between the source tube and the end plates, and move the shield away from the source. Each end plate provides a rigid structure which limits defomiation and directs the shock load to the source tube connections of the shield The momentum of the shield toward the bottom of the package may cause the end plates to separate from the shell.

Drawing AT10122 Rev.A Figure 7: Specimen A Orientationfor Four-foot Drop Test As the bottom edges make contact with the drop surface, the plates rapidly decelerate while the downward momentum of the shield (the heaviest component in the package and the center of gravity) increases the likelihood of damaging the source tube-to-end plate connections. The shield may act as a wedge forcing the end plates apart. The downward momentum may also have the secondary effect of moving the source.

= Amersham Corporation August 18.1997 Burlington, Massachusetts Page 19 of 50 6.4.3 Specimen B Orientation for Four-foot Free Drop He four foot drop setup for Specimen B is shown in Figure 8. The object of the drop is to shear or loosen the lock assembly screws and damage the connection with the shield.
The impact point is the outer edge of the lock assembly cover. It is important to position test specimen B so that its center of gravity is directly above the lock assembly.
The impact will add to any damage to the lock assembly caused by the penetration bar in the second test.
His orientation directs the maximum obtainable shear force to the lock assembly attachment screws in an attempt to move the lock and the source. Other orientations for attacking the lock assembly would not benefit from the center of gravity aligned with the impact position and/or would be limited by interference from the plate edges.

Here, the objective is to loosen or shear the end-plate screws which hold the plate to the steel connecting rods. The bottom edge of the plate provides the greatest surface area fbr a direct hit, and thus the most rapid deceleration Other locations were rejected as follows:
The top edge provides less than half the surface area of the bottom edge, and much of the load would be directed through the carrying handle.
. The curved side edges would only provide a point impact.
The lock assembly and the shipping plug would interfere with a direct hit to the face of their respective end plates, Dropping the package on any corner would absorb the impact energy by deforming the end plate into the foam.
Make sure the center of gravity is directly over the point ofimpact,

SENTINEL Test Plan #70 Amersham Corporation August 18.1997 Burlington, Massachusetts Page 29 of 50 6.7 Puncture Test (10 CFR 71.73(c)(3))
The 30-foot free drop is followed by the puncture test per 10 CFR 71.73(c)(3), in which a package is dropped from a height of at least 40 inches onto the puncture billet,specified in Drawing CT10119, Rev. C.
The billet is to be bolted to the drop surface used in the free drop tests (Figure 15).
Use Checklist 5: Puncture Test on page 46 to ensure that test sequence is followed. Date and initial all action items and record required data.
NOTE:
The worksheet identifies those steps which mmt be witnessed by Engineering.
Regulatory Affairs and Quality Assurance.
The following describes the orientation of each test specimen immediately before the package is dropped onto the billet and the pass / fail criteria for the test.
6.7.1 Puncture Test Setup There is a specific orientation for each specimen so that the package lands on the component or assembly ofinterest.
NOTE:
Because each test is designed to add to damage inflicted on a specific component or a.ssembly in the preceding test, it is important that each specimen maintain its identity throughout the battery oftests and that the setup ir.structions specific to the specimen are strictlyfollowed.
This test requires that the test specimen be at or below -40" C at the time of the test. The worksheet calls for measuring and recording the specimen temperature before and after the test.
This test uses the 12-inch high puncture billet (Drawing CT10119, Rev. C). The billet mxts the minimum height (8 inches) required in 10 CFR 71.73(c)(3). The specimen has no projections or overhanging members longer than 8 inches which could act as impact absorbers, thus allowing the billet to cause the maximum damage to the specimen.
To set up a package for the puncture test:-
- 1. Ensure that the package is at or below -40 C.
2.
Position it according to the specimer-specific orientation described below.
- 3. Raise the package so that there is 40 to 42 inches betwe n the package and the top of the puncture billet.
4.
Check the alignment of the specified center-of-gravity marker with the tar-geted point ofimpact.

Figure 15 through Figure 18 illustrate the four package orientations for the puncture tests. The
-justification for each orientation is the same as the orientation for the specimen's free drops.
6.7.2 Specimen A Orientation for the Puncture Test The objective of the Specimen A orientation (Figure 15) is to puncture the shell and move the shield. The impact area is the bottom of the psckage, the largest flat surface on the shell. This surface will yield the greatest deceleration, while the momentum of the shield continues downward. Align the center of gravity marker on the side of the package with the center of the puncture billet.

The bottom edge provides the largest, unobstructed flat surface on the plate. 'Ihe impact will crush the bottom of the end plate into the polyurethane foam, the sollest material in the pac and cause the maximum distortion of the plate. Attacking the top edge was rejected because the flat surface area is less than half that of the bottom edge and the carrying handle would deflect much of the energy.
