SENTINEL Test Flan #70 Amersham Corporation September 17,1997 Burlington, Massachusetts Page 1 of $9 Amersham Test Plan #70 This document describes the package design test plan for Sentinel Model 660 Series projectors to meet NRC requirements for Type ll(U) packages (10 CFR 71.71 and 10 CFR 71.73). 'lhe test plan also covers the criteria ststed in I AEA, Safety Series 6 (1985, as amended 1990).
Quality Assurance will be involved si. sll aspects of this test plan and its execution.
The Model 660 Series includes the following models: 660,660A,66011,660E,660AE, and 66011E. Reference Certificate of Compliance 9033.
This document omiines the testing scenario, justifies the package orientations for the difTerent test specimens, and provides test worksheets to record key steps in the testing sequence.
1.0 Transport Package Overview 1he Model 660 Series projector consists of a source tube enclosed in a depleted uranium shleid, an end plate with a lock assembly, a second end plate with a storag plug assembly, four steel connecting rods, a sheet metal shcIl and foam packing material (Figure 1).

SENTINEL Test Plan #70 Amersham Corporation September 17,1997 Durlington, Massachusotts Pago 2 of $9 The 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. 'lhe other end of the shield's source tube is inserted into another 1/2 inch deep hole of the shipping plug at the front end-plate. Iloth 1/2 inch deep holes allow enough radial clearance for a slip fitting attachment. There is approximately 1/8 inch axial clearance at the front end for assembly.
1he source is contained in a special fonn, encapsulated capsule assembly which is attached to the source wire assembly. This source wire assernbly is secured in the package by the lock assembly. The lock assembly, in turn, is attached to the rear end plate by four #10-32 U.N.C.
stainless steel screws.1here are two versions of the lock assembly used on the Model 660 series projectors. The sire, material and location of the end plate attachment screws are identical on both versions.
'the shield, end plates and the sheet metal shell are connected by four 3/8 inch thick stecI rods w hich are threaded at each end to accept 1/4 inch screws securing the end plates to the rals.
A polyurethane foam is used to Gil the space around the shield and fill void within the sheet metal shell.1he foam acts as an impact absorber.
The depleted-uranium shield provides the primary radiation protection for the Model 660 Series projector. The shield accomplishes this by limiting the transmission of gamma rays to a dose level at or below 200 mler at the package surface 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.
%e location of the source relative to its stored position in the shield is also an important 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.
There are two possible scenarios to displace the source relative to its stored position:
The shield could move away from the source if the source tubes were bent or frac-tured during testing.
'lhe source could move 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.
'Ihe 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 shleid and which affect the integrity of the shield itself.
2.0 Purpose lhis purpose of this plan, which was developed in accordance with Amersham sop-E005, is to ensure the Model 660 Series projectors meet the Type 11 transport package requirements of 10 CFR 71.
The series includes these models: 660,660A,660B,660E,660AE, and 660BE. Refer to Appendix A for descriptive drawings of these models.
SENTINEL Test Plan #70 Amersham Corporation September 17,1997 Burlington, Massachusetts Page 3 of 69 1he Nonnal Conditions of Transport tests (10 CFR 71.71) to be perfonned are the compression i
test, penetration test and four foot free drop test.
1he water spray preconditioning of the package is not perfonned as the Model 660 projectors are constructed of waterproof materials throughout. The water spray would not contribute to any degradation in structural integrity.
1he llypothetical Accident Tests (10 CFit 71.73) to be perfonned are the 30-foot free drop, puncture test, and thennal test.
The crush test (10 CFR 71.73(c)(2))is not perfonned because the radioactive contents are special fonn radioactive material.
The immersion test and all other conditions specilled in 10 CFR 71 will be separately evaluated in accordance with Amersham Work Instruction Wi E08.
3.0 System Failures of Interest 1he 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 fonn 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 defonn 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.

lest Plan #70 Amersham Corporation Septemt>er 17,1997 Burhngton, Massachusetts Page 4 of 69 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.
4 Plunger Lock: *lhe lock mount containing the plunger lock functions as a locking index plunger for the selector ring, it does not hold the source wire assembly. Ifit 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, aller removal of the ship-ping cap and depression of the anti rotation lugs.
Ca rrying Ilandle: The handle provides no safety features to the device. its prima-ry function is as a carrying or lifling feature.
4.0 Construction and Condition of Test Specimens The test specimens will be Model 6601) units constructed in accordance with Amersham Drawing D66010, Rev. C, modified per Drawing TP70, Rev. ll. The units specified in Drawing TP70, Rev. II, are in accordance with the NRC approved design.
Drawing TP70, Rev. ll, specifies the Model 660 Series in its worst case transport condition, that is, with supplemental lead added to the shield. The added welght induces higher loads during dynamic testing.
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 sequired by IAEA, 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 shleid and the end-plate attachment scre ws.
Four test specimens, built to Drawing 'fP70, Rev. B, and the Amersham Quality Assurance Program, are to be tested, one for each possible failure mode:
Specimen A: Shield movement or fracture Specimen I3: Failure of the lock assembly attachment screws 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 inflicted on a specific component or assembly in the preceding test, it is important that each specimen maintain its identity throughout the battery of tests and that the setup instructions spec {fic to the specimen are strictlyfollowed Table I lists the differences between the test specimen and other 660 Series models.
SENTINEL Test Plan #70 I
Amersham Corporation September 17,1997 Burlington, Maasachusetts Page 6 of 69 Table 1: Model 660 Series Variations Test Specimen Feature per Drawing TP70, 660 Series Models Rev,11 Shell Material Stainless steel ne Models 660,660A,660AE and 660E can have either a carbon steel shell or a stainless steel shell.
All other models in the series use stainless steel.
Lock Asseinbly Posilok" ne Model 660 and 660E use a non Posilok lock assembly.
All other models feature the Posilok lock assembly.
Actuator Wirts No actuator wires and Models 660AE,660BE and 660E have wires and ccnnectors l
and Connecton connectors attached to ends plates for automatic actuation.
Models 660,660A and 660B do not have actuator wires and connectors.
Shield Capacity 140 Curie ne following models have 120-Curie capacity shields:
660,660A,660AE and 660E,
%e following models have 140-Curie capacity shields:
6608 and 660BE.
Body Width Standard width Some Model 660s and Model 660Es have a narrow body (51/4 inches) design (4 3/4 inches wide).
All other models only use the standard width body (51/4 inches).
Source 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 Supplen entallead Prior to June 1992, some units in the Model 660 Series had added lead added to supplement the shielding, ne maximum amount of lead added was 3 pounds. De amount was also limited by a maximum shield weight of 40 pounds and a maximum package weight of 56 pounds, Weight 54 pounds it.inimum Over the last five years, the average package weight has been approximately 50 pounds. Earlier in the product history, the average weight was approximately 53 pounds.
SENTINEL Test Plan #70 Amersham Corporation September 17,1997 Burlington, Massachusetts Page G of 59 1he differences listed in Table I do not affect the radiological safety of the projector for the following reasons:
Shell Materials: 'ihe shell thickness is 1/16-inch for the carbon steel and stainless stect 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 temperature for transition from ductile to brittle is lower for the thinner sections.
'ihe thicker carbon steel end plates will reach the ductile to brittle transition tem.
perature long before the shell does. 'the end plates are structural members, while the shell is not structurally significant.
Ieck 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 Posilok style assemblies used on the Model 660 and the Model 660lk
'Ihe internal components of both lock assemblies are protected by the same lock assembly cover and practically the same selector ring. The cover and selector ring raust be significantly dan. ged before an impact can disrupt the internal 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 same type and size attachment screws in the same locations.
Actuator Wires and Connectors: 'Ihe additional parts used for automatic actua-tion provide no structural support.
Shield Capacity: 'ihe lower capacity shields are either lighter than or the same weight as the shield used on the Model 6600, making the 660!! the worst case for shield failures ofinterest in these tests.
Ilody Width: 'ihe end plates and shells of the narrow body versions of the Model 660 and the Model 660B would provide smaller impact surfaces than the standard-width plates and shell used in the test specimen. The smaller impact surfaces would result in greater surface defonnation and less deceleration on impact. As a result there would be less transfer ofimpact forces that could affect the integrity of the source securement.
Sou rce Tube Material: 'lhe 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 curTently in use have titanium source tubes, the test specimens will be manufac-tured with titanium source tutws, llased on an evaluation of the damage caused by the tests, we will assess the implications for previously fabricated packages which utilized zirealoy.
Note that r.1 hough 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 in future fabrication.
SENTINEL Test Plan #70 Amorsham Corporation September 17,1997 Burlington, Massachusetts Page 7 of 69 Supplemental tendt Prior to June 1992, supplemental lead was used in the pro-duction of hiodel 660 Series projectors with the depleted. uranium shleid. Although the addition of supplemental lead is no longer a production technique, the TP70 test specimen will be fabricated with the supplemental lead to ensure the maximum de-Vice mass.
Package Weight Hecause of more emcient casting and the elimination of supple-mental lead shielding, the average weight of Model 660 units produced in the last Ove years is three pounds less than the average welght for units produced in the car-ly years of the series history. Two steps will be taken to build test specimens that will weigh at least 54 pounds:
lleavier depleted uranium shields will be fabricated.
Supplemental lead will be added to the shleid.
He TP70 will be consistent with current manufacturing procedures and will represent the heavier units in the Model 660 population. Ninety seven percent of all 660 units produced weigh 54 pounds or less.
5.0 Material and Equipment List The test worksheets in Section 7.0 list the key materials and equipment speelned in 10 CFR 71 and the necessary measurement instruments.
When video recording is specined in the following tests, select video cameras with the highest shutter speed practical to record testing.
Additional materials and equipment may be used to facilitate the tests.

l The compression test is followed by the penetration test per 10 CFR 71.7l(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. The bar is dropped through free air.
Use ChecAllst 2 penetration Test on page 43 to ensure that test sequence is followed. Date and initial all action itens and record required data.
NOTEt The worksheet identifies those steps which must be witnessed by Engineering.
Regulatory MJisirs and Quality Assurance.
The following describes the orientation of each test specimen immediately before the bar is dropped and the test evaluation for the test.
6.4.1 Penetration Test Setup
'there is a specific orientation for each specimen so that the penetration bar is aimed at the component or assembly ofinterest.
NOTEt Because each test is designed to add to damage irtflicted on a specific component or anembly 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 twlow.40' C,
- 2. Place the specimen on the drop surface (Drawing AT10122, Rev. B) 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 HT10129, Rev. B, directly above the specified point ofimpact, and raise the bar 40 to 42 inches above the target.
' SENTINEL Test Plan #70 Arnersham Corporation September 17,1997 Burlington Massachusetts Page 13 of 69 6.4.2 Specimen A Orientation for Penetration Test The penetration target for Specimen A is the hit marker on the left side of the package (when facing the lock assembly), as shown in Figure 3. There are two objectives for this orientation:
Move the shield and thus disrupt the source tube connections at either end plate liracture the shield This setup was chosen because the depleted-uranium shield is closer to the exterior on the left side than it is in any other location.

The final Normal 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 perfonn the first intermediate test inspections.
Use Checklist 3: Four-foot Free Drop on page 46 to ensure that the test sequence is fol lowed.
Date and initial all action items, and record required data on the worksheet.
NOTE:
The worksheet identifies those steps which must be witnessed by Engineering, Regulatory 4[ fairs and Quality An. trance.
6.5.1 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. B. There is a specific orientation for each specimen so that the package lands on the componu or assembly ofinterest.
NOTE:
Because each test is designed to add to damage inflicted an 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 aoe strictlyfollowed.
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 B.
- 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.

Test Plan #70 Amersham Corporation -
September 17,1997 Burlington, Massachusetts Page 19 of 69 6.5.2 Specimen A Orientation for Four-foot Free Drop The impact points are the bottom edges of the two end plates as shown in Figure 7. Align the center of gravity marker on the sides of the packages with the middle of the drop surface.
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 defonnation 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.

SENTINEL Test Plan #70 Amersham Corporation September 17.1997 Buriington, Massachusetts Page 20 of 59 6.5.3 Specimen B Orientation for Four-foot Free Drop The 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 D 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.
This 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.

The object in this drop is to disrupt the connection between the source tube and the shipping plug, which in turn could cause movement of the source. A secondary effect could be disruption of the connection between the source tube and the rear end-plate.

The bottom edge of the plate provides the greatest surface area for 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.

The following describes the orientation of each test specimen immediately before the package is dropped onto the billet and the test evaluation.
6.8,1 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 assembly in thepreceding test, it is important that each specimen maintain its identity throughout the trattery oftests and that the setup instructions specJic 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, f
This test uses the 12-inch high puncture billet (Drawing CT10119, Rev. C). The billet meets 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:
a 1.
Measure and record the weight of the package.
2.
Ensure that the package is at or below 40* C.
3.
Position it according to the specimen-specific orientation described below.
4.
Raise the package so that there is 40 to 42 inches between the package and the top of the puncture billet.

- 6.10 Thermal Test (10 CFR 71.73(c)(4))
i
%e final requirement is the thermal test specified in 10 CFR 71.73(c)(4).
To ensure sufficient heat input to the test specimens, each specimen will be pre-heated to a temperature of at least 800 C and held to at least that temperature for 30 minutes. This test condition provides heat input in excess of the requirements specified in 10 CFR 71.73(c)(4),
which does not include a pre-heat condition. The pre-heat condition assures equivalent heat input regardless of emissivity and absorptivity coefficients.
The test environment is a vented electric oven operating at 900 C. There will be sufficient air flow to allow combustion. Air will be forced into the oven at a minimum rate of 9.6 cubic feet per minute to ensure sufficient oxygen to fully combust all package materials that are capable of burning. This rate is based on the following analysis:
- 1. The only combustible material in the TP70 is the polyurethane foam.
2.
The chemical composition of polyurethane is [C 1I NO ]n.
26 33 i3
- 3. The products of combustion are carbon dioxide (CO ) and water (110) 2 2
and the molecular weights of the component materials are:
C = 12 11 = 1 O = 16 N = 14
- 4. The maximum mass of the polyurethane in a TP70 is 988 grams. The max-imum amounts of carbon and hydrogen present in the polyurethane are i
computed as follows:

32 For a given mass of carbon,32/12 = 2.67 times that mass of oxygen is required to fully combust the carbon to carbon dioxide. For a TP70 containing 543 grams of.
i carbon, full combustion would require 1450 grams of oxygen.

24 16 For a given mass of hydrogen,16/2 = 8 times that mass of oxygen is required to fully convert the hydrogen to water. For a TP70 with 57 grams of hydrogen, full combustion would require 456 grams of oxygen.
- 7. The sum of these oxygen requirements (1450g + 456 g) less the oxygen supplied by the polyurethane (-363 g) equals 1543 grams of oxygen to as-sure suflicient oxygen to burn the polyurethane foam. At standard condi-i tions, the composition of air is 23.2% oxygen by mass. Therefore,6650 grams of air are required.
8.
The volume of air is computed at a density of 1.225 grams / liter to be 192 cubic feet:
3 3
6650g/1.225g/l = 54301 = 5.43m =19211 9.
A 50% safety factor is added and the volume is distributed over the 30-minute test period to determine a minimum air flow rate of 9.6 cubic feet per minute:
3 3
(192 ft )(1.5) / 30 min. = 9.6 fl / min.
The air will be introduced as compressed air passing through a flowmeter acd into the oven via metal tubing. A sufficient length of tubing will be inside the oven to ensure sufficient pre-heating.
The temperature of the package's exterior surface closest to the air entry point will be monitored throughout the test to ensure that the package remains above 800* C.
If the specimen is buming when it is removed, the unit is allowed to extinguish by itself and then cool naturally. The final evaluation of the package is performed when the specimen reaches ambient temperature.

-Thermal Test To perform the thermal test:
- 1. Ileat the oven to 900* C.
- 2. Attach thermocouples to the package's internal and external measurement locations,
- 3. place the package in the oven and close the door.
4.
When the internal temperature of the package goes above 800* C, start air flow and start a 30-minute timer.
- 5. Measure and record the oven temperature, test specimen internal and ex.
ternal temperatures and the air flow rate. Record whether there is any com-bustion.
6.
Monitor the specimen's internal and external temperatures, and the oven temperature throughout the 30-minute test period to ensure that all temper.
atures remain above 800* C.
7.
Monitor the airflow rate throughout the test period to ensure that it remains 3
above 9.6 ft / minute.
8.
At the end of the 30 minutes, repeat Step 5.
9.
Remove the test specimen from the oven,
- 10. Allow the package to self-extinguish and cool.
