STD-R-02-012 1.0 GENERAL INFOMATION 1.1 Introduction The purpose of the following document is to provide the information and engineering analysis that demonstrates the performance capability and structural integrity of the HN-194S Cask and its compliance with the requirements of 10CFR71.

1.2 Packaos Description The HN-194S Cask is a top-loading, shielded container designed specifically for the safe transport of radioactive waste materials in Type A quantities and greater than Type A quantities of low specific activity radioactive waste materials between nuclear facilities and waste disposal sites.

The radioactive materials can be packaged in a number of different types of disposable containers.

The HN 194S Cask is a primary containment vessel for radioactive materials.

It consists of a cask body, a primary cask lid, and a secondary cask lid being basically a top opening right circular cylinder which is on its vertical axis.

Its principal dimensions are 81-5/8 inches outside diameter by 80 1/2 inches high with an internal space of 75-5/8 inches diameter by 741/2 inches high.

1.2.1 Packaaina The cask body is a steel annulus in the form of a vertical oriented, right circular cylinder closed on the bottom end.

The side walls consist of a 1-1/2 inch thick inner steel shell and a 1-1/2 inch thick O

outer steel shell.

The bottom is three inches thick and is welded integrally to tha internal steel body cylinder.

The steel shells are further connected by welding at the bottom of the cask and by welding ouwuwam ILJ

ST0 R-02-012 O

to a concentric top flange designed to receive a Buna-N 0-ring seal.

Positive cask closure is provided by the gasket seal and the thirty 1-inch holddown studs.

Four cask tiedown lugs and three cask lifting lugs are welded to the outer steel shell.

HN 194S casks have two (2) possible drain plug configurations.

Both have the drain plug entering horizontal to the cask bottom.

These configurations allow the cask to be drained with minimum operational

exposure, l

The primary cask lid is three inches thick and is stepped to mate with the upper flange of the cask body and its closure seal.

Three steel j

lifting lugs are welded to the primary cask lid for handling.

The primary cask lid also contains a secondary cask lid at its center.

The secondary cask lid is three inches thick and is fabricated in a design similar to the primary cask lid.

It has a Buna-N 0 ring seal and uses sixteen holddown studs to provide positive closure. The secondary cask lid also has a lifting lug located at its center to facilitate handling.

The shipping cask has two closure systems:

(1) the primary cask lid is closed with thirty 1 inch studs and a Buna-N 0 ring seal, (2) the secondary cask lid is closed with sixteen 1/2 inch studs and the same seal system used for the primary cask lid but smaller.

The shipping cask tiedown system consists of two sets of crossed tiedown cables (total of 4) and a shear ring (affixed to the vehicle O

load bed) designed to firmly position and safely hold the cask during transport.

Weld shear strength is assumed to be 15,600 psi.

l 2.4 General Standards for All Packanes O

This section demonstrates that the general standards for all packages are met.

l l

t lit" " WH 22

STD R 02-012 2.4.1 Chemical and Galvanic Reaction The shield is constructed from heavy strsetural steel plates. All exterior surfaces are primed and painted with high quality epoxy base paint.

There will be no galvanic, chemical or other reactions among the packaging components.

2.4.2 Epsitive Closure s

The HN-1945 cask has a three inch thick steel primary cask lid. The primary cask lid is secured to the cask using thirty 1 inch studs.

The studs provide metal to metal contact between the cask and the j

primary cask lid and compress an 0-ring seal to provide a positive closure.

The closure is designed to withstand an internal pressure of 1/2 atmosphere (7.35 psi) or a corner impact without elongating the

]

studs an amount that would allow leakage.

The secondary cask lid located in the center of the cover is secured with sixteen 1/2 inch studs. An 0 ring seal is used to provide positive closure.

2.4.3 Liftino Devices 2.4.3.1 Shicoino Cask i

Three equally spaced lugs are welded to the upper steel flange and the outer steel shell of the cask body.

The cask is lifted using these lugs, slings, and a suitable crane.

The lifting lugs are designed to lift three times the weight of the cask with no stresses in excess of their yield stress.

See Section 2.10.1 for analysis and details.

2.4.3.2 Primary Cask tid

)O The lifting devices for the primary cask lid consist of three equally spaced lugs welded directly to the outside of l

1 u9 n:es os nss 23

STD-R-02 012

v the primary cask lid. These lifting devices will support three times the weight of the cask lid with no stresses in excess of their yield stress.

See Section 2.10.2 for analysis and details.

2.4.3.3 Secondary Cask Lid The lifting device for the secondary cask lid consists of a single lug welded directly to the upper or cutside of the steel plate which is the second ey cask lid.

This lifting device will support three time; the weight of the secondary cask lid with no stresses in excess of its yield stress.

See Section 2.10.3 for analysis and details.

2.4.3.4 liftina Lua Covers O

Since the primary and secondary lid lifting lugs are not capable of supporting the full weight of the package, they will be covered during transit.

2.4.3.5 Liftina Lua Failure The lifting lugs are more than capable of supporting a load equal to three times the package weight.

Should the lugs experience a load great enough to cause a failure, the lugs will shear out locally before any detrimental effects compromise the integrity of the package.

2.4.4 Tiedown Devices 2.4.4.1 Tiedown Forces The tiedown devices consist of four ratchet binder and cabit assemblies attached from the tiedown lugs on the cask to 1197A (5 09 M 88 24

(3 STD-R 02 012 V

tiedown lugs on the trailer body. Additionally, a shear ring firmly positions and holds the cask on the trailer bed.

The tiedown lugs have been designed to allow the cask to withstand a vertical force of two times the weight of the cask, a transverse force of five times the weight of the cask, and a longitudinal force of ten times the weight of the cask with no resulting excessive stresses.

See Section 2.10.4 for the analysis and details.

2.4.4.2 Non-Liftina Attachments Covered The four tiedown lugs located on the cask periphery are covered when not in use with tiedown assemblies to prevent their use as lifting devices.

O 2.4.4.3 Tiedown Device Failure The four tiedown lugs on the cask periphery have been designed so that loads transmitted by the tiedown cables under the worst conditions will neither damage the outer steel shell nor cause the tiedown lugs to fail.

The tiedown system analysis is shown in Section 2.10.4.4.

2.5 Standards for Tvoe B and Larcer Quantity Packaaina This section is not applicable to the HN 1945 cask.

2.6 Hermal Conditions of Transport The HN 1945 package has been designed and constructed, and the cor, tents are so limited (as described in Section 1.2.3) that the performance requirements specified in 10CFR71.35 will be met when the package is subjected to the normal conditions of transport specified i

I ti m s en :en 25

STD-R-02-012 l

in Subpart F of 100FR71.

The ability of the RI-194S package to l

satisfactorily withstand the normal conditions of transport has been

[

assessed as described below.

2.6.1 lital i

Since the package is constructed of steel, temperatures of 130*F j

will have no effect on the package.

i 2.6.2 C_qld l

i The steel materials selected for plate and bolting each retain l

structural integrity at temperatures down to 40'F.

2.6.3 Pressure 5

The PN-194S cask will withstand an internal pressure of 1/2 atmosphere (7.35 psig).

This analysis is contained in Section 4.0, i

"Containment", specifically Section 4.2.1.

l 2.6.4 Vibration The cask tiedowns firmly position the package to minimize any l

vibrational effects.

In addition, all cask external devices are firmly attached (either by welding or bolting) to the cask.

l Specifically, the design closure consisting of the 0 ring seal for i

both the primary and secondary lid closures are capable of I

withstanding higher temperatures and forces than the cask experiences I

during nora l transpcrt conditions.

In a similar manner, the number

}

of bolts and the strength of the bolting design for the closures

{

assure that the bolts will not fail during normal transport.

STD R-02-012 2.6.5 Water Soray Since the cask external shell is constructed of steel,, this test is not required.

2.6.6 Free Droo The cask has been analyzed to ensure its structural adequacy to withstand a one foot drop, striking any cask surface, onto a flat horizontal surface.

The analysis is shown in Appendix 2.10.5.

2.6.7 Corner 0 on The specified condition is not applicable since the package weight is greater than 10,000 pounds.

2.6.8 Penetration The impact of a vertical steel 1-1/4 inch diameter, 13 pound cylinder from a height of four feet will not puncture the cask outer steel shell.

In addition, there is no externally mounted equipment on the cask, the damage of which due to this transport condition, would limit the cask structural adequacy or hinder its function.

2.6.9 Comoression This spr.cified condition is not applicable since the package weight is greate? than 10,000 pounds.

Impact at the upper corner of the cask will result in the cask contents pushing against the cask lid. The contents of the cask, it should be noted, are close fitting or shored to limit actual movement. The loading on the cask lid is realized in the studs. The stud stress is therefore equivalent to the inertia load of the contents and the inertia force of the lid itself.
