ORO REVIEV OF REPORT ORNL-5408/R1 Safety Analysis for Packaging (SARP) of the Oa

'ge Natic.al Laboratory Garten Carrier No. 2, Revisicn 1 Raymond C. Harris William A. Pryor This review is made under the mquirments of DOB4 0529 and 5201.

Le container is one-of-a-kind arxi is used to transport fissile and large quantitie:s of radioactive materials. These materials will be shipped as solids.

A.

General Standards for All Packaging:

1.

The material and construction are such that there will be no signif-icant chenical, galvanic, or other reacticn among container cmpo-nents or between the package cmpcnents and the package contents.

2.

A thennal shield consisting of solid cmponents covers the package during transport. The effectiveness of the package and its thennal shield would be unaffected under nonral conditions of transport.

3.

'1he reqairencnts for positive closure of the ccntak.ar are fully met.

4.

Lifting devides for packaging:

Three separate systems can be used for lifting the package: (1) Four ears are located symnetrically near the top of the fire shield. The ears are 5/8 x 12-1/2 x 12-1/4-inches and they are attached to the skin of the fire shield by 5/8-inch full-around fillet welds.

A 3-1/4-incti eye is located in each ear for lifting purposes. The material of construction is idmtified on drawing M-12166-CD-043, Rev.

1, as " steel," presunably carbon steel. (2) A 1-1/2-inch-diameter loop, in the form of an inverted "U,"

is located in each corner of the 5 x 5-ft. container-l' ire shield transport skid. The material of ccxwtructicn is designated " mild" steel (see Drawing D-55999, Rev. 6). Each loop is reportedly attached to the skid by a

_)

1/2-inch full-amund fillet weld. (3) Four 2-inch-dianeter lifting trunnims am located cn the ccntainer itself. Each set of trunnions is cmnected by a 3/4-inch-thick 304L stainless steel strap (see Dwg.

M-11332-D4-012).

The top closure plug is designed to be lifted by a 3/4-inch eye located in a lug attached to the top closure plug. The steel lug is 1-inch in thickness and is attached to the skin of the plug by a 3/8-inch full-around fillet weld. A cover is provided to prevent use of the lug for lifting the entire container.

The capabilities of each ccntainer lifting device and of the lifting lug for the top closure plug wem analyzed by ORNL based on mechani-cal pmrties of the materials of ecostructicn shown in Table 2 of the SARP ans on well-recognized analytical techniques. OR review indicates that reascnable basic assurptions are used in the analysis.

Further, OR calculaticns substantiate conclusicos in the SARP that the container and top plug lifting devices meet applicable cbserva-tion that failure of any of the devices would not inpair the ccntairment or shielding properties of the package.

5.

Tiedown devices for packaging:

The container is nonnally shipped bolted to a skid and enclosed in its fire shield. The fire shield is also bolted to the skid. Cables (eight total) are used to tie down the fire shield and the skid to the bed of the transport vehicle. For the sake of analysis, the l

following tiedown cases are ccnsidered in the SARP: (1) the tiedown of the ccntainer to the skid, (2) the tiedown of the fire shield to the skid, and (3) the tiedown of the fire shield to the bed of the transport vehicle. The first two cases involve the use of eight 1-1/2-inch-dianeter steel bolts, respectively. A 45-degree cable angle (as specified in the loading procedure) frun the verticle and use of the lifting ears are assuned for the third case. Mechanice

. properties referenced above am used for all cases. Standard calcula-ticnal techniques are used in the evaluaticos to denonstrate ccmpli-ance of each case with applicable requirements. OR believes that reascnable basic assurptions and calculational techniques have been used in the SARP for evaluating tiedown capabilities. Thus, OR agrees with ORNL that each case meets stress limitaticn requirenents for tiedown devices, when used for tiedown purposes, failure of the fire shield lifting ears under excessive load would obviously impair the ability of the package to meet other requirements of General Standards for All Packaging. However, OR feels that the device meets the intent of this latter requirement.

B.

Stmctural Standards for Ty'pe B and Larce Quantity Packaging Well recognized theory is used in the SARP to demonstrate the capability of 'che ccntainer relative to requirements in the structural standards for Type B and large quantity packaging. OR review indicates that ORNL has adequately covered and adequately dancnstrated in the SARP the ability of the package to meet these requirements.

C.

t W 1 Conditions of Transport Standard techniques and test results related to this container have been used in the SARP to demonstrate ccmpliance of the container with all requirements for nonnal ccnditicns of transport. The OR review substanti-ates the ORNL conclusicn that the container meets these requirenents.

D.

Hypothetical Accident Ccnditions The evaluaticn in the SARP of-the ccntainer to meet requirenents under hypothetical accident conditions is based on standard calculational tech-niques and/or special analytical methods developed by ORNL frun extrapola-ticn of test data related to this ccntainer. Results of the evaluaticn indicate ccmpliance of the ccntainer with all of the subject conditions.

-_-_-_-__a

. he OR review of the SARP and related reference docunents substantiates this ccoclusim. However, ORNL has assuned for part of-the analysis an unusually high specific energy value (100,000 psi) for steel in cmpres-sicn. As used in the SARP, OR believes that this specific energy number should be 60,000 psi. Additionally, scme test data frun drop tests by ORNL has not been interpreted in a ccnservative manner. Therefore, for the following reasms, OR feels that defonnation to the ccntainer frun a 30-foot free drop has been underestimated in the SARP by as much as a factor of about 1.6.

a.

The data for steel shown in Table 2 of the SPEP was obtained frun 30-foot drop tests using solid circular cylindrical specimens with diameter of 1"

x 1"

long (reference 1). Bis value for a large-diameter thin-walled member should be less than values reported in reference 1 for stall-diameter solid test specimens. Further, the data for steel in Table 2 was derived by a least square method. A curve alcog the lower portion of the actual test data inplies a specific energy significantly lower than the 100,000 psi value used in the SARP.

b.

Curves developed by Clark (reference 2) demonstrate the yield stress dependenm on strain rate. A curve for a 30-foot drop (velocity of 44 ft/sec, was interpolated frun Clark's data and was used by ORNL to develop a FORTRAN program for estimation of the respcose of cylindri-cal lead-snielded containers to end impacts (reference 3). The inter-polated curve also implied a specific energy significantly below 100,000 psi. Output frun the FORTRAN program was in reasonable agrement with results obtained frun drop tests by ORNL (references 3 and 4).

c.

The Hanforti Engineering Developnent Laboratory has reported rocm tmperature tensile test data for 304 stainless steel at intennediate and high-strain rates (reference 5). This test data implies a specif-ic energy of about 50,000 psi.

a-

. Based cn the above ccnsideraticns, OR believes that a 30-foot drop of the ccntainer fran any orientaticn would result in a rnaxinun defonnation to the ccntainer body of abcut 3 in. This deformation ccmpares with a value of 1.% in. shown in the SARP. The larger expected deformaticn value does not prevent the container meeting applicable ccntainment and shielding requirements.

E.

Nuclear Criticality Safety 2330, 235U, and Pu The specified mass limits for the fissile isotopes of are less than their respective mininun critical mass under all conditions of moderation. Due to the 9-in.-thick lead shield in the cask plus the spacing provided by the thennal shield, the fissile material is effective-ly isolated interacticnwise. Thus, the package meets cc.riitions for Fissile Class I.

F.

Quality Assurance The quality assurance requirements for fabrication and maintenance were reviewed by the OR Quality & Reliability Division and were found to be generally acceptable.

G.

Distribution The SARP was distributed under TID 4500, UC71.

H.

Conclusion The requirements of DOEM 0529 and 5201 have been met. Therefore, it is reccnmended that the Garden Carrier No. 2 be certified.
