[en] This paper presents an overview of the procedures used at the Argonne National Laboratory (ANL) to review Safety Analysis Reports for Packagings (SARPs) submitted to the US Department of Energy (DOE) for issuance of a Certificate of Compliance. Prior to certification and shipment of a packaging for the transport of radioactive materials, a SARP must be prepared describing the design, contents, analyses, testing, and safety features of the packaging. The SARP must be reviewed to ensure that the specific packaging meets all DOE orders and federal regulations for safe transport. The ANL SARP review group provides an independent review and evaluation function for the DOE to ensure that the packaging meets all the prescribed requirements. This review involves many disciplines and includes evaluating the general information, drawings, construction details, operating procedures, maintenance and test programs, and the quality assurance plan for compliance with requirements. 14 refs., 6 figs

[en] A method for the preparation of notched bar impact bending test pieces is proposed where the test pieces are not subject to uncontrolled heat treatment which might alter the true notch value. (RW)

[en] Very high pressure and acceleration is necessary to launch flier plates to hypervelocities. In addition, the high pressure loading must be uniform, structured, and shockless, i.e., time-dependent to prevent the flier plate from either fracturing or melting. In this paper, a novel technique is described which allows the use of megabar level loading pressures, and 10⁹ g acceleration to launch intact flier plates to velocities of 12.2 km/s. 32 refs., 2 figs

[en] The public has questioned the severity of the regulatory 9 meter drop onto an unyielding target required for Type B radioactive material shipping packages since this drop height results in an impact velocity of only 13.3 m/s (30 MPH). It is the unyielding nature of the regulatory target which makes the 9 meter drop so severe. In this paper a method for relating higher velocity impacts with yielding targets to impacts onto an unyielding target is developed. The severity of impacts with yielding targets is decreased by the amount of the impact energy absorbed in damaging the target. There have been previous attempts to correlate impacts with yielding targets to lower velocity impacts onto an unyielding target, and this work is an expansion of those efforts

[en] The synthesis of a safety device for restraining and dissipating some of the energy of a whipping pipe is described. The device has similar restraining capabilities in all radial directions and is to surround the pipe which may whip. Devices were tested both statically and dynamically. It was found that the restraint converted an impact load into an impulse of considerably longer duration and relatively constant load. The magnitudes of loads determined in static tests can be used for dynamic design purposes since the loads for a restraint were similar under both static and dynamic conditions. There is a need to develop analytic procedures to determine loads for all sizes of restraint from either information on other sizes, data for individual components, or from the stress-strain behaviour of the material being used.

[en] This paper describes the drop testing of a one-third scale model transport cask system. Two casks were supplied by Transnuclear, Inc. (TN) to demonstrate dual purpose shipping/storage casks. These casks will be used to ship spent fuel from DOEs West Valley demonstration project in New York to the Idaho National Engineering Laboratory (INEL) for long term spent fuel dry storage demonstration. As part of the certification process, one-third scale model tests were performed to obtain experimental data. Two 9-m (30-ft) drop tests were conducted on a mass model of the cask body and scaled balsa and redwood filled impact limiters. In the first test, the cask system was tested in an end-on configuration. In the second test, the system was tested in a slap-down configuration where the axis of the cask was oriented at a 10 degree angle with the horizontal. Slap-down occurs for shallow angle drops where the primary impact at one end of the cask is followed by a secondary impact at the other end. The objectives of the testing program were to (1) obtain deceleration and displacement information for the cask and impact limiter system, (2) obtain dynamic force-displacement data for the impact limiters, (3) verify the integrity of the impact limiter retention system, and (4) examine the crush behavior of the limiters. This paper describes both test results in terms of measured deceleration, post test deformation measurements, and the general structural response of the system

[en] A new unyielding target has been developed at SNL under the direction of the Transportation Technology Center. The target has been constructed at the SNL Sol-Se-Mete cable site and will be used for testing Type B and plutonium air-transportable packages. The target is 10.4 m in length, 4.9 m in width and 7.6 m deep with a mass of >900,000 kg. The steel section is 3.1 m by 8.5 m with an average thickness of approximately 0.2 m
