1.0 INTRODUCTION
BNFL - Fuel Solutions (BFS) has developed the TranStor system for storage l
and transportation of spent nuclear fuel. This system is comprised of four primary ccmponentst 1
A sealed metal canister that provides the structural support and containment j
boundary for spent nuclear fuel during storage A reinforced concrete cask that provides physical protection, shielding, and e
convective cooling for the canister during interim storage and short, onsite movement from the reactor building to the storage pad A shipping cask that provides containment and shielding during transportation of the canister from the storage pad to a centralized storage facility, a final disposal site, or a reprocessing facility A transfer cask that provides shielding during onsite fuel loading and transfer operations into and out of the storage or shipping casks.
An illustration of the shipping cask is provided in Figure 1. The cask consists of inner and outer stainless steel shells separated by a layer oflead gamma shielding.
A layer of polymeric-based neutron shielding is provided outside the outer shell and is encased in a stainless steeljacket. The inner and outer shells are welded to the bottom plate forging and the top closure flange forging. The combination of the inner shell, the top flange forging, the bottom plate, and the closure lid defines the cask cavity and, with closure seals, vent, and test port plugs and seals, defines the cask containment boundary. Four solid steel lifting trunnions are welded to the outer steel shell at 90-degree circumferential intervals. Removable energy-absorbing impact limiters are bolted over each end of the cask to provide protection in the event of a transportation accident. The closure system is fully recessed and protected by the top impact limiter.
The structural evaluation of the TranStor shipping cask design must demonstrate the adequacy of the shipping packaging under both the normal conditions of transport and the hypothetical accident conditions described in the U.S. Code offederal Regulations, Title 10, Part 71 (10 CFR 71) [Ref.1]. These conditions include drop impact events. Therefore, the impact limiters are an essential component of the TranStor system. To demonstrate compliance with

DOCUMENT NO.: IL-TP-001 REVISION NO.: 2 PAGE 6 OF 22 l TITLE: TranStor IMPACT LIMITER TEST PLAN U.S. Nuclear Regulatory Commission requirements, the analytical model [Ref. 2]
for the impact limiters will be validated through scale-model quasi-static and dynamic testing.
. This impact limiter test plan outlines a series of scale-model quasi-static tests and drop tests to be performed at Sandia National Laboratories (SNL), Albuquerque, New Mexico. The static test program will use one-eighth-scale models of individual TranStor impact limiters, or portions of those impact limiters, for controlled-rate quasi-static compressive loading in the SNL Force and Pressure Laboratory. Test fixtures that provide alignment stability between the platens of the testing machine, as well as simulation of the interface between the cask and the impact limiter, will be designed and fabricated by BFS, subject to review and l
approval of test fixture baseplate mounting configuration by SNL. The drop experiments will be based on complete quarter-scale models of the TranStor impact limiters and attachments. The cask model used in the impact limiter drop test program will provide an inertial and dimensional representation of the m hipping cask with payload and simulation of cask features that are TranStor s
important to assessment ofimpact limiter performance.
2.0 TEST OBJECTIVES The major objective of the tests is to verify appropriate representation of the impact limiters in the structural analyses used to calculate impact limiter deformations and deceleration loads experienced by the TranStor shipping cask during the drop conditions specified in Reference 1. Validation of the analytical model will be performed by confirming the quasi-static cmsh properties of the impact limiter through the one-eighth-scale quasi-static cmsh test prograrn and by confinning dynamic response of the impact limiter and attachments through the quarter-scale dynamic test program.

Description of the quasi-static test setup and the generated data e
(force-deflection curves).
Reduced data and findings for all drop test orientations.
The second part of the report will be generated by BFS and will present a l
comparison of the analytical results to the test data in the SNL report.
Specifically, this part of the report will contain:
Summary of the properties for the honeycomb used in both the one-eighth-scale quasi-static models and the one-quarter-scale drop impact limiter models.
Comparison of the quasi-static load-deflection curves to those generated in the analysis. If any model modifications are needed, a discussion of those modifications and a new comparison to the test data will be provided.
Comparison of the analytical results to test findings for drop tests in all orientations.
The report will provide the overall conclusions about adequacy of the impact limiter design based on the criteria outlined in Section 3.4.
