Experience with simplified inelastic analysis of FFTF test assemblies

Description: Included in the more recent design activities for the Fast Flux Test Facility (FFTF) are a series of test assemblies which will contain experiments in the FFTF reactor. Due to high operating temperatures and severe thermal transients, inelastic analysis is generally required to demonstrate structural adequacy. Based upon previous FFTF experience, a number of simplifications have been made to reduce the inelastic analysis effort. Significant time and cost savings have resulted.

Concrete material characterization reinforced concrete tank structure Multi-Function Waste Tank Facility

Description: The purpose of this report is to document the Multi-Function Waste Tank Facility (MWTF) Project position on the concrete mechanical properties needed to perform design/analysis calculations for the MWTF secondary concrete structure. This report provides a position on MWTF concrete properties for the Title 1 and Title 2 calculations. The scope of the report is limited to mechanical properties and does not include the thermophysical properties of concrete needed to perform heat transfer calculati… more

Evaluation of structural issues related to isolation of the 100-KE/100-KW discharge chute

Description: The issue of excessive post-seismic leakage in the discharge chute of the K East and K West fuel storage basins was resolved by designing isolation barriers to maintain basin water levels if the discharge chute should drain. This report addresses the structural issues associated with isolation of the discharge chute. The report demonstrates the structural adequacy of the components associated with chute isolation for normal and seismic loading. Associated issues, such as hardware drop accidents… more

Fuel storage basin seismic analysis

Description: The 105-KE and 105-KW Fuel Storage Basins were constructed more than 35 years ago as repositories for irradiated fuel from the K East and K West Reactors. Currently, the basins contain irradiated fuel from the N Reactor. To continue to use the basins as desired, seismic adequacy in accordance with current US Department of Energy facility requirements must be demonstrated. The 105-KE and 105-KW Basins are reinforced concrete, belowground reservoirs with a 16-ft water depth. The entire water rete… more

Structural safety evaluation of the K Basin railcar and truck applications

Description: There are two rail spurs in the storage/transfer areas of both the K East and K West fuel storage basins. These rail spurs both end at the west edge of the basins. To avoid accidental entry of a railcar into a basin, administrative procedures and rail control hardware have been provided. Based upon a combination of historical documentation and existing adminstrative controls, a maximum credible impact accident was established. Using this design basis accident, the existing rail control hardware… more

Some findings from FFTF piping and component design analyses

Description: A number of questions that have been commonly raised during elevated temperature design of FFTF components and pipelines are identified and discussed. Although the questions do not lend themselves to simple answers, some guidance based on analysis findings is given. Based upon the limited data developed, uniaxial stress relaxation data can give a reasonable pattern of structural creep damage as a function of time. However, the creep damage magnitude may be as much as a factor of two too low. Ot… more

Seismic evaluation of K basin bridge cranes (HOI-320 & HOI-418) and supporting structure

Description: The Safety Class 1 100-K fuel storage basins are vulnerable to impact damage if a bridge crane were to fall during a seismic event. The pupose of this report is to address the adequacy of the K Basin bridge cranes to resist a seismic-induced fall. The approach used to demonstrate adequacy against falling, was to evaluate the crane structural components relative to requirements specified in ASME NOG-1, Rules for Construction of Overhead and Gantry Cranes. Additionally, wheel lift-off and the ade… more

Large-scale sodium-basalt concrete reaction test LSC-1

Description: The energy and hydrogen released from sodium-concrete reactions must be considered the analysis of beyond-design basis accidents for breeder reactors. Consequently, a large-scale sodium-basalt concrete reaction test was completed in the Large Sodium Fire Facility (LSFF) at the Hanford Engineering Development Laboratory (HEDL). 454 kg of sodium at 593{sup 0}C was spilled onto 0.84 m{sup 2} of basalt concrete 0.61 m deep containing two layers of reinforcing steel bar. From the data obtained, it w… more

Concrete structural analysis tools and properties for Hanford site waste tank evaluation

Description: As Hanford Site Contractors address maintenance and future structural demands on nuclear waste tanks built as early as 1943, it is necessary to address their current safety margins and ensure safe margins are maintained. Although the current civil engineering practice has building codes for reinforced concrete design guidelines, the tanks were not constructed to today`s building codes and future demands potentially result in loads and modifications to the tanks that are outside the original des… more
