Introduction In the thermal analysis for radioactive transport casks, it has become possible to perform them in detail by computer programs, such as TRUMP3(I), HEATING5<2>, HEATING6<3), NASTRANW, ABAQUS'*, TOPAZ2D" and TOPAZ3D". Availability of these computer programs, makes it possible to accurately solve large numbers of problems involving a wide variety of material data provided that accurate input data are used. The thermal properties of the materials, including density, thermal conductivity (temperature dependent data), specific heat (temperature dependent data), phase change or solid-state transition temperature and latent heat should be known as accurately as possible. Some of these properties are difficult to measure. In paticular, heat conduction may vary from data to data depending on test methods. Therefore, when they are used in calculations, the possible in accuracy of variability of thermal data should be accounted for to properly interpret the results. For this reason, Lawrence Livermore National Laboratory (LLNL) has made an effort to collect thermal data and makes it available in a form convenient for handling by computer. More than 1000 material data'8' have been compiled,. Using this data library, a data library processing program THERMLIB(9)(10) for thermal analysis has been developed. The THERMLIB is one computer program of CASKET1""06' code system for thermal and structural analysis of radioactive material transport and/or strage casks as shown in Fig. 1.1. Main features of the computer program THERMLIB are as follows; (1) data have been tabulated against temperature, (2) more than 1000 material data are available, (3) it is capable of graphical representations for structural data and (4) not only main frame computers but also work stations (OS UNIX) and personal computers (OS Windows 3.1) are available for use of THERMLIB. In the paper, brief illustration of data library is presented in the first section. The second section presents descriptions of structural data. The third section provides an user's guide for THERMLIB. - 1 - ID Shock Puncture Fin impact absorber ID Truck Rocking analysis analysis analysis impact analysis 0) OQ 03 CO S T3 ft> A -' 73 I S / O C- I i 1 O (J) c CD rr Co" rt> H o o o O 3 OQ D u 3 C O (0 c en z z I O r+ o o c O o H _ O ? ^ c Z O Rl Rl m rn m z Rl cm ) ) r ) 0) 3 JAERI-Data/Code 98-009 2. Description of Material Property Data The material property data are necessitated for thermal analysis of casks using the computer programs such as TRUMP3, HEATING5, HEATING6, NASTRAN, ABAQUS, TOPAZ and so on. Therfore, a computer program THERMLIB including a material property data library and data processing has been developed. More than 1000 material data have been compiled and are summerized by LLNL. The thermal property data including density, specific heat (temperature depen- dent data), thermal concutivity (temperature dependent data), phase change or solid- state transition temperature and latent heat have been compiled. These data have been collected from over 50 references. The data have been arranged in computer card image and stored in magnetic disks (hard or floppy disks) in a format suitable for computer processing, with the material identified numerically according to a general and flexible classification system. An accompanying numerical index, also in a card image form, describes each material, assigns it an identification number, references the sources of the data by a code number. The CGS-cal-°C(centimeter, gram, second-calorie-degree C) unit system is used for all data. In addition the data are obtained from a source list. The THERMLIB has been written to search the material data list for a specific material identification number. - 3 - JAERI-Data/Code 98-009 3. Material Property Data Library (1) Material property data The computer program THERMLIB has been developed for searching data and plotting data from the data library compiling by LLNL. Thermal property data for over 1000 materials have been compiled and are summerized in the data library. The compilation includes: (a) a numbered list of data sources, (b) a numerical classification system used as a guide in assigning an identifi- cation number, (c) a system of quality indicators used to show the gerneral reliability or accuracy of data, (d) thermal property data for each material collected and estimated by LLNL and converted to a standard unit system, (e) an alphabetical index of materials that includes the identification number assigned to each material and (f) a list of material property data arranged in order of the material identifi- cation numbers and in the format used for input data in the computer program TRUMP. These material property data incude the material identification number and alphanumeric designator, density, specific heat, thermal conductivity, phase-change or transition temparature, the latent heat effect, and tables of specific heat and thermal conductivity versus temperature. (2) Data source The sources for most of the included data in the compilation and several other general sources are listed in abbreviated form in Table 3.1. The numbers of the first column are used in the alphabetical material index to cross-reference the sources. Asterisks indicate the data sources actually used for this compilation. (3) Material classification system The material classification system tabulated in Table 3.2 is used to assign identification numbers to the materials included in the data library. (4) Quality indicator system - 4 - JAERI-Data/Code 98-009 The numerical quality indicators as shown in data sheet columns 73-79 in Table 3.3 may be interpreted approximately as follows: (a) Quality type 0 (or Blank): Data was good or no statement was made in data source restricting its accuracy. No conflicting data was found in any other data sources. (b) Quality type 1: Good data, but specific heat or thermal conductivity was reported only for a limited temperature range. (c) Quality type 2: Either the accuracy of the data was poor or values reported by different sources disagreed. (d) Quality type 3: No data could be found in literature; the LLNL author made an estimate based on theoretical or empirical grounds, or on data for similar materials. (e) Quality type 4: No data could be found in literature; and no accurate estimate could be made.
