| 1. Kind of Data stored in DDB | ||
|
Following data are stored in JAEA-DDB. (1) Diffusion coefficient in domestic rocks and its related data. (2) Diffusion coefficient in domestic bentonite and its related data. (3) Diffusion coefficient in foreign bentonite and its related data. | ||
| 2. Solid phase | ||
|
Following solid phases are presently included in the JAEA-DDB (1) Domestic Rocks • Crystalline rock (Acidic or Basic rock) • Sedimentary rock (Sandy, Muddy and Tuffaceous rocks) • etc. (2) Domestic Bentonite • Kunigel-V1 • Kunipia-F • etc. - purified smectite - silica sand mixed sample etc. (3) Foreign Bentonite • MX-80 • Avonlea • etc. | ||
| 3. Elements | ||
|
31 elements are presently included in the JAEA-DDB • Am, Cm, Cs, Nb, Ni, Np, Pb, Pd, Pu, Ra, Se, Sm, Sn, Tc, Th, U, Zr (Major elements for safety assessment.) • Ba, Be, C, Ca, Cl, Co, Fe, H2O, I, K, Mg, Na, OH-, Sr (Other elements) | ||
| 4. Database Contents | ||
|
JAEA-DDB system contains about 60 properties (data and related information) per 1 record (data). JAEA-DDB system contains about 2,000 data of diffusion coefficient. | ||
| 5. Database Systems | ||
| In the JAEA-DDB system, there exists two types of systems ; | ||
|
• JAEA-DDB Web version =>enables you to use directly the database through the web browser. • JAEA-DDB Access 2002 version =>enables you to download and use the database with the Microsoft Access 2002 in Windows computers. | ||
