CDFE is specialized in development of nuclear databases (DB) available through Internet [2]. Some of those
really relational DB are based on the international sources and founds of data produced and maintained
by Nuclear Reaction Data Centres Network and by USA NNDC and NSDD: - ”Nuclear Reaction Database
(EXFOR)”: many data for reactions induced by photons, neutrons, charge particles and heavy ions;
- ”Complete Nuclear Spectroscopy Database ”Relational ENSDF” contains many nuclear spectroscopy
data for all known ( 3200) nuclides from the well-known international fund ENSDF (Evaluated Nuclear
Structure Data File); - ”Nuclear Physics Publications (”NSR” Database)” is the really relational DB
based on the data fund of NSR (Nuclear Science References); - ”Nucleus Ground and Isomeric State
Parameters” combines many useful information on the nucleus as whole and its ground and isomeric states
properties (masses, binding energy, nucleon separation energy, decay mode, energy of various decays, etc).
Those databases used international sources of information but CDFE-developed powerful and flexible
original Search Engines. Other databases are CDFE-produced and maintained: - digital ”Chart of Giant
Dipole Resonance Main Parameters” contains data on main parameters (energy position, amplitude, width,
integrated cross section) of GDR for many nuclei; - digital ”Chart of Nucleus Shape and Size Parameters”
contains data on quadrupole moments, parameters of quadrupole deformation and charge radii for many
nuclei; - ”Calculator and Graph Engine for Atomic nuclei Parameters and Nuclear reactions and Radioactive
Decays Features” gives to one possibility for convenient calculation of: i) nucleus binding energy, ii)
nucleon and nucleus separation energy, iii) decay energy, iv) reaction threshold and energy, v) nucleus
fission parameters; graphical presentation of A-dependencies of data calculated is possible. All databases
maintained by CDFE are widely used for many science research, primarily for investigation of systematical
disagreements between the results of various photonuclear experiments and are the base for education
of MSU Physics Faculty students. The work is partially supported by Russia Grant of Scientific Schools

Migration of EXFOR, CINDA and ENDF nuclear reaction databases to a modern computing environment
[1], including relational databases and multiplatform object oriented languages, allowed to provide full
functionality for database maintenance and improved retrieval capability [2] for external users (via Web
and CD-ROM integrated systems) solving typical tasks of nuclear reaction data services, such as: data
search, retrieval, simple calculations, presentation (formats, tables and plots). Permanent and intensive
growth of IT technologies, especially in Internet, systems of programming, hardware makes possible to
implement such tasks in the nuclear reaction data services with very limited resources, which few years
ago nobody could even imagine. Several such projects are presented in this work. EXFOR data correction
(renormalization) system. Tools for re-calculation absolute values from EXFOR data according to today’s
knowledge (new standards, decay data, abundance). The system has two parts allowing automatic renormalization
using information from EXFOR library and correction factors based on additional information
about experiments and evaluators’ experience collected in the experts knowledge database. New output
from EXFOR Web retrieval system. For advanced users building their applications using modern programming
languages EXFOR retrieval system offers output in XML format. Users developing new methods
