I. General Introduction to WRENDA
The nuclear data request lists for fission-reactors, fusionreactors
and nuclear-safeguards development appear in Parts II,
III and IV, respectively, of this document. Supporting information
which is pertinent to only one of the request lists has been
collected in sections immediately preceding the relevant request
list. Information applicable to all the request lists appears in
Part I. Expansions of codes used in the request lists can be found
in the appendices at the end of the document.

Background and General Information
The use of a "request list" for communication of the
data requirements of a developing technology to the producers
of the required data is long standing in both the
United States and the United Kingdom. In 1968,' the Neutron
Data Compilation Centre at Saclay initiated publication of
a request list for neutron data measurements from a computerized
file, known as RENDA, on behalf of the European-
American Nuclear Data Committee (EANDC). The list contained
requests from the countries represented on that committee.
In 1971, the International Nuclear Data Committee (INDC)
recommended that the IAEA assume responsibility for publication
of an expanded international data request list,
which would include neutron data requests from a larger
number of countries and international organizations.
The data request file maintained by the Nuclear Data
Section of the IAEA is known as WRENDA. The input to this data
