Foreword

October 16-18, 2007, the workshop NEMEA-4 was held at the Kaiserstein Palace in
Prague, Czech Republic. The fourth edition of this workshop on Neutron
Measurements, Evaluations and Applications was organised on behalf of the
European coordination action CANDIDE by the Institute for Reference Materials of
the Joint Research Centre with support of the Nuclear Physics Institute of the
Academy of Sciences of the Czech Republic (ASCR). CANDIDE is the Coordination
Action for Nuclear Data for Industrial Development in Europe that focusses at
establishing nuclear data needs from an industry point of view for the near and
midterm future. It has a strong networking component to mobilise researchers to
address those needs. As such, the workshops NEMEA-4 and its planned sequel
NEMEA-5 are important vehicles of CANDIDE networking activities. In particular,
NEMEA-4 addressed the topic of data needs, while NEMEA-5 will consider the state-
of-the-art in nuclear data production methods.
NEMEA-4 carried as a subtitle "Nuclear data needs for Generation-IV and
accelerator driven system". In this context an important contribution to the workshop
was made by Subgroup 26 of the Nuclear Energy Agency of the Organisation for
Economic Cooperation and Development. This subgroup, which addresses sensitivity
studies to establish nuclear data requirements for design and performance studies of
advanced reactors, completed its activities with a set of presentations at the
workshop and a subsequent progress meeting. This valuable contribution to
NEMEA -4 and the CANDIDE project was made possible by the efforts of the
subgroup coordinator M. Salvatores who also participated in the program advisory
committee. A short session on other applications pointed to interests in nuclear data
of the fusion and the medical communities. A large number of researchers from the
nuclear data producing community took note of the data needs emerging from these
sensitivity studies and presented their efforts and commitments in the domains of
nuclear data measurement, evaluation and validation.
The NEMEA series of workshops were initiated as an enlargement initiative of
the Joint Research Centre. They have been organised in Candidate Countries and
New Member States of the European Union and facilitated attendance of scientists
from these new parts of the EU. Also on this occasion the enlargement aspect was
important, as witnessed by the venue of and attendance to the workshop and by the
excellent overview of activities presented by the Czech colleagues from Rez. This
time the main support for this aspect, duly acknowledged, is from CANDIDE and the
ensuing sponsorship of the Research Directorate General of the European
Commission.
I would hereby like to express my gratitude to the local organisers of the
Nuclear Physics Institute of the ASCR. The team of P. Bem and J. Dobes provided
us with excellent provisions that made the workshop a pleasant and successful
event. I furthermore acknowledge the support of the program advisory committee,
H. Aït Abderrahim of SCK-CEN, Belgium, J. Blomgren of the University of Uppsala,
Sweden, R. Jacqmin of CEA, France, A. Koning of NRG, The Netherlands,
D.N. Carpentier of EDF, France, R.W. Mills of Nexia Solutions, UK, M. Salvatores of
CEA, France, FZK, Germany and ANL, USA, and J. Dobes of NPI ASCR, Czech
Republic and the organisational support of C. Cabanillas Platero, I. Celen,
E. Kubrychtová and S. Lehto.
