\section{Experiments}

- U5 thermal: Kornilov, Pronyaev
- U5 other energies: Kornilov, Pronyaev
- Cf252 sf : Pronyaev
- Pu239, all energies: Neudecker + Chatillon
- U233: Pronyaev, Vorobyev
- U238: Oberstedt, Saxena
- Th232: Saxena, Oberstedt

\subsection{List of all experiments}
a. U235: thermal (6 data sets)
b. Cf252sf: 
c. U235: all other energies
d. Pu239: thermal, up to 3.5 MeV + Chatillon Einc=1--60 MeV
e. U233: thermal, 0.5 MeV
f. U238: all energies
g. Th232: all energies
h. Minor Actinides: EXFOR data list (Otsuka)

\subsection{Uncertainty analysis of existing data for important actinides}

\subsection{Guideline on uncertainty quantification}

\subsection{Overview of ongoing or planned experiments}
Chi-Nu (LANSCE), U238 (Bruyeres-le-Chatel;BARC,India;IRMM?),
Cf252sf (Eout>8 MeV; Ohio U.);
Cf252sf (IRMM, Chi-Nu?)

\subsection{Overview of ongoing or planned experiments}

\section{Modelling}

Capote, Kornilov, Ohsawa, Schmidt, Serot, Shu, talou, Tudora, Vogt

To be covered in each model section:
physics assumptions, input data \& model parameters, output data, sensitivity of calculated results
to input data and model parameters. Calculations of selected spectra (Cf252sf, U235th, Pu239th).

\subsection{Los Alamos model}
Ohsawa/Talou

\subsection{PbP Los Alamos model}
Tudora

\subsection{Empirical parameterization}
Kornilov/Capote - Two-Watt 

\subsection{Semi-empirical parameterization}
Shu

%\subsection{Monte Carlo models}
%\subsubsection{CGMF} Talou
%\subsubsection{FIFRELIN} Serot
%\subsubsection{FREYA} Vogt
%\subsubsection{FINE} Kornilov
%\subsubsection{GEF}  Schmidt

\section{Evaluations (spectrum + covariances)}

\subsection{Evaluation methodologies}

\subsection{Description of new evaluations}

\section{Data testing}

\subsection{Thermal criticality benchmarks}
Trkov, Capote
+ those calculating the optional thermal benchmarks

It is recommended to add HEU-SOL-THERM-009 serie (A. Trkov) and
PU-SOL-THERM 001 serie (SG34) to the testing.
These are large leakage thermal benchmarks highly sensitive to the thermal U235 and Pu239 spectra.

\subsection{Fast criticality benchmarks}

Kodeli, Morillon, Manturov, Serot

\subsection{$\beta_{\rm eff}$  benchmarks}
Kodeli

\subsection{Reaction rates in reference neutron fields}
Capote and Trkov

\subsection{NUEX experiment}
