Validation of the numerical tools used for modeling of the fusion plasma is an important step in the interpretation of experimental results. As several codes are usually used in the fusion community to model the same plasma processes, prior verification of the codes should be done in order to avoid discrepancies in the results treatment. Often numerical codes use different post- and pre-processing routines, coordinate system conventions, etc. These make such comparison complicated. One of the main efforts within the Integrated Tokamak Modeling Task Force (ITM TF) project is the verification and validation of the existing numerical tools on the existing tokamak experiments. The framework is developed in ITM that provides common standard interfaces for accessing, storing and exchanging data. All codes integrated in ITM framework use this common interface which makes verification process straightforward. Analysis of the plasma equilibrium and MHD stability is one of the subjects covered by the ITM. Several equilibrium and MHD stability codes are integrated in the ITM framework presently. Initial verification of the fixed-boundary equilibrium codes CHEASE, HELENA, SPIDER was performed using Tore Supra equilibrium reconstructed with EQUAL code. The compared profiles used as input to the MHD stability and transport codes are in agreement. In this work reconstruction of the JET equilibrium will be used for further verification of the equilibrium codes. Equilibrium unstable to the internal or external kink modes will be used for the verification of the MHD stability codes MARS, MARS-F, KINX. ITM tools will be highlighted available in the area of the equilibrium reconstruction and MHD stability analysis.
