The international thermonuclear experimental reactor (ITER) project aims to
 build a tokamak fusion test reactor to verify the feasibility of fusion
 reactors. The test blanket module (TBM) is the key component of the
 international thermonuclear experimental reactor. The fusion design study
 team proposed the concept of the dual-functional lithium-lead test blanket
 module (DFLL-TBM). The integral severe accident analysis (ISAA) is a
 self-developed ISAA code that models the progression of severe accidents in
 nuclear power plants. A broad spectrum of severe accident phenomena
 including fission product release and transport behavior is modeled in ISAA.
 In this paper, a new version of ISAA, referred to as ISAA-DFLL is
 introduced for the application of DFLL-TBM test blanket module into the
 treatment of multi fluids and the modules of the new physical property and
 heat transfer. The modification is verified by comparing the steady-state
 temperature distribution of the DFLL-TBM first wall with the design
 parameters. Then accident analysis of In-vessel loss of helium coolant in
 first wall and TBM pipe is conducted by using the ISAA-DFLL code. By
 comparing the calculation results with the general safety requirements for
 TBM, it is concluded that the design of the DFLL-TBM system and the
 modifications of the current version are reasonable and accurate.
