Abstract: Verification and validation of lattice code ROBIN-1.7 is performed by using international public benchmark problems, which include critical experiments data, depletion benchmark problems of OECD NEA and other neutron transport-depletion calculations with MCNP code. The result（reactivity, pin power distribution, isotope concentration） shows that independent modules of ROBIN-1.7 such as resonance treatment module, neutron transport module and depletion module are developed and integrated correctly. It is also demonstrated that ROBIN-1.7 has reached the industry level for PWR application.
