The reliable information on design and material properties of self-coo
led Li-Li blanket and liquid metal divertor under neutron radiation co
nditions can be obtained using the concept of combined technological a
nd material in-pile tests in a vanadium-lithium loop. The method of in
-pile loop tests includes studies of vanadium-base alloys resistance,
weld resistance under mechanical stress, multipurpose coating formatio
n processes and coatings' resistance under the following conditions: h
igh temperature (600-700 degrees C), lithium velocities up to 10 m/s,
lithium with controlled concentration of impurities and technological
additions, a neutron load of 0.4-0.5 MW/m(2) and level of irradiation
doses up to 5 dpa. The design of such an in-pile loop is considered. T
he experimental data on corrosion and compatibility with lithium, mech
anical properties and welding technology of the vanadium alloys, metho
ds of coatings formation and its radiation tests in lithium environmen
t in the BOR-60 reactor (fast neutron fluence up to 10(26) m(-2), irra
diation temperature range of 500-523 degrees C) are presented and anal
yzed as a basis for such loop development.
