Help, im try to make one work in the RITM-200 reactor series, but cant find some informartion... any tip?

Can you be a little more specific please? Are you wanting to model it using a software package like MCNP, or are you wanting to drive a robot into a reactor to check on something? The more details you can give us, the better we will be able to try to help you.

If the RITM-200 fuel assembly is similar to or a modification of the KLT-40 fuel assembly, then it is likely a hexagonal, or triangular, lattice.

This document shows some details of a RITM fuel assembly.
https://iopscience.iop.org/article/10.1088/1757-899X/1019/1/012057/pdf

The core contains 199 fuel assemblies. According to [1] the structure of the fuel assembly remained the
same as in KLT-40S reactor. Each assembly has 69 fuel rods, 9 burnable type-one absorber rods and 6
type-two absorber rods, and 7 control rods in the center of the fuel assembly (Figure 2).

Structurally, the fuel rod is a smooth rod with a diameter of 6.8 mm with a length of the fuel
containing part of 1200 mm. Chromium-nickel alloy 42HNM (41% Cr, 0.2% Mn, 0.2% Mo, 56.1% Ni,
etc.) is used as fuel cladding, because it has a higher corrosion resistance and resistance to disruption of
the water chemistry regime than the traditional zirconium alloy E110. The thickness of the cladding is
0.5 mm. Inside the cladding, there is a dispersed fuel composition consisting of uranium dioxide granules
with low porosity and a silumin (87% Al, 11% Si, 2% Ni). The volume fraction of uranium-containing
material in the fuel pellet is 66%.

Wow
Thanks!!
Wanna make one neutronic analyse, so all that information will be usefull

sure
apologise for my poor english, im trying to make one MCNP analyse in the reactor so any information about: Configuration of FA's (x, y and z), Axial positions of the spacer grids, Dimensions of the FA’s, Pass water between the rods ?, Enrichment and composition, Clading (composition) – E-110, Number of Fuel Rods
Number of Burnable Poison Sticks – VQ avaible will be apreciate
