Abstract

Palivový systém podle vynálezu sestává z hlavové cásti (1) a koncové cásti (2), které jsou spojené vodicími pruchody (3) procházejícími bunkami (4) vymezovacích mrízek (5). Vodicí pruchody (3) jsou pevne spojené s alespon koncovými vymezovacími mrízkami (5). Výska h vymezovacích mrízek (5) a tloustka .delta. sten bunek (4) jsou zvoleny tak, ze jejich numerické hodnoty splnují matematicky a experimentálne stanovenou podmínku. Vynález umoznuje zvýsit tuhost sestavy v prícném a podélném ohybu, zvýsit úhlovou tuhost dvojic vodicí pruchod (3) - bunka (4) vymezovací mrízky (5), snízit ohyb palivovésestavy v její vlastní rovine mezi vymezovacími mrízkami (5) a volný ohyb palivové sestavy v nehomogenních neutronových a teplotních polích pomocí snízené tendence slitiny E635 k radiacnímu rustu. Palivový systém dle vynálezu se vyuzije zejména pro konstrukci pevného rámu.
