Une trentaine de pays d\u00e9pendent partiellement de l\u2019\u00e9nergie nucl\u00e9aire pour leur production d\u2019\u00e9lectricit\u00e9, parmi lesquels les \u00c9tats-Unis, la France ou encore le Japon. En France, l\u2019\u00e9nergie nucl\u00e9aire repr\u00e9sente une part importante de la production \u00e9lectrique nationale.<\/p>\n
Les centrales nucl\u00e9aires utilisent des circuits de refroidissement aliment\u00e9s par des cours d\u2019eau ou des prises d\u2019eau en mer. Ces infrastructures hydrauliques comprennent des canalisations, des galeries d\u2019amen\u00e9e d\u2019eau et des bassins qui doivent faire l\u2019objet d\u2019inspections r\u00e9guli\u00e8res afin de garantir leur bon fonctionnement et leur s\u00e9curit\u00e9.<\/p>\n
Gr\u00e2ce \u00e0 leurs dimensions compactes et \u00e0 leur grande maniabilit\u00e9, les mini-ROV Subsea Tech permettent d\u2019inspecter des zones confin\u00e9es ou difficiles d\u2019acc\u00e8s au sein des circuits de refroidissement et des installations nucl\u00e9aires.<\/p>\n
La portabilit\u00e9, la simplicit\u00e9 de mise en \u0153uvre et l\u2019autonomie \u00e9nerg\u00e9tique de ces syst\u00e8mes offrent une grande flexibilit\u00e9 dans la planification et la r\u00e9alisation des inspections. Les ROV peuvent \u00eatre facilement transport\u00e9s d\u2019un site \u00e0 un autre et d\u00e9ploy\u00e9s par un op\u00e9rateur unique.<\/p>\n

Les circuits de refroidissement des centrales nucl\u00e9aires comprennent des prises d\u2019eau, des canalisations et des galeries hydrauliques permettant l\u2019alimentation en eau des installations.<\/p>\n
Ces infrastructures doivent \u00eatre inspect\u00e9es r\u00e9guli\u00e8rement afin de v\u00e9rifier leur int\u00e9grit\u00e9, d\u00e9tecter d\u2019\u00e9ventuels d\u00e9p\u00f4ts ou obstructions et garantir le bon fonctionnement du syst\u00e8me de refroidissement.<\/p>\n
