Serbian title

Nuklearne elektrane — Instrumentacijski i upravljački sistemi značajni za bezbednost — Ispitivanje u svrhu nadzora

English title

Nuclear power plants - Instrumentation and control systems important to safety - Surveillance testing

Serbian scope

U ovom standardu izloženi su principi za ispitivanje instrumentacijskih i upravljačkih sistema koji, prema standardu IEC 61226, obavljaju funkcije tipa A, B i C u toku uobičajenog rada elektrane i kada je ona isključena, kako bi se proverila raspoloživost navedenih funkcija posebno u pogledu otkrivanja grešaka koje mogu da onemoguće ispravno obavljanje funkcija koje su značajne za bezbednost. Ovaj standard obuhvata mogućnost ispitivanja u kratkim intervalima ili neprekidnan nadzor, kao i periodična ispitivanja u dužim intervalima. Njime se takođe uspostavljaju osnovna pravila koja se odnose na konstrukciju i primenu ispitne opreme i njenog interfejsa sa sistemom koji je značajan za bezbednost.

English scope

Lays down principles for testing I&C systems performing category A, B and C functions, per IEC 61226, during normal power operation and shutdown, so as to check the functional availability especially with regard to the detection of faults that could prevent the proper operation of the functions important to safety. Covers the possibility of testing at short intervals or continuous surveillance, as well as periodic testing at longer intervals. It also establishes basic rules for the design and application of the test equipment and its interface with the systems important to safety. The main change with respect to the previous edition includes an extension of the scope to cover all systems important to safety, and a requirement gradation for systems and equipment performing category A, B and C functions.
