environmental equipment qualification; high energy line breaks

Sažetak
The purpose of environmental equipment qualification (EQ) is to demonstrate the capability of safety-related equipment to perform its safety function in aged conditions and under extreme conditions after design bases event (DBE). Equipment qualification is one of the steps in licensing process according to the US regulatory documents and standards ([1] to [3]). This paper discusses the results of calculations performed on the basis of Task 1 and Task 2 reports ([7] and [8]) to determine temperature, pressure, humidity and radiation levels in the Armenian NPP (ANPP) rooms where safety related equipment is situated. In particular, assessment of environmental conditions covers spectrum of high energy line breaks (HELBs) including DBE of 100 mm LOCA on cold and hot leg and in the steam part of the pressurizer, Main Steam Line Break (MSLB), Main Feedwater Line Break (MFW), Make-Up water pipe Break (MUB), Steam Generator Tube Rupture (SGTR) accident, enveloping also primary collector break in the SG, and instrument line 18 mm diameter break in the compartment A004. In principle, detailed calculations of environmental thermal hydraulic parameters were performed only for these rooms in which a break of the observed lines can occur and adjacent areas.
