1.Scope: The Stress analysis is carried out for the main steam line from Boiler PR-0191 up to the branch point in the existing steam header. The isometrics of following lines have been considered for the analysis. 300-STHH-483040

Main steam line from Boiler PR 0191

100-STHH-483042

Line from main steam to deaeration( up tocontrol valve PV 483275)

100-STHH-483044

Bypass of PV-483275

250-STMH-483059 Down stream of control valve PV-483275 150-STMH-483117 Down stream of control valve PV-483275 100-STHH-483126

Line from main steam line to PV 483324 Silencer

250-STHH-483041

Line from main steam line to PV 483273 Silencer

2.Design Basis 2.1 2.2 2.3 2.4

The input file is based on the Piping Isometrics The pressure, temperature and material are from Piping Isometrics The pipe stress analysis is according to ASME B31.1 The software of stress analysis is CAESAR II Version 5.0

3.Load Cases considered CASE 1 (HYD) WW+HP+H Hydro CASE 2 (OPE) W+D1+T1+P1+H

The whole system is at 515°C except The down stream of PV483273&UV483324 at ambient The down stream of control valve PV483275 at 336°C

CASE 3 (OPE) W+D2+T2+P1+H The The The The

main steam line from boiler to the Battery limit XV is at 515°C down stream of XV is at ambient. down stream of UV483324 is at ambient down stream of PV483275 is at 336°C

CASE 4 (OPE) W+D3+T3+P1+H The main steam line from boiler to the battery limit XV is at 515°C The down stream of XV is at ambient. The down stream of PV483275 is at 336°C
