3. NATURE OF PHYSICAL PROBLEM SOLVED

The programme carries out iterative steam cycle heat balance calculations for a wide variety of steam cycles including single reheat, live steam reheat and multistage moisture separation. Facilities are also available for including the steam-consuming auxiliaries associated with a marine installation.
Though no attempt is made to carry out a detailed turbine blading design the programme is capable of automatically varying the blading efficiency from stage to stage according to local steam volume flow rate, dryness fraction and shaft speed.

8. RELATED AND AUXILIARY PROGRAMS

STEAM-A is a programme for the analysis of single pressure reheat steam cycles only.
A bled steam turbine boiler feed pump drive is assumed and reactor coolant temperatures and boiler pinch points are used as input.
STEAM-B-similar to STEAM-A except that feedwater and steam temperatures are input instead of reactor coolant temperatures and boiler pinch points.
