Analysis of Steady-State and Pulsed Operating Regimes for Controlled Thermonuclear Reactors with Very Large Power Ratings.

摘要

The operating regimes of large CTR's are identified and examined for cases of steady-state and pulsed operation. Several technological benefits of these large reactors are determined: (1) low maximum magnetic field strength requirements (25to 50percent less than for 5000MW(th) reactors), (2) high n tau products (10exp 15to 10exp 17sec/cm exp 3 ) with associated high burn-up fractions (10to 50percent), (3) relatively little problem with impurity build-up,and (4) long confinement times (50to 500seconds). The advantages of pulsed operation are also discussed: (1) smaller problem with impurities than in the steady-state case, (2) alleviation of any possible fueling difficulties,and (3) no problem with control of temperature in the pulsed reactor based on a simple control function model incorporating a finite delay time.
