Claim 1
Independent Claim
92 words
METHOD FOR THE PURIFICATION OF THE PRIMARY FLUID OF A NUCLEAR REACTOR WHILE OPERATING AND AT POWER WHEREIN SAID FLUID CIRCULATES AND ACCUMULATES IMPURITIES, COMPRISING THE STEPS OF SEPARATING A PORTION OF SAID FLUID FROM ITS CIRCUIT, DISTILLING SAID PORTION AT A TOTAL PRESSURE SUBSTANTIALLY EQUAL TO THE PRESSURE PREVAILING IN THE PRIMARY FLUID CIRCUIT WHEN THE REACTOR IS AT POWER, THEREBY FORMING VAPOR OF SAID PRIMARY FLUID AND RESIDUAL LIQUID CONCENTRATE CONTAINING SAID IMPURITIES, RETURNING SAID VAPOR TO SAID PRIMARY FLUID CIRCUIT AT SAID TOTAL PRESSURE AND DISCARDING SAID LIQUID CONCENTRATE.
