A method and apparatus for treating radioactive waste water containing contaminating ions, colloids and suspended solids having like (usually negative) charges preventing their precipitation. An electric current is passed through the waste water in an EC assembly to cause electro-coagulation of the contaminants and anodes of this assembly are made of a metal that dissolves to provide cations for neutralizing the negative charges and forming precipitates containing neutralized contaminants. Precipitates are then separated from waste water by an electro-magnetic or other filtering unit. The water pH and conductivity may be adjusted before the EC assembly and additives may be introduced into its effluent for enlargement of precipitate particles, improvement of filtration, improvement of dewaterability, and / or enhancement of magnetism.

A method of determining whether an improved item has a better mean lifetime than an existing item having a fully specified lifetime distribution function. A finite number n of examples of the new item are placed on life test, and the failure times of the n examples of the new item are recorded as they occur. At each occurrence of failure, the newly noted failure time is entered into a list of previously noted failure times and the most up-to-date statistical P-value is calculated for the life test so far. When the statistical P-value is sufficiently small there is statistical inference that the new item is better than the current one, and the test is ended.
