Repeated reports giving comparative status of production can keep a potential onemy informed of our over-all effort in the production line. Other plecemal information on quantitative production figures can thereby be better Integrated for the purpose of estimating our over-all production and stockpile of waapons to any given time. 4e “Reactor Covelopment,"* Pare 13. Seoond paragraph outlining the four reactors conprising the core of cur progran gives an excellent lead to any competing nation on what we consider the priority of the many tasks in the field of reactor development.
