Dear Dr. Yeh:
Thank you for your recent suggestion to help improve conditions at Three Mile Island Nuclear Station Unit 2.
Your suggestion was one of many which were considered for possible application at the plant.
In addition, the efforts of a very large number of people in the Nuclear Regulatory Commission, the State of Pennsylvania, other Federal and State agencies and industry organizations were applied at the plant.
These efforts were successful in assuring the continued cooling of the reactor core.
On behalf of the entire Nuclear Regulatory Commission staff, I want to expres:,
my appreciation for your interest and contribution.
Sincerely, A
Harold R. Denton, Director Office of Nuclear Reactor Regulation 700 3010,;WF

Dear Sir:
This is to confir that on this date at 2:30 p.m. I sent the following telegram to both your Of fice and the. Nuclear Regulatory Commission in
-Washington, D. C.
Inject Carbon dioxide gas into the reactor t'o react with hydrogen to form methane and water with the diminu tion of volume. The above reaction is practically irreversible below 300*C, and high pressure favors its irrever sibility.
The products are not flammable and can be removed from the rea: tor safety.
s DT. George Yeh Villanova University The above suggestien is based or. the well known reaction:
CH4 + 2H 0 C07 + 4H2 7
there will be the di=inution of gas volume by one volume As =ay be obvious, per :.very four volu es of the hydrogen inside the reactor when the reaction The forward reaction is favored by proceeds in the forward direction.From free-energy data, below 300*C the reac don will high pressure.
Small heat of the reaction almost irreversibly in the forward direction.
may help in maintaining the high pressure which f avors the forward reaction, and therefore should not create any problems as far as the reaction is carried out at a temperature below 600*C, at which temperature the four Carbon dioxide will have the ccepcunds should be in molar equilibrium.
additional effect of retarding the combustion involving hydrogen, as may bs The cethane-water =ixture formed by the above reaction can be cbvious.
readily removed fre the reator safely since it is not fla=mable.
The mixture removed to the outside of the reactor may be separated by cooling into water and nethane, which may be burned with air c-oxygen.
The end products will be carbon dioxide and water both of w'.Ach are radioactive
-and require safe disposal.
