Dear Dr. "attson:
An article which appeared in the Manchester Guardian, October 25, 1979, by *:. Ehoja Etemad, who is supposed to be a nuclear engineer and expert in twoyhase flow in France, and who is an authority, it is alleged, on 'lestinghouse design PWRs, alleges that as a rescit of the Three Mile Island Acciden t (possibly) " plant af ter plant is now being re-equipprd with a more powerful safety injection system. "
Is it true that after TMI occurred, that is, after March 28,1979, the safety injection-systems are being changed to provide for a more powerfal emergency coolant injection, which injects coolant at a greater rate of flow or with a greater reservoir of coolant, or both or whatever?
I would like to know whether the emergency core cooling systems for P!Rs*have been changed in any way after the TMI accident occurred and what are the changes, if any, and what are the scientific and technical reasons and analytical basis for such changes and have a copy of the pertinent appr5pria*H reports related to such changes.
Sincerely yours, PW' *!"Y
