SUBJECT:
THREE MILE ISLAND 2 - STAFF COniACTS WI fH OUTSIDE 0xGANI7.ATIUNS (1) Contact with Dr. M. Haas, Suffalo, NY:
Cn April 1,1979, at the reccmaandation of M.
laylor, Probabilistic Analysis Staf f, RES, I called Dr. Maas, State University of New York, Suffalo~, NY (home phone: [ ~
l office phone 716--331-2826) regarding the potential for hydrogefexplosion in an environment of high humidity.
He discussed minimum hydrogen concentrations for flammability and detonation in-a steam atmosphere at 300 F and 1000 psi.
He suggested the addition of a che:nical to the primary coolant which could aid in reducing the hydrogen concentration.
I had no further contact on this subject with Dr. Haas.

Contact with W. Riehl, NASA; Huntsville, Alabama:
On April 1,1979 at about 3 a.m. I received a call from DOE in
'.lashington D. C. advising that Dr. W. Riehl from NASA in Huntsville, Alabama was enroute to Three Mile Island to assist the staff and the licensee on matters relating to hydrogen explosion and recombination.
Dr. Riehl arrived at about noon.
I discussed with him the status of the hydrogen concentration inside containment and the available methods of hydrogen control.
I arranged for a contact with the licensee.
Dr. Richl had questions regarding the constructica and material for the spark arrestor of the hydrogen recombiner.
Later in the day he joined the task force at the Middletown Armory.
