The Massachusetts Institute of Technology administration last week chose the only two non-radical nominees as student representatives to the school's Ad Hoc Committee on International Institutional commitments, Phillip Moore, one of the rejected nominees, said yesterday.

The temporary committee, reviews and advises MIT on prospective commitments to other countries.

The committee is a continuation of one formed last year in reply to student concern over MIT's nuclear engineering program in Iran, Constantine Simonides, vice president of MIT, said yesterday.

Graduate students and undergraduates each nominated three students. Then Jerome B. Wiesner, president of MIT, and Simonides, picked one student to represent each group.

Moore said two of the three nominees in both groups had criticized MIT's proposed program for training engineers in Taiwan, and were also members of the Social Action Coordinating Committee, a group which opposed the Iranian nuclear engineering program last spring.

Simonides said he had been unaware that all the rejected nominees were members of the social action committee.
