President Reagan last Friday nominated Craig C. Black, director of the Los Angeles County Museum of Natural History, to membership in the National Science Foundation. Black, an Amherst graduate, would succeed David V. Ragone.

Reagan renominated Roger A. Yurchuck, a Harvard law school graduate, as a director of the Securities Investor Protection Corporation, for a new term that expires at the end of 1987.

Dennis Miles Kass, a New York investment banker, was nominated to be an assistant secretary of labor.

Reagan also named seven people to recess appointments, meaning they can serve without Senate confirmation. Vance L. Clark was named to succeed Charles Wilson Shuman as administrator of the Farmers Home Administration. Thomas John Josefiak, an attorney with offices in Cincinnati and Columbus, was named to succeed Frank P. Reiche on the Federal Election Commission.

Raymond D. Lett was given a recess appointment to be assistant secretary of agriculture, and Hugh Montgomery was named as alternate U.S. representative for special political affairs at the United Nations. Herbert Stuart Okun was named deputy U.S. representative to the United Nations. Both titles carry the rank and status of ambassador.

Robert E. Rader Jr. and John R. Wall received recess appointments to the Occupational Safety and Health Review Commission.
