WASHINGTON (AP) _ Nancy Reagan will visit Boys Town in Omaha, Neb., and receive the ''Father Flanagan Award for Service'' as part of the organization's celebration of its founders' 100th birthday, Mrs. Reagan's office announced Thursday.

Mrs. Reagan is scheduled to address about 600 residents on Nov. 25, and then attend a luncheon with Boys Town staff members, civic leaders and donors to the organization, said Mrs. Reagan's press secretary Elaine Crispen.

Edward Joseph Flanagan, who founded Boys Town in 1917, was born July 13, 1886.

The award, which has been given in the past to such individuals as Jonas Salk, Mother Teresa and Bob Hope, is being given to Mrs. Reagan in recognition of her anti-drug abuse work, Mrs. Crispen said.
