Secretary of State George Shultz plans to press human rights issues in new talks with his Soviet counterpart amid signs the Reagan administration has given up hopes of completing a major nuclear arms accord this year.

Shultz, in possibly his last full-scale meeting with Soviet Foreign Minister Eduard Shevardnadze, hopes to "tie down some unresolved issues" in the stalled superpower negotiations to cut long-range nuclear arsenals by 50 percent, Assistant Secretary of State Rozanne L. Ridgway told a congressional panel."We certainly know we can't finish the START (Strategic Arms Reduction Talks) treaty this year," Ridgway said Tuesday.

Shevardnadze is scheduled to arrive here this evening and hold talks with Shultz on Thursday and Friday, Ridgway said. The foreign minister also is expected to call on President Reagan.

Although this week's meetings may be the final major talks between Shultz and Schevardnadze on U.S-Soviet topics, "it certainly does not signal the end of the administration's commitment to press forward" on improving relations, Ridgway said.

"We will press the Soviets to clear the books of the remaining human rights cases . . . we will push on (freer) emigration," Ridgway said. She mentioned exit for members of divided families, separated spouses, dual nationals and people punished for religious or political activity and said "it would appear" the exodus of Soviet Jews may again reach 2,000 monthly, its level of the late 1970s. The August figure was 1,900.
