Andrei Sakharov, the Nobel laureate and human rights activist, was reprimanded yesterday by the Soviet Academy of Sciences for scuffling with police at the trial of a dissident friend in May.

Sakharov and his wife were fined a total of 90 rubles - $131 - by a Moscow court after the shoving match with guards who refused him access to the trial of Yuri Orlov.

He said in a telephone interview with Western reporters that the academy's chief secretary, Georgy Scriabin, said the leadership of the academy had voted to reprimand him for "impermissible" conduct that undermined the prestige of his fellow scientists.

Scriabin told him that his only authority and status in the Soviet Union were based on membership in the prestigious academy, Sakharov added.

"I replied, 'So throw me out of the academy if you consider that necessary and possible,'" he told reporters.

Meanwhile Anatoly Scharansky was sent to a maximum security prison to begin serving his 13-year sentence on treason charges, dissident sources said.

Scharansky's mother, 70-year-old Ida Milgrom, went to Moscow's Lefortovo Prison to deliver books and clothing to her son, but was told he had left at dawn for Vladimir Prison, a czarist-era penitentiary 120 miles northeast of the capital, the sources said.

Scharansky, 30, was convicted of treason last Friday by a Soviet court in connection with his dissident activities. The official Communist Party newspaper Pravda called him a "criminal" yesterday and accused the West of violating the Helsinki accords with its "hullabaloo" over the trial.

In the northern Ukraine town of Gorodnya, the prosecution called for the maximum 15-year sentence for another dissident accused of anti-Soviet activity, dissident sources reported.

The defendant, Lev Lukyanenko, 50 helped found a Ukranian Helsinki group modeled after the Scharansky effort to monitor Soviet observane of the Helsinki accords' human rights provisions.
