The bomb designer reportedly died on June 17 at the age of 92.
Klinishov was one of the creators of the first Soviet two-stage RDS-37 thermonuclear bomb.
It was tested on November 22, 1955 at Semipalatinsk training ground by dropping it from a Tu-16 bomber.
RDS-37 was so powerful that shockwaves smashed windows up to 149 miles from the epicentre of the blast, Mediazona reports.
As a top secret bomb designer, Klinishov won the Lenin Prize in 1962.
He later helped develop newer-generation thermonuclear bombs – known as hydrogen bombs or H-bombs.
Klinishov – whose photo was never released by the Soviet authorities – was found dead by his 67-year-old daughter.
A source told Russian state news agency TASS: “Grigorii Klinishov was found dead in an apartment on Kosmodamianska Embankment.
“The nuclear physicist died as a result of taking his own life.
“He left a death note next to his body. In it, the man said goodbye to his relatives.”
The Russian Investigative Committee confirmed a note was found next to the scientist.
“The reasons for the suicide could be the severe illness of the scientist and the death of his wife,” it said.
An investigation is underway pending a decision on whether to open a criminal case into his death, the committee said.
It comes after a pro-Putin deputy was reportedly found buried in the basement of his home after being brutally stabbed to death.
Alexander Kolodich, 58, is the latest high profile Russian to meet a grisly end after a string of mysterious deaths.
The deputy of the Duma of the Khanty-Mansiysk Autonomous Okrug was discovered wrapped in a white sheet covered in rubble.
Officials made the horror find as Vladimir Putin and the rest of the nation celebrated the annual Day of Russia.
Kolodich, a United Russia party member who led the committee on budget, finance and tax policy, sustained multiple fatal stab wounds.
Chilling images showed the bleak basement he was entombed in after news of his shock murder began to circulate.
Reports claim he became embroiled in a violent confrontation with his 39-year-old gardener at his lavish private home in Moscow.
The conflict is then said to have escalated to a knife fight, with Kolodich sustaining several injuries.
According to the Investigative Committee of the Russian Federation, his horrified wife, 55, heard his screams and rushed to help him.
The gardener is alleged to have then plunged the weapon into her several times too, before she managed to escape.
He then allegedly buried Kolodich in the basement of his own home in an attempt to conceal his crime, before fleeing the scene.
Cops arrested the suspect after discovering Kolodich, who avidly supported the war in Ukraine.
