According to Sakorof (I know i'm spelling his name wrong), the team of Russian scientist working on the bomb were being guided on the track that lead to success in making it.  The team got curious as to how those above knew what they did.  Seeing that the handlers did not want to expose how they knew such, told the scientist that another team was working on the bomb. 
 
Side note, Sakorof made a better H bomb than we did.

Andrei Sakharov is who you mean. 
https://en.wikipedia.org/wiki/Andrei...uclear_weapons
In mid-1948 he participated in the 
Soviet atomic bomb project under 
Igor Kurchatov and 
Igor Tamm. Sakharov's study group at FIAN in 1948 came up with a second concept in August–September 1948.
[11]  Adding a shell of natural, unenriched uranium around the deuterium  would increase the deuterium concentration at the uranium-deuterium  boundary and the overall yield of the device, because the natural  uranium would capture neutrons and itself fission as part of the  thermonuclear reaction. This idea of a layered fission-fusion-fission  bomb led Sakharov to call it the 
sloika, or layered cake.
[11] The first Soviet atomic device was tested on August 29, 1949. After moving to 
Sarov in 1950, Sakharov played a key role in the development of the first megaton-range Soviet hydrogen bomb using a design known as 
Sakharov's Third Idea in Russia and the 
Teller–Ulam design in the United States. Before his 
Third Idea,  Sakharov tried a "layer cake" of alternating layers of fission and  fusion fuel. The results were disappointing, yielding no more than a  typical fission bomb. However the design was seen to be worth pursuing  because deuterium is abundant and uranium is scarce, and he had no idea  how powerful the US design was. Sakharov realised that in order to cause  the explosion of one side of the fuel to symmetrically compress the  fusion fuel, a mirror could be used to reflect the radiation. The  details had not been officially declassified in Russia when Sakharov was  writing his memoirs, but in the Teller–Ulam design, soft X-rays emitted  by the fission bomb were focused onto a cylinder of lithium deuteride  to compress it symmetrically. This is called 
radiation implosion.  The Teller–Ulam design also had a secondary fission device inside the  fusion cylinder to assist with the compression of the fusion fuel and  generate neutrons to convert some of the lithium to tritium, producing a  mixture of deuterium and tritium.
[12][13] Sakharov's idea was first tested as 
RDS-37 in 1955. A larger variation of the same design which Sakharov worked on was the 50 Mt 
Tsar Bomba of October 1961, which was the most powerful nuclear device ever detonated.

In 1945, the Soviet intelligence obtained rough blueprints of the first U.S. atomic device.
[38][39]  Alexei Kojevnikov has estimated that the primary way in which the  espionage may have sped up the Soviet project was that it allowed  Khariton to avoid dangerous tests to determine the size of the critical  mass.
[40]  These tests in the U.S., known as "tickling the dragon's tail",  consumed a good deal of time and claimed at least two lives; see 
Harry Daghlian and 
Louis Slotin. 
One of the key pieces of information, which Soviet intelligence obtained from 
Fuchs, was a cross-section for 
D-T fusion. This data was available to top Soviet officials roughly three years before it was openly published in the 
Physical Review in 1949. However, this data was not forwarded to 
Vitaly Ginzburg or 
Andrei Sakharov until very late, practically months before publication.[

Sakharov, the Sloika design become a priority,  which resulted in a successful test in 1953. 
In the 1990s, with the declassification of Soviet intelligence  materials, which showed the extent and the type of the information  obtained by the Soviets from US sources, a heated debate ensued in  Russia and abroad as to the relative importance of espionage, as opposed  to the Soviet scientists' own efforts, in the making of the Soviet  bomb. 
The vast majority of scholars[like whom?]  agree that whereas the Soviet atomic project was first and foremost a  product of local expertise and scientific talent, it is clear that  espionage efforts contributed to the project in various ways and most  certainly shortened the time needed to develop the atomic bomb.[

Yet the research for the Soviet analogue of "classical super" continued  until December 1953, when the researchers were reallocated to a new  project working on what later became a true H-bomb design, based on  radiation implosion. This remains an open topic for research, whether  the Soviet intelligence was able to obtain any specific data on  Teller-Ulam design in 1953 or early 1954. Yet, Soviet officials directed  the scientists to work on a new scheme, and the entire process took  less than two years, commencing around January 1954 and producing a  successful test in November 1955. It also took just several months  before the idea of radiation implosion was conceived, and there is no  documented evidence claiming priority. It is also possible that Soviets  were able to obtain a document lost by 
John Wheeler on a train in 1953, which reportedly contained key information about thermonuclear weapon design.
