Mr Kelly was one of 38 republican prisoners who escaped the high security facility on 25 September 1983 - the biggest mass breakout in British penal history.
Prison Officer John Adams was shot and wounded by a gunman in the control room before the inmates made their getaway from the H Blocks in a prison food van.
Gerry Kelly, now a Sinn Féin MLA for North Belfast, was charged with firing the shot but was found not guilty.
However a government file from 1983, newly released under the 30 year rule, has named him as the man responsible for the shooting of the prison officer.
Historian Eamon Phoenix said: "The 1983 IRA prison escape dominates the files with a blow-by-blow account of that Sunday in September.
"The main focus of the file is on the role of Gerry Kelly and the files state that prisoner 58 Kelly, as they put it, was responsible for the serious wounding of prison guard Adams.
"It says that prisoner Kelly was seen in the control room of H7 when the escape suddenly erupted wielding a gun so that emerges in these files.
"They are also quite critical of why so many IRA prisoners were allowed to mill around in a central area on a Sunday afternoon and also why a prison food van, which was used as the escape vehicle, was not checked as it passed through various internal gates."
Gerry Kelly spoke to UTV about the incident earlier this year as he released his book The Escape giving his version of events - but he did not reveal who fired the gun.
"I chose not to say anything more about it," Mr Kelly said.
"I accept that there was a number of people in the circle and clearly one of the prisoners shot the prison officer. I was charged with it and found not guilty and that is where I leave it."
Thousands of previously confidential papers from 1983 and 1984 are being released by the Public Records Office part of the 30-year rule. They will be available on the PRONI website.
