Tyson Wardle, aged 28 and formerly from Barnsley, was just 12 days away from being released when he threw a bucket containing urine and faeces into a staff office on his wing.
The bucket hit one the officers and Wardle was later charged with common assault following the incident in December.
He was serving time for possession of an offensive weapon when he targeted the prison officers on his wing.
“Together with staff at the prison service we are continuing to eliminate crime inside the prison and bring those involved in such incidents before the courts.”
