Thanks having ddl and data makes this a lot easier to deal with. I think you want something like this.
;with MyNewAverage as
(
select Action, Duration, Curr_date, DATEPART(hour, Curr_date) as HourOfDay, AVG(Duration)/1000 as Avg_Duration
from table_1
group by Action, Duration, Curr_date, DATEPART(hour, Curr_date)
)
SELECT HourOfDay, Action, sum(Avg_Duration), (SELECT sum(AVG_Duration) FROM MyNewAverage where DATEPART(hour, cast(Curr_date as datetime)) = m.HourOfDay) as SummedAverage
FROM MyNewAverage m
group by HourOfDay, Action
order by HourOfDay, Action
