NS 2 was never operational - take that into account. NS 1 was only supplying about 20% of capacity at time of explosion. NS1 has capacity of 59 billion cubic meters. The Poland pipeline can carry 33 billion cubic meters, Ukraine has 2 Russian pipelines that run through them that supply different parts of Europe - they account for about 16% of all of Europe's natural gas imports (when in operation) - I could not find an exact volume for those quickly but it's a lot.
