Narrative:
ATC vectored aircraft on 16L and 16R. I was on course on glide slope from 10;000 ft MSL. Approach control called out traffic for 16L. My two jump seaters identified the traffic and pointed it out to me. The traffic appeared to be lined up for 16L. I monitored traffic while hand flying the ILS. At 9;000 ft MSL I responded to an RA (resolution advisory) by climbing 1;500 fps. Next the RA commanded a level off. I leveled off and evaluated my position on approach. I directed transponder to TA (traffic advisory); since traffic was still in sight by my two jump seaters and me. I announced that we were high on approach and may have to go around. I then configured aircraft for maximum descent angle and returned to glide path by 1;700 ft AGL. Tower cleared us to land. The other aircraft [requested priority handling from ATC] on short final because he had passed within 100 ft of us. I called the tower supervisor who confirmed that TCAS events are a problem on these two runways.
