spring Nationals 2022- name of pool?

Northside ISD Swim Center8400 N Loop 1604 WSan Antonio, Texas 78249

I believe ISD stands for Independent School District.  The competition pools are outdoors, but there is also an indoor pool that can be used for warmups.  You can see more information if you go to what was published for the cancelled 2020 Nationals at https://www.usms.org/events/national-championships/pool-national-championships/2020-pool-national-championships/2020-spring-national-championship/2020-spring-national-championship-meet-information

That is correct. The competition pool plus dive well and instructional pool which can be used for warmup are outdoors. There is an additional 50m indoor pool for warmup. Full meet information will be published on this page by next week. We plan to open entries by the end of January.  

Is this address the actual pool location? Some swimmers at the last Nationals held there were at another location and missed their  event!!  I am 2-3 times checking this time!

Yes, 8400 N Loop 1604 W, San Antonio, TX 78249 is the correct address for Northside ISD Swim Center. 

THANX   I'll be signing up soon. As long as my creaky right shoulder cooperates!
