  * There are 3 ways to the operation in the newt week;
   * Leak location will be found and fixed without vent. -> ETMX gate valve will open, no delay.
   * Leak location will be found and not fixed without vent. -> Vent on Wednesday and Thursday, fix leak on Friday, pump down on Friday. -> ETMX gate valve will open, delay for several days.
   * Leak location will not be found and not fixed. -> ETMX gate valve will not open, no delay, but it will be difficult to find beam at ETMX.
