Point value redistributed to the 2 answers equally.

Disagree to baron sample as this applies to "before use of hydraulic system" not for hydraulic fluid additions.

Facility comment on question / answer 4.05:

For the second part of the answer, both the TCN and TCN-2 go through the same review cycle. The real difference is that the TCN-2 may be implemented prior to obtaining the SRO, NRC, and Site Ops Director signatures.

Reference 4000-ADM-3000.01 Step 4.3.4.2 and 4.3.4.1 2 (Both are approved in accordance with 4000-ADM-1218.02 section 4.6.6 but the TCN-2 has 14 days after implementation for the above signatures.)

Examiner resolution:

Agree, the answer will be changed to : A TCN may change the intent of a procedure (and a TCN-2 may not) and has to complete the full review, concurrence and approval requirements prior to implementation.

A TCN-2 requires fewer (usually 4) signatures prior to implementation and has 14 days to complete review and approval requirements.

Facility comment on question / answer 4.08:

For answer b, the word " implementation" should be also allowed in

place of Responsible Supervisor's signature because his signature implements the UWI.

Reference 4000-ADM-3000.01 Step 4.5.2 and 4.5.2.2.
