CPS No. 2000.91 l 1.0' PURPOSE L
Provide for post-modification testing of the Emergency Reserve Auxiliary Transformer (ERAT), 0AP03E and 138KV y
i Circuit Switcher (CS B018), OAP095E, for work performed under plant modification AP-040. This procedure does not include the Transformer Fire Protection deluge. nozzles discharge test, which will be performed as a separate procedure.
2.0- DISCUSSION / DEFINITIONS 2.1 Discussion 2.1.1 Modification Package AP-40 will install the new Emergency Reserve Auxiliary Transformer (ERAT) and Load Tap Changer (LTC).' Major components of this modification include the new ERAT transformer foundation, the new ERAT oil spill retention system, a new 138KV switcher. foundation, relocation of the existing circuit switcher (CS B018), 1AP095E, installation of new 4000 ampere overhead non-segregated bus duct, and associated foundations, a new-fire protection system, a.new grounding grid and additional area-lighting. The new transformer will be installed in the area southwest of the existing transformer. Installation of the new transformer-results from the degraded supply voltage occurrences experienced recently at Clinton Power Station. This- f Degraded Voltage problem has become a regulatory issue due to the frequency of entering the limited condition of operation LCO state. Another possible regulatory issue. concerns the operation of required equipment during-accident conditions. The reason for changing the existing ERAT is due to its MVA rating.
Once the static VAR (Volt Ampere Reactive) compensator is installed and placed in service there will be the ;
possibility of' exceeding the MVA rating of the 1 transformer. The addition of the new ERAT, together with the added Static VAR Compensator will minimize degraded supply voltage problems and concerns. j l 2.1.2 While performing this test, the initialing of a procedure ,
step indicates that the step was completed satisfactorily !
p and is acceptable.
2.1.3 'The Test Director (or certified test personnel designated ;
by the Test Director) may sign for completion of '
. prerequisites or test steps. These items may be verified by personal observation, signature of responsible party, !
statement from certified personnel or operators completed documentation, or other means that the Test Director (or designee) . deem suf ficient.

CPS No. 2800.91 2.1.4 Problems may be encountered which are not related to the Testing. If this occurs, the Test Director shall evaluate the situation and note the resolution in the Test Log.
Sections of the Test may be re-performed as many times as necessary to ensure satisfactory operation.
2.1.5 Once in a section, that section shall be performed in sequence (except as noted in Section 8.2). However, sections can be performed out of sequence to allow testing to continue. (i.e. plant conditions or suppori from other departments.)
i 2 .' 2 Definitions 2.2.1 Independent Verification - The act of Two qualified individuals independently or separately verifying that an action has been performed correctly. Independent verification shall not be performed simultaneously with the action. Independent is intended to require time and distance between the act and the verification. This is denoted by a / in a procedure or document.
2.2.2 Double Verification - The act of two qualified individuals concurring that the action to be performed is correct.
This is denoted by a (DV) / in a procedure or locument.
