315 92003 DRS Special electrical distribution system functional inspection in accordance with Temporary Instruction (TI) 2515/107 (25107).
Results:
The team determined the electrical distribution system was functional and engineering and technical support was adequate.
A summary of strengths and weaknesses in system design and engineering support is provided in the Executive Summary of this report.
Four unresolved items were identified regarding completion of the EDG load study (Section 3. 1. 14), monitoring of degraded grid conditions (Section 3. 1. 19),
dc short circuit calculations (Section 3.2.2),
and ac fuses in dc applications (Section 3.2.4).
Six open items were identified regarding completion of 4kv short circuit calculations (Se'ction 3. 1. 11), revision of procedure to preclude operation at voltage higher than equipment rating (Section 3. 1. 18), completion of calculations for 9205050084
'720421 PDR ADOCK 05000315 G
