AMENDMENT TO FACILITY OPERATING LICENSE l
Amendment No. 147 License No. OPR-49 l
1.
The Nuclear Regulatory Commission (the Commission) has found that:
A.
.The application for amendment by Iowa Electric Light and Power Company, et al, dated October 17, 1984,'as supplemented by a letter dated April 30, 1986, complies with the standards and requirements of the Atomic Energy Act of 1954, as amended (the Act), and the Commission's rules and regulations set forth in 10 CFR Chapter I;
}
8.
The facility will operate in conformity with the application, the provisions of the Act, and the rules and regulations of the Commission; C.

in :this piping when the punp and/or peps. are started.
If a water hammer were to occur-at the time at which the system were required, the. system would still perform its design function.
However, to minimize damage 'to the discharge piping, Specification 3.5.H requires that the core spray and LPCI discharge piping
~
pressure _ be restored within one hour after system depressurization :
l
' when the system is required to be operable.
Likewise, for HPCI
]
and 'RCIC, the discharge piping to'the last block ' valve shall be filled when these systems are required to be operable.
If the discharge piping pressure for the core spray and LPCI subsystems cannot be restored within one hour or the discharge piping for HPCI and RCIC cannot be maintained in a filled condition to the last block valve, the operator is required to perform either of y
the following actions:
)
1) place the affected system (s) in the test mode which will ensure that the discharge piping is filled with water, or
- 2) -declare the affected system (s) inoperable in which case the operator will enter the applicable-LC0 for the affected system (s) as defined in Specification 3.5. A (core spray and LPCI), 3.5.0 (HPCI), or 3.5.E (RCIC).
The above actions minimize the possibility of a water hammer and are considered conservative in nature.

Engineered Safeguards Compartments Cooling and Ventilation One unit cooler in each punp compartment is capable of providing adequate ventilation flow and cooling. Engineering analyses indicate that the temperature rise in safeguards compartments i
f without adequate ventilation flow or cooling is such that continued operation of the safeguards equipment or associated f
auxiliary equipment cannot be assured, l'
