other water-induced damage at the site. 'The information should cover the possible
hydrologic events, their causes, historic and predicted frequencies, and potential
consequences to the reactor facility. The water table should be located, and the
potential for radioactive contamination of ground and surface waters should be
discussed.
Acceptance Criteria
The acceptance criteria for the information on hydrology includes the following:
* :The facility is located and designed to'withstand credible hydrologic events.
Locations of particular concern include'a flood plain, downriver of a dam,
and close to the seashore and sea level.
Potential events it the site that could cause nearby hydrologic
consequences are shown not to present significint risk to the facility.
* Facility design bases are derived sufficie'ntly from predicted hydrologic
events that there is reasonable assurance that such events would not
preclude safe operation and shutdown of the reactor.
* The reactor facility design bases contain provisions to mitigate or prevent
uncontrolled release of radioactive material in the event of a predicted
hydrologic occurrence. Potential consequences of such an event are
considered or bounded by accidents analyzed in Chapter 13 of the SAR.
* Facility design bases consider leakage or loss of primary coolant to ground
water, neutron activation of ground water, and deposition of released:
airborne radioactive material in surface water.
Revew .ocedures ..
The reviewer should verify that the site has been'selected with due consideration of
potential hydrologic events and consequences, including any that could be initiated
by either local or distant seismic disturbances. In addition, the reviewer should '
ascertain the design bases incorporated into the facility design to address predicted
hydrologic events, accidental release or leakage of primary coolant, and
radioactive contamination of ground or surface waters
Evaluation Findings - -.
This section of the SAR should contain sufficient information to support the
following types of conclusions, which will be included in the staffs safety
evaluation report:
