3.11 EMERGENCY COOLING POND Applicability Applies to the emergency cooling pond.
Objective To assure the availability of a sufficient supply of cooling water inven-tory in'the emergency cooling pond.
Specification 3.11.1 The reactor shall not be taken critical unless the emergency cooling pond is operable with:
1.
An average water depth > 3'0",
and 2.
An average water temperature < 105F.
3.11.2 With the requirements of Specification 3.11.1 not satisfied, be in the hot shutdown condition within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in the cold shutdown condition within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.
Bases The requirements of Specification 3.11.1 provide for sufficient water inventory in the emergency cooling pond to mitigate within acceptable l
limits the effects of-a DBA with a concurrent failure of the Dardanelle Reservoir.
The minimum water depth takes int'o account (1) water loss from evaporation due to heat load and climatological conditions, (2) pond bottom irregularities and (3) suction pipe level at the pond.
1he minimum water depth and maximum water temperature correspond to conserva-tive values used to determine pond response and assure the applicability of the calculational model for pond evaporation.

Amendment No. 13
3.12 111SCELLANEOUS RADIDACTIVE MATERIALS SOURCES Applicability Applies to byproduct, source, and special_ nuclear radioact ivr iatesial sources.
Objective To assure that leakage from byproduct, source, and special nuclear radicactive material sources does not exceed allowable limits.
Specification 3.12.1 The source leakage test performed pursuant to Specification 4.14 shal!
be capable of detecting the presence of 0.005 nCi of radioactive mater-ial on the test sample.
If the test reveals the presence of 0.005 uCi or more of removable contamination, it shall immediately be withdrawn from use, decontaminated, and repaired, or be disposed of in accordance with Commission regulations. Sealed sources are exempt from such leak tests when the source contains 100 uCi or less of beta and/or gamma emitting material or 10 pCi or less of alpha emitting m-terial.
3.12.2 A complete inventory of licensed radioactive materials in possession shall be maintained current at all times.
66b Amendment No. 13
4.4.1.2.5 Test Frequency Local Icak detection tests shall be performed at a frequency of at Icast each refueling period, but in no case at intervals greater than two years except that:
(a) The equipment hatch and fuel transfer tube seals shall be additionally tested after each opening.
(b)
If a personnel hatch or emergency hatch door is opened when reactor building integrity is required, the affected door seal shall be tested.
In addition, a pressure test shall be performed on the personnel and emergency hatches every six months.
4.4.1.3 Reactor Buildind Modifications Any major modification or replacement of components affecting the reactor building integrity shall be followed by either an integrated Icak rate test or a local leak test, as appropriate, and shall meet the acceptance criteria specified in h.4.1.1 and 4.4.1.2 respectively.
4.4.1.4 Isolation Valve Functional Tests Every three months, remotely operated reactor building isolation valves shall be stroked to the position required to fulfill their safety function unless such operation is not practical during plant operation.
The latter valves shall be tested during each refueling period.
4.4.1 5 Visual Inspectio'n A visual examination of the accessible interior and exterior surfaces of the reactor building structure and its components shall be performed during each refueling shutdown and prior to any integrated Icak test, to uncover any evidence of deterioration which may affect either the reactor building's structural integrity or leak-tightness.
The discovery of any significant deterioration shall be accompanied by corrective actions in accord with acceptable procedures, nondestructive tests, and inspections, and local testing where practical prior to the conduct of any inte-grated leak test.
Such repairs shall be reported as part of the test results.
Bases (1)
The teactor building is designed for an internal pressure of 59 pais and a steam-nir mixture temperature of 285 P.
Prior to initial operation, the reactor building will be strength tested at 115% of design pressure j
and leak rate tested at the desica pressure.
The reactor building will
~
also be leak tested prior to initial operation at not less than 50% of i
83 Amendment No. 13
4.13 EMERGENCY COOLING POND Applicability Applies to the emergency cooling pond.
Objective To verify the availability of a sufficient supply of cooling water inven-tory in the emergency cooling pond.
Specification 4.13.1 'Ihe emergency cooling pond shall be determined operable by verifying:
1.
At Icast once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> that the average water depth is > 3'0".
2.
At 1 cast once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> during the' period from June 1 to September 30 that the average water. temperature at the point of discharge from the pond is 3 195F.
4.13.2 Soundings shall be made annually of the emergency cooling pond bottom to ensure that the required volume of water is available.
Bases The requirements of Specification 4.13' provide for yerification of a sur-ficient water inventory in the emergency cooling pond to handle a DBA with a concurrent failure of the Dardanelle Reservoir.
'Ihis specification ensures that Specification 3.11.1 is met. Monitoring temperature only during the period June 1 to September 30 of each year ensures that, during the hot summer months, the pond temperature limit is not exceeded.
During other periods of the year the pond temperature will not have the pot'ential to reach temperatures near 105F.
110a Amendment No. 13
4.14 RADIOACTIVE M\\TERIALS SOURCES SURVE1L1.ANCE Applicability Applies to leakage testing of byproduct, source, and special nuclear radio-active material sources.
Objective To assure that leakage from byproduct, source, and special nuclear radioactive material sources does not exceed allowable limits.
Specifict. tion Tests for leakage and/or contamination shall be performed by the licensee or by other persons specifically authorized by the Commission or an agreement State, as follows:
1.
Each sealed source, except startup sources subject to core flux, contain-ing radioactive material, other than Ilydrogen 3, with a half-life greater than 30 days and in any form other than gas shall be tested for leakage and/or contamination at intervals not to exceed six months.
2.
The periodic leak test required does not apply to sealed sources that are stored and not being used.
The sources excepted from this test shall be tested for. leakage prior to any use of transfer to another user unless they have been Icak tested within six months prior to the date of use or transfer.
In the absence of a certificate from a transferer indicating that a test has been made within six months prior to the transfer, sealed sources shall not be put into use until tested.
3.
Startup sources shall be Icak tested prior to and following any repair or maintenance and before being subjected to core flux.
