- 3/4.11.1 LIOUID EFFLUENTS CONCENTRATION LIMITING CONDITION FOR OPERATION 3.11.1.1 The concentration of radioactive material released from the site (see Figure 5.1-1) shall be limited to the concentrations specified in 10 CFR Part 20, Appendix B, Table II, Column 2 for radionuclides other than dissolved or entrained noble gases. For dissolved gr entrained noble gises, the concentration shall be limited to 2 x 10 microcuries/ml total activity.

APPLICABILITY: At all times.

ACTION:

With the concentration of radioactive material released from the site exceeding the above limits, immediately restore the concentration to within the above limits.

SURVEILLANCE REOUIREMENTS 4.11.1.1.1 The radioactivity content of each batch of radioactive liquid waste from the radwaste system tanks shall be determined prior to release by sampling and analysis in accordance with Table 4.11-1. The results of pre-release analyses shall be used with the calculational metods in the ODCl! to assure that the concentration at the point of release is maintained within the limits of Specification 3.11.1.1.

4.11.1.1.2 Post-release analyses of samples composited from batch releases shall be performed in accordance with Table 4.11-1.

The results of the previous post-release analyses shall be used with the calculational methods in the 00CM to assure that the co.ncentrations at the point of release were maintained within the limits of Specification 3.11.1.1.

4.11.1.1.3 The radioactivity concentration of liquids discharged from continuous release points shall be determined by collection and analysis of samples in accordance with Table 4.11-1.

The results of the analyses shall be used with the calculational methods in the ODCM to assure that the concentrations at the point of release are maintained within the limits of Specification 3.11.1.1.

r 8.1 SPECIFICATION 3/4.11.1 Prior to initial criticality, the requirements for sampling and analysis for items A.6, A.7, and A.9 in Table 4.11-1 may be waived provided the release is through the turbine building sump (item B.2 of the Table 4.11-1).

8.2 SPECIFICATION 4.8.1.1.2c The surveillance requirements for verifying diesel generator voltage and frequency during diesel generator starts is waived for the original surveillance interval only.

8.3 SPECIFICATION 4.7.8.1, ITEM D 3 The 1/4 inch negative pressure requirement within the spent fuel storage area and ESF pump rooms is waived during the low power test program.

However, the auxiliary building gas treatment system shall be capable of naintaining these areas at a slight negative pressure during this period.

8.4 SPECIFICATION 3.3.3.10, TABLE 3.3-13, ITEM 33 Flow rates for ventilation systems for the shield building exhaust, acxiliary building and service building cay be estimated using the design flow rate for the apprcpriate fans.

This interim waiver extends the 30-day limit for 18 months from the issuance of this license.

This waiver is considered to be an interim measure until flow rate monitors for the ventilation system for these structures can be repaired or replaced.

8.5 SPECIFICATION 3.3.3.9, TABLE 3.3-12, ITEM 30 Prior to initia? criticality, discharge from the Cooling Tower Bloudown Effluent line may continue with an inoperable flow monitor p ovided that flou is estimated every 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> during discharge.

The-reactor-trip logic was modified at NRC request.

However, the draft technical specifications were incorrectly prepared.

This change reficcts the NRC approved' reactor' trip logic.

2.

ACTION 36, PAGE 3/4 3-77 1

TThe present wording of ACTION 36 allows no time for the channel (iodine

or particulate sampler) to be: inoperable before auxiliary sampling starts.

This change would allow us~four hours to correct the situa-tion'or start auxiliary sampling without requiring prompt LER notifica-i tion.'

The 30-day idea is consistent with the general philosophy of standard technical specifications.

f 3.'

SPECIFICATION 3.7.1.2, PAGE 3/4 7 The steam driven auxiliary feedwater pump cannot be demonstrated OPERABLE before entering MODE 3; there is not sufficient steam available in MODE 4.

This change should be considered generic to all PWR standard technical j'

specifications.

i 4.

SPECIFICATION 3.9.1, PAGE 3/4 9-1 The present valve list does not allow for makeup to the Refueling Water Storage Tank during MODE 6.

The proposed change allows for makeup while

.still preventing an inadvertent dilution of'the reactor coolant system.

SPECIFICATION 3.10.5, PAGE 3/4 10-5 l

Position indication calibration is done with bank withdrawal, not individual 1 control rod assembly withdrawal.

This change is consistent with Westinghouse standard technical specifications.

L 6.

SPECIFICATION 3.11.1.1, PAGE 3/4 11-1 r

This change reflects the fact that only the batch releases from the radwaste system will have radioactivity content determined before release.

Batch releases from the condensate deminera.lizer regenerant.

tanks will be. sampled'with a' composite sampler during release.

. TABLE-4.ll-1, PAGE 3/4 11-2-& 3/4 ll-2a This change separates the_ releases from the radwaste system and the con--

^densate demineralizer_regenerant tanks. The radwaste. system releases will~be. batch type with sampling and. analysis before release.

The

. condensate deuineralizer regenerant tank releases will'be batch with

- the. release path subject to composite sampling during release.

The-release path for demineralizer regenerant tanks is. equipped with a radia-ition monitor that has isolation capabilities which will prevent releases of liquid:with unusually high 'oncentrations of radioactive materials.

8.

SPECIFICATION 3.11.2.1, PAGE 3/4 11-8 The present e,ecification is applicable at all times.

The change that is proposed will allow for some relaxation of the sampling requirements during MODES 5 and 6.

The specific relaxation request is listed below.

9.

TABLE 4.11-2, PAGE 3/4 11-11 The present sampling requirement for containment purging requires a grab sample analysis before initiation of containment purge from any compartment. The proposed change eliminates the sampling requirement during the periods when containment integrity is not required, namely MODE 5 and MODE 6 when fuel is not being moved. This change would enable us to start and stop the purge fans without having to grab sar ple an open containment.

The containment purge fans exhaust to the shield building vent which is continuously monitored and sampled on a regular basis.

10.

SPECIFICATION 6.9.1.13, PAGE 6-21 Correction, specification 6.9.1.8.c does not exist.

11.

SPECIFICATION 8.5, PAGE 8-1 The flow monitor is not functioning properly, and we do not expect to have it repaired before the 30-day outage limit expires on April 2, 1980.

We are proposing a change to allow us to extend the outage time until initial criticality. All sampling requirements and limits will be met before release.

Flowrates will be estimated during the release periods.

In addition, no radiological hazard till exist until initial criticality.
