Topic XI-2 is being resolv.ed under NRR Generic Items A-02 and* s.. 57,, "Effluent and. Process: Monitoring. Instru-mentation.....
Resolutton of Generic Items A-02 and B-35 will primarily result in Technical Specificat*ion* changes and minima:l hardware: changes.

Definition:
A generic review of *all operating plants to determine their capability to comply with Appendix I, 10 CFR SU, and to prevent explosions in the gaseous radwaste system is currently unden-iay.
2.. Safety CJbjecti ve:.
- To provide assurance tha.t radioactive gaseous effluents from the faci 1 ity can be kept. "*as low as reasonaD ly a chi evabl e" as defined in Appendix I,.
lu CFR Part 50, and to as~ure adequate control of the mixtur~ of gases in* the* gaseous radwaste system to prevent explosions.

- TO CFR Pa,rt: SU, is currently unden-iay Dy DSL Upon the.. completion. of this*
revi-ew,. new gaseous and liquid. 'radiological effluent ana monitoring techni.cal specifications. will* De issued* to all ORs.

Basfs. for Deletion Topic. XI-1 is being* resolved by the following NRR generic topics:
- 1)
A-02,. "Appendix !
11 and 2) B-35, -"Confirmation of Appendix I Models.

- Res_olutton* of these-two generic topics will primar*ily result in Technical Specification changes and may require*some mfnor hardware changes.
At present nothing more than the a~dition of monitoring instrumentation is foreseen.
The implementation of Appendix I will; therefore, not affect the integrated assessment for SEP plants.
.In addition,. the implementatfon of Appendix I will result in limiting conditions for operation to assist licensees*in keeping the amount of radioactive material released. in. effluents to unrestricted areas as low:
as is reasonably achievabl~. Since licensees are currently restricted in the types and amounts of effluents they can release-~ implementation of* additional restrictions.on *releases*shou.ld not impact operation of th~* plant.
Based: on the above*:we have deleted Topic XI-1 from the SEP program.

.. r DEFINITION
.TOPIC:
XI-2. Radiolooical (Effluent and Process) Monitorina Systems
- l. Definition:
Onsit~ radiolooical monitoring systel'T'ls:are used to:
- a.
assess the proper functioning of the process and wttste treatment
- systems, b *.
assure that radioactive releases do. not exc@ed* the aporooriate quidelines, and C.
measure actual.releases to evaluate their envirOnMental ilTlpact.
There is concern about the adequacy of radiation monitorino systel'T'ls.
A survey of 12. pl ants ha.s been initiated.
The results of this survey will indicate whether this area. needs to be rev*i ewed* for a 11 ooerati nq*
plants..
qe-review would include the monitor's sensitivity, ranqe, location, and: ca*librat.ion techniqlleS *.
2: *.. Safety Ob.i ecti ve:
To provide reasonable assurance that* the* 1 icensee adeauately l'loni tors the releases of radioactive Materials. in liai1id* and oaseous effluent and that the releases are properly restricterl~ *To orovide assurance ttiat the licensee. adequately IT'IOnitors. the ooeration of eauio!Tlent that

Basis for Deletion Topic. XI-2 is being resolved by-~ the followfng NRR generic topics:: 1)
A.-02,. 11Appendix r** and 2} B~67,~nEffluent and. Process Monitoring Instrumentation." A-02 is discussed in Topic XI-1.
Generic item B-67 was: suodivided into four subtask.
We believe that events since the inceptiorr of B-67 hava largely addressed the identified concerns or changed* our thinking in regard to thetr safety significance.
The
.description* and E>ases for deletfon of each subtask are presented below-.:

.;; *.r Subtask l: Monitoring of Radioactive Materials Released in Effluents Item III.D.2.l, Radiological Monitoring of Effl~ents.requires an NRR evaluation of modifying. effluent monitoring design criteria based on iMI-2 and their experiences.
- Item II.F~ l (l ), Noble Gas Effluent Monitor of Clarification of the TMl Action Plan Requirements (NUREG-073T).is. being. implemented to require adequate monitorfog capability during accident conditions.
Subtask 2:.Control of Radioactive Materials Released _in Effluents The purpose. of this subtask was to review plant operating histories and prepare NUREG reports documenting the eva1uatiQns and recommending solutions to identified problems.
Various, staff act.ions sirice 1978 (including NUREG reports. and IE Bulletins) have resulted in the: staff conclus.ion that no continuing*
need for additional staff guid~nce exists-Subtasl<* 3*:
Effects. of Accidental Liquid Releases. on.Nearby Water s*uppltes:
The* purpose of this task. was to 'perform a* generic. analysis of the con-sequences. of 1 iquid.tank failures for those plants which received their license* prior* to issuance* of the Standard Review Pl an (.SRP-).
Experience in performing SRP anaJyses for* newer pl ants has indicated that-;t is-highly unlikely" that radioactive concentrations in the.
nearest potable water* supply could exceed TO CFR*Part 20 values.
Subtask 4:
Performance of Solid _Waste Systems The purpose of subtask 4 was to perform an industry wide survey*
to determine the extent to which power ~l~nt~could process wastes and to develop plans fbr upgrading.existi~~ systems or adding new systems..
. The* NRc* position relative. to* a requirement for an operable installed solid radwaste system has changed. and,.* therefore, this subtask is no l anger* appropriate..
For. the: above* reasons,. Issue B~67 is being deleted from the NRR list of generic issues.
Since issue B-67 is being deleted, only Generic Issue A-02, "Appendix I" is appropriate to this topic.
The* resolution of' issue A-02 is described in our Basis for Deletion of Topic XI-1.
Topic Xl-2 is being deleted from the* SEP program for the same reasons.
