Dear Mr. Andrews:

.: This is to confirm our intent to conduct a survey of your emergency data j system capabilities for possible use as part of an Emergency Response Data System (ERDS). As discussed with Jim Fisicaro I have enclosed a brief

'j description of the ERDS system and the rational for considering the i concept. If acceptable to you a team of two individuals: Cheryl Sakenas, 1 NRC; ard Whitney Hansen, Comex; will be arriving at your facility at 9:00 0 . 1986 to conduct the survey. We would start with a brief

] ( M_ a.m. on July 31, introductory meeting followed by the survey of your available data and L; computer characteristics. For your information I an enclosing a list of d the individuals we expect we need to speak with and a copy of the ERDS

] '

curvey checklist to be used during the visit at your facility. Please realize that not all of the checklist will apply to your facility due to

the broad spectrum of systems that it was intended to cover. If you have any questions please contact me at (301) 492-4155.

, I EMERGENCY RESPONSE DATA SYSTEM (ERDS)

$f} - 1 The Commission has defined the NRC's primary role in an emergency at a licensed nuclear facility as one of monitoring the licensee to assure that appropriate recommendations are made with respect to offsite protective

! actions. Other aspects of our role include supporting the licensee with  ;

technical analysis and logistic support; supporting offsite authorities, )

! including confirming the licensee's recommendation to offsite authorities; j keeping other Federal agencies and entities informed of the status of the j incident; and keeping the media informed of the NRC's knowledge of the status of the incident, including coordination with other public affairs

.) . groups.

t l To fulfill the NRC's role, the NRC requires accurate timely data on ,

four types of parameters: (1) core and coolant system conditions must be

! known well enough to assess the extent or. likelihood of core damage; (2) conditions inside the containment building must be known well enough to assess the likelihood of its failure; (3) radioactivity release rates must be available promptly to assess the immediacy and degree of public danger; and (4) the data from the plant's meteorological tower is necessary to assess the distribution of potential or actual impact on the public.

-s Experience with the voice-only emergency communications link,

! i.' currently utilized for data transmission, has demonstrated that excessive s

amounts of time are needed for the routine transmission of data and of verification or correction of data that appear questionable. Error rates have been excessive; initiations have been slow; frequency of updates have been unreliable. In addition, the current system created an excessive drain on the time of valuable experts. When errors occur, they frequently j create false issues which, at best, divert experts from the real problems i for seriously long periods of time. At worst, incorrect data may cause the NRC to respond to offsite officials with inaccurate or outdated advice that results in the implementation of inappropriate protective actions.

}'.f3 The Emergency Response Data System concept is a direct electronic

L* transmission of selected parameters from existing electronic data systems, j which have been provided by the licensees for their own emergency response j facilities (ERF) . The ERDS would be for use only during emergencies at the J facilities and would be activated by the licensees during declared emergencies to begin transmission to the NRC Operations Center. NRC would
k accept the data in the format and at the update frequency that the current j licensee system can provide. The ERDS would be supplemented with voice l j transmission of essential data not available on licensees' systems rather j 4

than require a modification to the existing system.  !

/

Minimal backfitting on plant systems would be required in that j] licensees would only have to provided one additional. output port on the 3

1 SPDS or other ERF data system. Some softvare would be required for 9 assembly of the data to be transmitted. No personnel are required for j acquisition, transmission, or receipt of data on ERF data system.

'! . 1 i i Accuracy and reliability are excellent because there are no human )

i interfaces, and many systems (such as the Safety Parameter Display System l (SPDS)) will incorporate automatic data validation. Timeliness is j excellent because the system is immediately available and capable of rapid

j transmission with frequent updating. Promptness of initiation may vary j depending upon licensees' systen. configurations. In some cases, activation 0 may not occur until the licensee mans its Technical Support Center.

kj.s) Completeness is expected to be generally excellent because the primary objective of the SPDS requirement is to provide the licensee with a tool for quickly assessing the overall health of the plant, i.e., the same need that the NRC faces. Voice communications would be directed toward plant j conditions and plant response rather than individual instrument readings.

l It is recognized that the key disciplines necessary to support

't the ERDS survey will represent different departments and organizational relationships unique to each utility surveyed (e. g. , Corporate vs. Plant Site Engineering staff). It is believed that most of the appropriate personnel will be the I same as those oh the project teams for SPDS and Emergency

.j

- Response Facility Data Acquisition System development.

A j The appropriate utility manager to coordinate the ERDS site survey is likely to be' the same individual who is responsible i for SPDS, RGl.97 or ERF upgrade programs. The approximate j man-hours for each site survey are based on a 2 to 2 day j survey for a single unit site or a 2 unit site where both units are identical and a common Data Acquisition System has i been installed at a common TSC or EOF.
