CHERNOBYL RADIATION RECONNAISSANCE ROUTE: An exclusive advanced information trip into the Chernobyl area… and much deeper.

The PRYPYAT.COM team has decided to further extend our cooperation with Sergii Mirnyi, and invited him to be the principal guide-instructor for the advanced information trip to the Chernobyl area (which we announced earlier). The offer was gratefully accepted, and designed was the following

PROGRAM for
Exclusive advanced information trip
into the Chernobyl area… and much deeper
CHERNOBYL RADIATION RECONNAISSANCE MISSION ROUTE
Saturday September 15, 2007

For the first time ever, the trip ‘Chernobyl radiation reconnaissance mission route’ makes public a successful professional and personal experience of Chernobyl victors – the radiation reconnaissance men. It combines it with the most advanced front-line knowledge of many diverse sciences, relevant to Chernobyl radiation accident and contemporary disasters, and delivers it in an understandable, normal human language and, moreover, even entertaining format – against the background of the most controversial patch of land at the globe, a so-called Chernobyl ‘dead’ zone of nowadays… and a likely Chernobyl national park of the future. The route of the trip follows the actual route of the first radiation reconnaissance missions, and weaves amidst impressive signs of the nuclear unit’s explosion and its effects’ mitigation, the colossal ruins and depopulated land with breathtakingly beautiful landscapes and flourishing wildlife.
The advanced trip is designed both for professionals, students and advanced general public, who are concerned with the issues of radiation, contamination and health in connection with the environment we live in now.

The trip will intellectually equip, practically train and psychologically empower you to successfully survive contemporary contamination accidents, especially radiation ones, or/and mitigate and study them. Moreover, the 1-day tour will teach you to navigate among the contemporary technogenic contamination hazards – both everyday ‘normal’ and extreme catastrophic ones. All this is achieved by employing the unique intellectual gainings of the Chernobyl radiation accident and possibilities of a present-day area with official name ‘the Chernobyl alienation/exclusion zone’ (Chernobylskaja zona otchuzhdenija). The educational trip generalizes and delivers in a nutshell a two-decade successful professional and personal experience of Chernobyl reconnaissance men, supported by a front-line complex multidisciplinary research of Chernobyl and contemporary disasters, and shaped in an entertaining and user-friendly way by vast and invariably successful international lecturing expertise of the principal guide-instructor.
The guide-instructor Sergii Mirnyi was a commander of radiation reconnaissance crew and platoon inside the Chernobyl zone several months after the explosion. He was the officer, responsible for management of the company’s radiation reconnaissance missions, and was cited for bravery and heroism by the Commander of Kiev Military District. He has MSc in physical chemistry and MSc in environmental sciences and policy, complemented by the courses of social sciences and humanities (history and literature). Now he is an expert in Chernobyl and the mitigation of radiation and ecological disasters, the author of scientific monograph on the actual state of the Chernobyl mitigation workers’ (liquidators’) health and several important international generalizing papers on Chernobyland regularities of contemporary disasters. He also wrote several books of Chernobyl prose, already translated into English and Hungarian, and two screenplays, decorated at prestigious international competitions Koronatsija slova [Crowning the word] (Kiev-2005) and Kinostsenariy [Screenplay] Magazine Competition (Moscow-1997).
For more info about the trip guide-instructor seeexcerpts of his earlier books, a recent pripyat.com-publication of his abstract for the conference on environmental education, and an announcement with report about a recent presentation of his screenplay.

During the exclusive advanced information trip YOU WILL:
- gain practical skills of successful survival in the circumstances and of research and mitigation of a contemporary contamination (and particularly radiation) accident, the skills well-checked and proven to be true by more than two decades of life and work of the Chernobyl radiation reconnaissance men
- measure radiation levels at the carefully selected set of representative points outside and inside the Chernobyl zone
- visit the most famous Chernobyl places: the Sarcophagus over the remnants of the exploded reactor of the Chernobyl nuclear power plant, the ghost town of Prypyat, the capital of the zone – the Chernobyl-town, several abandoned villages (one of them fully bulldozed), and – a special trait of this tour – the exit decontamination depots and the site of the military camp of the 25th brigade of chemical and radiation protection, which included a separate battalion of radiation reconnaissance
- acquire the skill of adequate comprehension and correct interpretation of the maps of contamination (both radiation and chemical)
- learn the general pattern(s) of the contamination spatial distribution and its intricate, sometimes quite unexpected changes with time, caused by mitigation works and natural reasons
- be introduced to the universal holistic model of a contemporary single-point contamination accident/catastrophe as a phenomenon in natural and social environments

Chernobyl. Dark side of sarcophagus.

January 11th, 2007 by WickLi

Unique documental film inside Chernobyl sarcophagus. Filmed by Chernobyl NPP video

operator Sergey Koshelev. This video is much more interesting than well known film by National Geographic and BBC Horizon.

Investigations Chernobyl Shelter

December 12th, 2006 by WickLi

Started during the first days after the accident complex diagnostic investigations were continued after Shelter object construction completion. Main arias of investigations were:
• сlarification of quantity and location of nuclear fuel inside the Unit;
• determination of fuel containing masses mechanical, physical and chemical condition;
• nuclear and radiation safety assessment;
• creation and operation of diagnostic systems;
• facility’s constructions reliability monitoring.

Investigation of the Shelter object started from hols drilling. Results of these investigations provided wide volume of information. It was possible to determine character of internal damages, constructions condition, to penetrate to fuel congestions and to sample fuel containing materials (FCM), to measure directly neutron multiplication factor in congestions, which showed that FCM in the Shelter were in subcritical state. It was established, that inside the Shelter the fuel was in the form of destroyed reactor core fragments, stark glassy mass (lava) and fuel dust.
Results of drilling allowed to determine new penetration ways into the Shelter premises and stimulated creation of the special diagnostic robots for works implementation inside the sarcophagus.

Investigations Chernobyl Shelter

Initial large-scale works on Shelter’s constructions reinforcement were started in 1987 and completed in 1989. It was revealed three zones requiring urgent anti-emergency measures: deaerator stack, main circulating pumps premise and premise 805/3.
In spit of additional measures on constructions reinforcement, experts understood, that in existing status the Shelter couldn’t be considered as facility, safety of which is ensured for decades.

Accident

December 4th, 2006 by WickLi

At 01 hr 23 min 49 sec Moscow time on April 26, 1986, the world’s worst-ever nuclear disaster occurred at Power Generation Unit No.4 of the Chornobyl NPP. As a result, the reactor core was destroyed completely, and almost all its supporting structures were severely damaged. The reactor and its building were destroyed by two powerful explosions. The upper biological shielding of the reactor (scheme “E”) was torn off and turned at 15° to the vertical. All high-pressure pipes were destroyed. Hot graphite blocks, fragments of pipelines and equipment were thrown outside. Most of the debris piled up at the north wall. The explosion destroyed the separator room. All the four separators, each weighing 130 tons, were moved from their supports and torn off from the pipelines.

Chernobyl Accident

The roof collapsed and hung down on the separators.
